Here is a simple slide show with a simplified breakdown of when to make what cuts to produce a short productive fruit bush. Thank you Chuck Ingels. For apples, pears, asian pears, and cherries this strategy is especially effective. For peach, nectarine, pluot, plum, and apricot a little more finesse can make a big increase in fruit yield. More on that later. Either way, this general method is the outline for maintaining all school orchard trees. </div>

When fruit is dropping and birds are feeding in the tree, chances are you're approaching harvest time for that crop. Then apply the taste test. These are perhaps the easiest ways to determine harvest time in the School Orchard, with its multiple varieties of trees.<br />
<br />
<b>B - "More in Depth"</b><br />
For the Apples, you should be able to indent the skin and flesh with your finger nail, and when you cut it open the seeds should be dark brown or black. If seeds are still light color, you're not quite ready for harvest. If there is good sunlight on the apple, and the nights are cold, some red color will still develop.<br />
<br />
Be careful when harvesting the Apple! Lift it with a little twist. It should separate at the stems abscission zone (that's the little wider area near the tree end of the stem). If it doesn't come away easily... leave it on the tree. The risk is breaking the little gnarled "Fruiting Spur." In Apples, the Fruiting Spur should bear fruit for 10 or more years. Some instruction for the students and helpers will keep your Apple tree bearing for years, otherwise you'll have to wait for another Spur to develop! Apples ripened on the tree taste great. Let the students have a harvest party, and eat the apples right there.<br />
<br />
"Asian Pears" (e.g. Chojuro, Shinseiki) can be harvested like the Apples, and eaten right off the tree. Use the same "ripeness" criteria. They will usually turn from green to a yellow buff color, even almost tan to russet. And for Pears.... treat the Spurs the same as Apples. They wont last quite as long, but they set fruit at the same spot year after year. The most frequent harvest problem in the School Orchard is that kids pick the fruit prematurely, and "pull" the apple or pear down, breaking the Spur.<br />
<br />
"European" Pears (e.g. Bartlett) can be picked when they are full sized, but still green and firm. They should then be stored in a refrigerator for at least a week, then taken out and allowed to ripen. These are not eaten "tree ripe." When ripened on the tree, they tend to get "mealy."<br />
<br />
Your Stone fruit (Peaches, Plums etc.) are probably all harvested by now, but if not, they should be allowed to ripen (soften) on the tree and eaten fresh. The Persimmons should be ready from October to November, in most regions. Both common varieties should be bright, shiny Orange in color. The flat, squat shaped ones, the "Fuyu," should be eaten when they are firm, like an apple. The acorn shaped "Hachiya" must be almost custard soft before you give them a bite! (but they can ripen off the tree) If you mix the two up you're in for a mouth puckering surprise! Persimmons should be harvested by cutting the stem (there are harvest clippers that are shaped like your two fingers when you make a cutting sign.MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-68999486951177708542008-08-07T20:03:00.000-07:002011-09-13T20:03:59.491-07:00Fall Fertilizing<div>
<b>A - "Keeping it Simple!"</b></div>
<div>
</div>
<div>
Right after
Harvest, You can give the trees another application of Fertilizer
similar to our Spring/Summer suggestions. Or, spread about 2 to 5 pounds
of compost per tree in a 6" band around the drip line, under the mulch.
(Keep away from the Trunk!)</div>
<div>
</div>
<div>
If it's later in the
fall: sit back....enjoy the view of the School Orchard, do nothing,
think about the pleasures of Dormancy...... Lucky trees! </div>
<div>
</div>
<div>
<b>B - "Hey, wait a minute what's going on here!" </b></div>
<div>
</div>
<div style="text-align: left;">
All
that food and stuff from the leaves (starches, carbohydrates, sugars,
pigments, water etc. etc.) has been retrieved (sucked back actually) by
the trees..... before they actually dropped the leaves. All that food is
stored in the trunk and roots. In the Spring, before there can be any
energy production from leaves, the "sap" will come rushing up from
storage to fuel the whole works. Vermonters will tap off some as "Maple
Syrup" for Pancakes, and Southeast Alaskans will tap off "Birch Syrup"
for their biscuits. It's sweet 'cause it's loaded with sugars and
Energy. </div>
<div>
</div>
<div>
Don't worry there will be plenty to do later, but in the School Orchard more Fertilizer is usually not needed! The exception is:</div>
<div>
If you've noticed a deficiency (yellow leaves during mid-summer), post-harvest is a good time to correct the deficiency. </div>
<div>
Short of doing a leaf analysis, the Compost application is your best shot at fertilizing and correcting the nutrient deficiency.</div>
<div>
</div>
<div>
<i><b><u>Hint:</u> </b>Supermarket
Chains in Los Angeles County have their day old and wilted Produce
professionally composted. Vons especially has been very happy to donate
compost to our School Gardens and Orchards. The Compost is Superb!! It's
arranged through the Manager of the neighborhood Market in the School's
community. It's likely done by chain Markets throughout the State.
Their objective is to sell the Compost to Organic Farmers. A
neighborhood manager can donate a load to your School Orchard. Be
grateful... and post a sign thanking them.... the school garden and
orchard can be a real link between school and community.</i></div>

<b><span style="font-size: x-small;"> A - "Keeping it simple!"</span></b></div>
<div>
</div>
<div>
August, (and perhaps the first few weeks of September) is the best time to prune the Apricot and Aprium trees.</div>
<div>
With your Pruners and Loppers remove any "suckers," cut out Dead, Deformed, Damaged, and Crossing shoots and branches.<br /></div>
<div>
Remove
the "Water Sprouts." These are the paradoxically very green and healthy
looking shoots, that you might think are "good" to save..... they're
not! They usually grow from interior branches, are this years growth,
and grow straight up to the sky with no branches (they will rarely have
any fruit!)</div>
<div>
</div>
<div>
The lateral branches (reach out
with your arms) will have the shoots with fruiting spurs. For the ones
that grew this year (green bark) visually divide the shoot into four
sections, starting from the origin,.... cut off the outermost one, of
the four sections (that is: reduce the length by 20-25% of the shoot's
length).</div>
<div>
</div>
<div>
Try to cut the shoots or branches
at a point about 1/4 inch out from a bud or node. It's best if the bud
(node or shoot) is pointing in the general direction that you want the
branch to grow (e.g. not pointing down.... or towards the
central/interior area of the tree). If you have to remove a branch
entirely, make the final cut just outside of the little "collar" where
the Branch originates from the Trunk. Don't leave a "stump." </div>
<div>
<b> </b></div>
<div>
<b>B - "More in Depth:"</b></div>
<div>
</div>
<div>
Post
harvest, or late "summer" pruning is particularly useful if trees have
been growing too vigorously, and are getting out of control (too high).</div>
<div>
Summer and post harvest pruning has a modulating effect on tree growth. On the other hand: Pruning <u><i><b>after</b></i> </u>leaf drop is a great stimulant to spring growth!</div>
<div>
<b>APRICOTS </b> should<i> <b>NOT</b></i> be pruned any later than early September. So this is the last time you can prune them before mid-summer next year.</div>
<div>
Apricot
pruning wounds are subject to a disease (Eutypa Dieback) the organism
is spread by rain. The pruning wounds need 6 to 8 weeks of dry</div>
<div>
weather to properly heal. </div>
<div>
The
Water Sprouts can be thought of being like your Appendix.... it
probably once did.... but no longer has any real function. Probably
genetically left over from when the tree had to "get up there" to
compete for light from its surrounding trees. These shoots rarely if
ever bear any fruit.</div>
<div>
</div>
<div>
You also want to remove
shoots growing towards the center of the tree. This allows air to
circulate and sunlight to penetrate to the interior.</div>
<div>
If you
shorten the shoots (the 25% number), you'll be keeping the fruit more
towards the trunk and major branches and reduce the chance of breakage.
The remaining spurs will now bear larger and healthier fruit.</div>
<div>
</div>
<div>
For all the trees, it's a good time to remove branches that have broken under the weight of fruit</div>
<div>
<i>("really herb, where have <b>you</b> been!....... Some Orchard in Fresno!") </i> ........Just wait your trees will get there. </div>
<div>
</div>
<div>
<b>C - "Some more Background:"</b></div>
<div>
- A good time for pruning <i>over-vigorous trees</i> is after harvest, before dormancy. The other trees are best pruned later,</div>
<div>
in
the Dormant period. Broken or cracked limbs or branches (some say a
Shoot becomes a branch when it's 1 yr old) are a place for disease entry
(like any wound). It's best to remove those branches, back to a proper
location. The area of a bud (those little swellings, or a leaf node)
contains the hormones necessary for proper healing. The smooth sections (<i>internodal area</i>) will not heal, they'll just die back to the bud, and you've not accomplished much. <br />If
the bud (or shoot) is pointing to the direction you want the limb to
grow, your cut will also have "training" value. The Branch <u>Bark</u> <u>Collar</u>,
at the origin of the branch, has the healing potential to close over
the wound (take a look at some old pruned trees). A stump that protrudes
will heal poorly, if at all. Pruning paints or sealers are not
recommended. It's far better to place the cut in an area of good
natural healing.</div>
<div>
</div>
<div>
Dead shoot ends (black and
really dry) may have been invaded by a borer, or bacteria. The dead,
wilted and shrivelled leaves may still be hanging down and attached.
Prune these shoots off (don't cut through the dead part, go back a ways
to where the shoot is normal looking. Diseased branches may have a
bacterial or fungal infection. These branches will often have an area of
disrupted bark, and oozing a somewhat resinous, brown or black sticky
fluid. Cut these branches back at least a foot from the wound, so that
you are in healthy looking wood. (Nice intact bark and cambium layer,
with uniform and light cream colored sap and heart wood (not stained
brown or black). </div>
<div>
</div>
<div>
When pruning out dead twigs
or branches (particularly if they look diseased; oozing, crusting) leave
a healthy margin of normal looking branch (up to about 12" if you can)
to get well beyond the bad part.</div>
<div>
</div>
<div>
Cut out <b>crossing branches</b>,
the areas where they rub are subject to wounding and disease entry.
Leave the bigger, or better oriented branch. (Or make an "executive
decision" and leave the one that YOU like best. Hey..... you're doing
the work! Michael understands.)</div>
<div>
</div>
This is also a
good time to prune the Citrus trees of any dead branches or twigs, and
any branch ends that are dragging on the ground. When you have access to
the trunk, renew the "Tanglefoot." If you can keep the ants out of the
Tree you're probably 90% to good disease control. Often, nothing more is
needed. (Ants kill the Beneficial's larvae that are feeding on the
Pests...... that's not good) <div>
</div>
<div>
Except for the Apricot (remember?), you will probably want to do some <i>Winter Pruning</i> on your trees...... </div>
<div>
but more about that in the next newsletter.</div>
<div>
<i><b> </b></i></div>
<div>
<i><b>And
remember! with any diseased branch... or going from Tree to Tree.....
always sterilize your pruners between cuts, by dipping</b></i><b><i> the blades in 70% or 90% Drugstore Alcohol (Isopropyl).</i></b><i><b> When you're finished, wash off the pruners and spray or apply a protective oil.</b> </i><b><i>Afterwards </i>I always resharpen my Pruners, and spray metal parts with an oil protectant like "WD-40."</b> </div>
<div>
</div>
<div>
<b>Cleaning your Tools between "Cases", is just like washing your hands. <i>BECAUSE..... You're Doing Surgery!</i> And wear your goggles!!</b></div>

These are, for the most part, general measures designed
for the overall health of the Orchard. Occasionally additional measures
may be useful for a specific Pest that has gotten out of control. The
objective is to have an overall strategy that maintains a healthy
ecosystem for plants, critters, and people,and encourages beneficials.
It's called<b> IPM</b> (Integrated Pest Management). The point of the
Newsletter is to help you keep your trees healthy and vigorous by good
cultural methods, so they can resist disease with a minimum of
additional intervention. </div>
<div>
</div>
<div>
<b>A - "Keeping it Simple!"</b></div>
<div>
</div>
<div>
Make
sure the Team has done a good job on the "Clean-up," and check for any
"mummies" left on the tree. Remove any residual leaves and hose off the
tree using a pressure-spray nozzle. It's beneficial to see that all dead
leaves are removed from the tree, and raked up. For the Apple Trees;
cut a 3 inch wide strip from a corrugated cardboard box, and wrap it
tightly around the trunk (so the little tubes are<b><i> vertical),</i></b>
just below the first branch (or about a foot and a half above the
ground). Remove the band on December 1st, put it in the garbage pail
(not for garden composting). </div>
<div>
<b><span style="font-size: small;">* </span></b>If
there has been a severe infestation of soft bodied insects or scale a
"Horticultural Oil" can be sprayed during the Christmas Vacation period,
when children are away, and when the Tree is dormant. </div>
<div>
</div>
<div>
<b>B - "More in Depth"</b></div>
<div>
</div>
<div>
<b>OK -</b> The
Corrugated Cardboard band will catch Codling Moth Larvae as they travel
down to the ground to pupate. Removal in early December should catch
some of the larvae in the little corrugations. Best to burn, or dispose
of these with trash. This will help reduce the Codling Moth population
in the coming season, although, if you had a heavy infestation we'll
have more suggestions for Winter and Spring.</div>
<div>
</div>
Obviously-diseased
shoots and branches can be Pruned out when the tree has gone dormant
and you're removing residual leaves. (The tree begins going Dormant when
at the ends of the twigs the tiny leaves have been replaced by a tight
Leaf Bud. This is where growth will be initiated in the
spring <br />
<div>
</div>
<div>
<b><i>* Spraying of pesticides
(organic or chemical) should only be done if there is evidence of
disease uncontrolled by the physical and mechanical techniques. There is
always the risk of upsetting the natural balance by injuring the
beneficial insects and microbials. When appropriate however, spray
strategies can be used.</i></b> <br />
<br />
If you're concerned about the
level of disease in some trees, call your County Master Gardener office
and request a visit from one of the Master Gardeners. The School holiday
weekends and holiday weeks during November, December, and January are
the best times to use preventive sprays (like Horticultural Oil), and to
deal with a School Orchard disease problem.</div>
<div>
</div>
<div>
<b>C - "Why is that ?" </b></div>
<div>
Many
insects and pests (soft bodied insects, scale, etc.) over-winter in the
crotch of branches, in the bark, and even in the bud tips. Although
dormant, they need to respire (breathe). The Oil will smother them if
the coverage has been complete. Horticultural Oil may also be called
"Narrow-range" or "Superior" Oil. This technique, is relatively safe and
has minimal adverse environmental impact. AdditionallyIt's important to
realize that most control measures are only effective at certain stages
of a pests life cycle. Oil is most effective during dormancy, at other
times the effect may be negligible.</div>
<div>
</div>
<div>
For Deciduous
Trees, spraying in the Dormant season has many benefits: The days are
cooler and moister, when sprays are less phytotoxic (harmful to
plants). The elements of the tree most likely to suffer damage (leaves,
blossoms, new shoots etc.) are safely out of the way. Bees, and other
pollinators are relatively safe.</div>
<div>
<br />
For School Orchards that
have Citrus trees, Columbus Day weekend would be a safe time to use
Horticultural Oil spray. You don't want to do it any later in the year,
and be sure that the trees are well watered before any spray operation.
<i><b>If they have been a problem;</b></i> this treatment will help control Scale, Aphid, White Fly and other soft bodied insects that overwinter in the tree.</div>
<div>

<b>A - "Keeping it simple!"</b></div>
<div>
</div>
<div style="text-align: left;">
When harvests have been completed, remove all fruit from the Deciduous Trees and rake up all; leaves, fallen fruit, and weeds. </div>
<div style="text-align: left;">
Send all the orchard waste for composting.</div>
<div style="text-align: left;">
</div>
<div style="text-align: left;">
<b>B - "More in Depth:"</b> </div>
<div style="text-align: left;">
</div>
<div style="text-align: left;">
Many pests "over-winter" in the fallen fruit and fruit left on the trees. The fruit left on the trees are called <i>"mummies."</i>
It's best to have these professionally composed, so that the usually
higher temperatures obtained can kill all of the pest larvae, bacteria
and fungi. If the tree has been very healthy, without a lot of disease
on the leaves, then composting leaves in the garden is fine. If not, put
the leaves in with the fruit for the community composting operation. </div>
<div style="text-align: left;">
Accumulated
leaves and weeds are a favored spot for pests to spend the winter, in
their own state of dormancy. In the Spring they would be ready for
another life cycle..... unless of course they've been composted !! </div>
<div style="text-align: left;">
If you have composted leaves or other clean mulch, this would be a good time to spread a fresh layer under the tree.</div>
<div style="text-align: left;">
</div>
<div style="text-align: left;">
<b>C - "What else can we do?"</b></div>
<div style="text-align: left;">

Next year, do the same thing. Mulching is a technique for covering the root area of Trees with a protective material.<br /><br />This helps retain water, reducing water loss by up to 30%. Mulch also supresses weeds, which compete with young trees for nutrients and water. Organic Mulches also slowly add organic material to the soil and encourage beneficial soil organisms.<br /><br />Coarse wood chips make excellent mulch, when applied properly. Most cities offer free mulch, from their tree trimming and maintenance operations. Call, and get a load delivered. This Mulch tends to derive from many varieties of trees, rather than the single source you usually find in purchased bags. Variety is better. Although some Mulches are considered Allelopathic (like Black Walnut Eucalyptus etc. "can kill plants") all of the coarse wood chip mulches, applied properly, will be beneficial to your trees. You want coarse material (chips, not sawdust!) so that air can penetrate, and it can dry out and not support mold or fungi.MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-39096732873003108632008-03-07T18:55:00.000-08:002015-03-26T15:30:32.119-07:00Watering your Fruit TreesWatering once or twice a week is best. Here are the guidelines for watering based on region and tree age.<br />
<br />
<br />
<span style="font-size: 180%; font-weight: bold;">Basic Summer Watering Chart: </span><span style="font-size: large;">(80% of these rates for coastal schools) </span><span style="font-size: 180%; font-weight: bold;"><br /></span><br />
▶ 1st year trees: 10 gallons per week. <br />
▶ 4’ diameter canopy: 15 gallons per week. <br />
▶ 5’ diameter canopy: 25 gallons per week<br />
▶ 6’ diameter canopy: 30 gallons per week<br />
▶ 7’ diameter canopy: 45 gallons per week <br />
▶ 10’ diameter canopy: 80 gallons per week <br />
<br />
<span style="color: #330033; font-size: 130%; font-weight: bold;">How we got those numbers: </span><br />
<span style="font-style: italic;">Inland Counties:</span> Requirement in Gallons/week is about equal to canopy area. Example: A canopy with a 4ft diameter has an area of about 12.5 ft^2. (If you need a review on how this works, please see the math teacher down the hall). Thus this tree wants about 12 gallons/week. Add 20% if you are watering in the day time for evaporation loss.<br />
<br />
<span style="font-style: italic;">Coastal Counties:</span> Follow the same formula as inland, but use only 80% of the water. Example: A tree with a 4ft canopy diameter will want 80% of 12.5 gallons or about 10 gallons. Add 20% if you are watering in the day time for evaporation loss.<br />
<span style="font-size: 130%;"><br /></span><span style="font-size: 130%; font-weight: bold;">Spring and Fall:</span><br />
50%-80% of the summer water amount.<br />
If a fall fruit has already harvested, reduce down to 25-50%.<br />
<br />
Check the soil under the mulch several times before leaving for Summer. Adjust water quantity up or down so that between waterings the soil is not wet enough to stain your palm, or dry as dust.<br />
<br />
Don't let water stand against the trunk.... not good!<br />
<span style="font-size: 180%;"><br /></span><span style="font-size: 180%;"><span style="font-weight: bold;">Fine tuning your watering amounts:</span></span><br />
You can check the moisture level with a metal probe into the soil (e.g. straightened hanger). It should go down about a foot for your new trees. That means there is enough water at the root level. If it's too dry or too wet just prior to your irrigation, adjust the amount up or down by a gallon.<br />
If the soil is Sandy or Sandy Loam, divide the total amount of water in two, and water twice per week. If the soil is heavy clay, once per week for the entire amount should be fine.MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-66866974464769792262008-01-30T08:49:00.000-08:002011-03-06T21:58:40.729-08:00High Density Planting for the Schoolyard<iframe title="YouTube video player" width="660" height="525" src="http://www.youtube.com/embed/lo3_u08CwdY" frameborder="0" allowfullscreen></iframe>MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-78605990478416388562008-01-13T22:25:00.000-08:002014-04-20T12:32:54.449-07:00Thinning the Fruit (April - June)<b>Need thinning:</b>

Control their farmersAphids suck the juice from tree leaves. Ants love the sweet excretions of the aphids. Therefore ants farm and protect these pests for their own enjoyment. <br />
<br />
The most effective strategy for getting the aphid population in check is to stop their farmers with a sticky physical barrier on the trunk called Tanglefoot. <br />
<br />
Do not apply it directly to the bark. We recommend using 4” wide wrap of waterproof paper or tape on the trunk
of the tree and applying Tree Tanglefoot over the wrap. Tree Tanglefoot will remain sticky
longer when applied on top of a surface resistant to oil. Check the video below for the best way to apply the bands to larger or irregular trunks. <br /><br />Apply Tree Tanglefoot Insect barrier in a uniform fashion. It can be applied in a heavy or light coat. Heavy coats are approximately 3” wide and 3/32” thick. A heavy coat is used when the insects to kept from the tree foliage are large or numerous, or when there is little time available to maintain the band. Light coats are 3” wide and 1/16” thick. A light coat is good as a general barrier against smaller or less numerous insects, or when the band can be maintained regularly.<br /><br />Be certain that the ants do not have an alternate route for climbing the tree such as low branches that touch the ground or a sign post that touches the branches. <br /><br />Generally, Tree Tanglefoot will remain sticky and effective until it is
covered with insects, dust or other debris. A build-up of debris or
insects will create a bridge for other insect to cross. This debris
requires removal and possible re-application in spots. If an area is
unusually dusty or the surface of the barrier is stiffened, Tree
Tanglefoot can be rubbed around to expose a new sticky layer
beneath. Remove bands at end of season.<br />

It's a very important part of having an orchard, a skill that's fun to learn and very satisfying to practice. Courses are given in many public gardens or arboretums. The County Master Gardener Programs will also have introductory and advanced courses. The L.A. County Urban Orchard Team can put on a workshop at any school or community orchard. Common Vision has online resources as well to make it even easier. We want to help you feel empowered and informed through this great activity. Feel free to contact Common Vision with any questions.<br /><br />Winter is a good time to do very important "Maintenance" pruning, and you've probably already had some practice with the post-harvest pruning and trimming. When the trees are bare of leaves, the woody structure is more clearly visible, making pruning much easier. A primary objective of training and pruning is to develop a strong tree framework that will support fruit production. Improperly trained fruit trees generally have very upright branch angles, which result in serious limb breakage under a heavy fruit load. This significantly reduces the productivity of the tree and may greatly reduce tree life. Another goal of annual training and pruning is to remove dead, diseased, or broken limbs. Pruning is also really important to optimize fruit production, open the canopy for more light for flower bud development and optimal fruit set, flavor, and quality, as well as airflow for drying out and disease prevention.<br /><br />Are you move of a video-based learner? Most of this is also covered in <a href="http://commonvision.org/ftt/fruittreecare/fruittreecare.php?id=5438013837529689098" id="ovt1" title="UCDavis Tree Care Video with a pruning section at 36min mark.">This Pruning Video</a><br /><span style="font-weight: bold;"><br />Have a Newsletter or Worksheet with you if it helps!</span><br /><br /><span style="color: rgb(0, 0, 0);">So first things first, a diagram of a tree and terminology:</span><b style="color: rgb(0, 0, 0);"><br /><br />a)l</b><img src="https://docs.google.com/File?id=d6m8njg_9frck3hd5_b" style="color: rgb(0, 0, 0); float: left; height: 148px; margin-left: 0pt; margin-right: 1em; width: 361px;" /><b><span style="color: rgb(0, 0, 0);">eaf buds </span><br /><span style="color: rgb(0, 0, 0);">b)flowerbuds </span><br /><span style="color: rgb(0, 0, 0);">c)spur </span><br /><span style="color: rgb(0, 0, 0);">d)short shoot </span><br /><span style="color: rgb(0, 0, 0);">e)long shoot </span><br /><span style="color: rgb(0, 0, 0);">t)terminal bud</span><br /><br /></b><br /><br /><br /><br /><img src="https://docs.google.com/File?id=ddbh6d8r_138dsgdqs83_b" style="float: left; height: 300px; margin-left: 0pt; margin-right: 1em; width: 300px;" /><b><span style="color: rgb(204, 0, 0);"><br />Suggested Pruning Cuts<br /></span></b><br /><b><span style="color: rgb(204, 0, 0);">A.

Whorls<br /><br /></span></b><br /><br /><br /><br /><br /><br /><br />It's important that you take a moment, and be sure that you can identify this year's growth from the previous year's growth.<br /><br /><span style="font-weight: bold;">So, we'll stop for a little exercise: </span>Look at the end of this past Summer's growth. The shoot tip has a little bud on the end (that will be the start of growth this coming Summer). Run your finger back towards the trunk. The bark of the shoot is very smooth, quite green, or at least greenish brown. Soon you come to a little scar, a circumferential ridge. This is where last year's bud was. The bark now becomes somewhat rougher and browner; the shoot is a little thicker. You've now identified the transition to the previous year's growth. Actually, you can keep running your finger down and identify each year's successive growth. For fun, you can go right back to the trunk, and there you have the year your tree was planted!<br /><br /><span style="font-weight: bold;">Why is this important?</span><br />An apple tree will set its fruit on a little "Spur." Year after year the tree will produce fruit on the same little spur, maybe more than 10 years.<br />We don't want to cut this Spur, or its branch. A peach tree will set its fruit on the shoot that grew last Summer. Once it has produced a peach on that spot, it will never again produce a peach there ever! So, that's why the little exercise has practical value. We want to keep the older wood in the apple, but we continually need new wood on the peach tree...if we want peaches.<br />And remember the important rule: We don't prune the apricot in the Winter! Perhaps it's best to put a little sign on the apricot: "No Prune Zone", or perhaps Pruners in a circle with a line through them (the international No Prune sign ?).<br /><br /><br /><span style="font-weight: bold;font-size:130%;" >PRUNING: Let's review the simple approach.</span><br /><br /><img src="https://docs.google.com/File?id=ddbh6d8r_140g5j56nhh_b" style="float: right; height: 407px; margin-left: 1em; margin-right: 0pt; width: 330px;" />The following applies to all of the trees:<br />1) Prune out the Suckers. These are the very vigorously growing shoots, that come from the "Root-Stock" below the "Graft Union." Recall that's the slightly swollen area 2" to 6" above the soil level.<br /><br />2) look for any Watersprouts that may have been overlooked in your Summer pruning. These are vigorous growing shoots, not usually bigger than the width of your little finger. The bark is smooth and green and they grow straight up, without any branches. They rarely bear any fruit, and they tend to shade more important fruit bearing branches. So...cut them off, right outside of the little branch bark-collar. Remember that's the little swollen ring of bark at the beginning of each branch...where it originates from the trunk. Or where a shoot originates from a branch. Protect the "Collar," because that's where the tree will heal the pruning wound.<br /><br />3) Now that you have a good view of things, remove any branches that have broken, or are rubbing against other branches. Branches or shoots that are pointing down or towards the center of the tree (rather than growing up and outward) are very apt to cause trouble. They should also be removed...at the little "branch bark-collar" of course and make sure there are no stumps sticking out...nice cut!<br /><br />4) Try to recognize any diseased shoots or branches. Fire Blight, for example, unfortunately affects pears and to a lesser extent apples. The end of the branch may look burned or blackened, bent over, and often with the dry crumpled leaves still attached. Obviously diseased areas like this should be pruned out, removing at least 12" of healthy looking branch together with the diseased section.<br /><br />Whenever you're pruning branches that don't look perfectly normal be sure to disinfect your pruners between each cut with 70% to 91% Isopropyl alcohol (drug store alcohol). Dip your pruners for a few minutes after each cut. An old tooth brush or spray bottle is also helpful for this. Also make sure your pruners are sharp!<br /><br />If your trees are 1 to 3 years old, or if they're growing slowly you can limit your pruning at this point.<br /><br />This next part is for those trees that are more than four years old, and have grown substantial structure: <br />5) Last, but equally important, is to remove some of the previous year's growth. This will protect the tree from limb breakage and from fruit setting too far out on a fragile branch. This type of pruning will also lead to larger, better quality fruit.<br /><br />Pruning a mature tree:<br />The peach and nectarine, (and the apricot, once the rainy season is over) need "heavy" pruning. 50% of the one-year old shoots should be removed, that would be every other 1-year-old. shoot...pruned! with the remaining one-year old shoots: get a good look at the whole shoot, and mentally divide it into thirds. Then remove the outermost third. So we've left a little more than 60% of 50% of the shoots. Who said there would be no math?<br /><br />There's going to be a lot of wood on the ground!<br />Years ago my instructor said, "When pruning, or thinning fruit it's best not to look down!"<br /><br />Now what about those 2-year old shoots, they're not going to bear any more fruit! Assuming that they are not needed as major branches, they should be cut back to a one-year old shoot, or near a nice bud where they can start some "new wood."<br /><br />The apple and pear trees need a lot less pruning. If they have not yet reached your target size, remove only about 10% off the ends of this past Summer's growth (remember how to identify it). This will encourage branching and more fruit spur formation.<br /><br />The pomegranate will have a lot of suckers coming from around the main trunk. Unless you want to grow the pomegranate as a "bush" (which is OK), prune these extra little trunks down to the single large one. These suckers are really accessory trunks, part of the main fruit producing tree.<br /><br />The <span style="font-weight: bold;">persimmon</span> sets its fruit on the ends of last year's grows, so don't cut off too many of this "fruiting wood."<br /><br />With all the trees; keep the tops pruned down so the trees do not exceed 8 feet in height. As we've mentioned before, this type of height pruning is best done during the Summer, when you're less likely to stimulate more rapid regrowth.MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-81596216415162610392007-03-07T11:53:00.000-08:002011-03-16T12:25:51.149-07:00Feeding Trees: Compost, Mulch, and Fertilizer<span style="font-weight: bold;">A- "Keeping it Simple!"</span><br />Generally speaking compost and mulch will provide the tree with everything it needs. <br /><br />Apply compost in March June, September. <br /><br />A March/April application of addition organic fertilizer in the first 2 years OR if the trees are deficient in nutrients is a good idea<br /><br />Look for good quality compost and/or a balanced fertilizer with micro-nutrients (see below for more). Because fertilizers vary in strength, you need to read the Label to find out how much to feed each tree.<br /><br />Trees need to be well watered before fertilizing, so water them the day before or early on the day you're going to fertilize. The dripline is where the majority of the feeder roots are sucking up nutrients (not directly around the trunk).<br /><br />First, push aside any mulch that is around the dripline of the tree. You want the compost / fertilizer on the soil. Second, spread the fertilizer in a circular band just within the radius where the branches and leaves end, not near or touching the trunk. Third, cultivate the fertilizer into the top few inches of soil (scratch it in with a toothed tool). Finally, water the entire area, to soak fertilizer into the soil and down to the roots. Replace the Mulch.<br /><br />You've done it !<br /><br /><span style="font-weight: bold;">B- "More in Depth"</span><br />Just as we do best with a balanced diet of; Fat, Protein, and Carbohydrate, the Trees do best with a balanced diet of N (Nitrogen), P (Phosphorous), and K (Potassium). That's the N-P-K, and the numbers give the percent in the bag (or box) by weight. Just as we need Vitamins and Minerals the Trees need Macro and Micro Nutrients, such as; Iron, Zinc, Sulfur, Calcium etc. Many California soils are deficient in available Iron and Zinc<br /><br />If you've got some yellow leaves, or leaves with yellow areas (chlorosis) you would do well to add some Micro-Nutrients. Particularly if using a general fertilizer of just N-P-K. If you're in a store where sales people are always, "busy" look for an Organic mixture with balanced NPK like 5-5-5.<br /><br /><span style="font-weight: bold;"> C- "But I'm 'Certified' Organic!"</span><br />Compost does the trick here. Or if your trees need a boost make sure your fertilizer is OMRI approved.MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-79091671362573335122006-03-11T17:47:00.000-08:002011-03-11T17:49:31.229-08:00Bud to Blossom to Fruit<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDexVIoGZ4jhsmp7S_ZxuCQ9e9hyphenhyphendU5y1Lf1svpFXtxxaBmppA0M4C1w9Hasnk89ptnq0eqEQCyhT7fN3qUvhmKLxvJaqNjqEiAL6qBdUS2ezRvpsAkXQ8Cg9FQS7xK4ZWttDGsIMsgPc/s1600/budtofruit.gif"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDexVIoGZ4jhsmp7S_ZxuCQ9e9hyphenhyphendU5y1Lf1svpFXtxxaBmppA0M4C1w9Hasnk89ptnq0eqEQCyhT7fN3qUvhmKLxvJaqNjqEiAL6qBdUS2ezRvpsAkXQ8Cg9FQS7xK4ZWttDGsIMsgPc/s400/budtofruit.gif" alt="" id="BLOGGER_PHOTO_ID_5583004459444339970" border="0" /></a>MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0tag:blogger.com,1999:blog-2945588823094770909.post-9980480862743296782001-11-14T16:19:00.000-08:002012-11-14T16:19:47.128-08:00Dormancy - What's really going on<span id="internal-source-marker_0.1525275834824552" style="background-color: transparent; color: black; font-family: Verdana; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Thanksgiving has passed, the leaves have dropped, the trees are bare, and the Orchard is entering "Dormancy." </span><br /><span style="background-color: transparent; color: black; font-family: Verdana; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">AND...
beneath the bark all sorts of things are going on, and the trees are
(with chemical reactions) "counting" the days to Spring! Photo-receptors
near the leaf scars are noting the ratio between dark hours and light
hours (the "photo-period") that's how the tree will know exactly when
Spring arrives. All the Enzyme systems that drive the leaf and flower
making machinery are on "idle". As the temperature rises the chemical
"gears" will start to whir. The Hormone that signaled the leaves to
drop, is now the "brake", keeping everything dormant. When the
temperature is cold, the dormancy Hormone will degrade (get used up).
When the right number of hours of "chill" have been accumulated (those
are the "Chill Hours" on your tree label. Check it out!,) the brake
comes off. With the dormancy hormone is gone, the temperature and
photo-period will be in control, so watch the Orchard for the "March
Magic." (check the bottom of the email * for more detail)</span><br /><span style="background-color: transparent; color: black; font-family: Verdana; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">The
trees have been storing up water and sugars that will fuel that first
big push of flowers and leaves. (Then that sap begins to flow in Spring,
think "Maple Syrup.") </span><br /><span style="background-color: transparent; color: black; font-family: Verdana; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> </span><br /><span style="background-color: transparent; color: black; font-family: Verdana; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Though
looking very quiet and serene, the trees keep working and we've got
some Orchard Activities that will have a major effect on how the trees
function in the coming year, and how bountiful a harvest you'll enjoy.
By doing these activities you'll also understand a lot more about your
Orchard. Have fun!</span>MichaelCommonVisionhttp://www.blogger.com/profile/00573852240204329468noreply@blogger.com0
