Once the tree sets fruit it will slow way down. 

My reeds set pretty much every flower.  They drop most but still hold 2-3X more than they can.  I go in around July or august and do some thinning. When they are young they will drop the fruits early(this time next year) if you dont thin down to the proper fruit load.



Man, that is just crazy.  Here's some great advice regarding thinning and the ones to choose and the ones to let stay.  Agree with this?

No question, avos shed a lot of fruit, especially those fruitlets set late in the bloom period, when competition for energy and water arises between developing fruitlets and new shoot growth. Bigger, older, earlier-set fruit have an advantage. With an avocado, itís last hired, first fired. If the late-set fruit is all self pollinated because the pollen partner is done blooming, that fruit will drop at a much higher rate than the more established (and possibly cross-pollinated) fruit. It will drop not because it is self-pollinated, but because itís smaller, and the tree has less invested in it. If this fact is overlooked, then analyzing the dropped fruit for paternity would skew your impression of the need for cross-pollination.

Newer, more nuanced DNA research has shown no correlation between cross-pollination and yield.

I just let it drop what it wants then come in mid to late summer and remove more when they are like golf ball size.  At that point the tree has already ditched the losers.  Right now when they are pea sized, I might go shake the tree a little and speed things up and knock half of them off.  What I dont want is the tree to put a ton of energy into fruit thats not going to be there for the long haul.

I'm surprised you let them get up to golf ball size.  Peach growers and that includes me thin their trees up to 40% when the fruit is pea size. 

Fruit on the left is from a peach growing friend.  Betcha can't guess who grew the wimp on the right.  ;D  Same variety.

You can shake the tree and make it drop a lot of fruit but its still too much to thin by hand at pea size.  Look how many fruit there are.  Thats just a tiny branch.  Easier to just wait a couple months and let the tree do its own thinning and then decide if it needs more.  By the time they are golf balls, the tree will have already shed 99% of the fruit.

Yep, that would be a PITA.  Friend has some cheap labor which helps. 

Nice profile on that Reed Seanny.

....and this is not.   :(

One 10' long trunk out of 3 larger ones started tanking over the last 2 days.  It started right after I drenched it with a lot of rainwater.   If the flowers don't make am thinking about taking it down to a stub.  Will tie it up to the rafters for now.  It's about 1.5" thick and healthy with some woodiness going on.

Thoughts?



Pinkerton grafts/branches in the separate bed on the right, one cleft and one side veneer.

One strategy is to reduce height by 1 node per year.
If you cut 4' off today, next year you cut 1 node down from today's cut.

I'm going a different route.
I'll put shade cloth on an umbrella. Tie umbrella to leader.
I'll remove new leaves on any branches that grow straight up. Then cut it off in Winter.
Hope to maintain my Reed at 7.5'

I took 5' off and braced the remaining 7' with a board under a branch running to the ground.  It'll branch like crazy below that cut.

Heres some pics of a couple baby trees I planted these 1.5 years ago.  They are already 6-8ft tall. If I had to redo it, I would have trained all my reed trees on a 10ft T post.

If you want to slow down your Reed by defoliating it which deprives it of food and it's getting you what you want, OK.  My Reed is also very vigorous but I control that with pruning, an application or two of Bonzi, a plant growth regulator, which if done during mid bloom increases fruit set and size according to field studies.  A tree without fruit will be vigorous with more vegetation.

My Reed is now in mid bloom and 2 months late.  At least the bees and other pollinators finally found it.  We had a helluva flush of wildflowers in Texas this spring which I think side tracked pollinators.  I also think my two applications of potassium sulphate and Solubor helped initiate the blooming response earlier this year.  Here it is last month.  It has hit the top of the greenhouse roof since then and is wider.  3 leaders/trunks, about 3" in girth, after freezing back to a stub Jan. 2018.


Hi Mark, I'm curious where you source your "Bonzi" (is it Paclobutrazol)?  I looked for some a while back for my side-yard project, but I couldn't find an accessible source for a suburban consumer.

I don't remember where I got it, probably ebay.  I've seen it under the PGR category at ag vendor sites.  Google is your friend.  There's quite a few field studies out there on its application.  http://www.avocadosource.com/WAC2/WAC2_p227.pdf

It really helps to shorten leggy mangos too.

This one is really packed with some good info for you commercial growers.  http://ir4.rutgers.edu/FoodUse/PerfData/3280.pdf
