Would you defoliate these?

If you're going to argue the benefits of defoliation then photosynthesis is definitely not something that's going to benefit from defoliation. Are you trying to imply that defoliation is beneficial to photosynthesis?
Absolutely

Oh, You just go off of the Bro-science . I gotchya. Why did you want me to link you to science if you don't read?
I learned from grow communities, family & friends, and a life long interest in plants in general. Not by reading scientific journals. Like 99.9% of humans since cultivation became a thing. I'm not anti-science by any means, but I'm not waiting for the green light on all of my techniques by some nerds in a lab.

edit: something sly happened here.

Pre harvest pruning and/or leaf removal is a much used practice when growing grapes, peaches, nectarines and apples. It is done to open up the trees and expose the inner fruit to the sunlight thereby increasing size and color. It can be used in grapes to increase sugar and/or pump up the size of the bunches.

Not entirely true as far as peaches and apples. Spring pruning is actually done to reduce the amount of fruit, so they have more larger ones, instead of alot of small fruit. The added light from the pruning does help the inside fruit ripen faster, but not any larger.

Apples are chemically thined at the flower stage so they will have a return bloom. If you wait until they are set then they will go into alternate bearing. The crop load of peach and grape is balanced by correct dormant pruning.

This is dependent upon which variety you are talking about. Not all varieties are biennial.

I can't comment on the weight but on the twice I've tried defoliating the plants haven't stretched near as much.

It's not difficult to see the difference and I wasn't too harsh 2,3 big leafs from the top of each branch, it's not clones so I can't be certain, the one other time was clones but there were other variables however I'm fairly sure it has some effect on the stretch phase.

There is an excellent podcast on defoliation by Rasta Jeff from Irie Seeds. I recommend a listen.


I used to remove the bottom 1/3 of plant material on each of my plants, and not do anything else. I was getting on average about 68 oz from 24 plants. Now I lolipop each plant and do a few thorough defoliations and am averaging over 100 oz. There's a lot of advantages and very few disadvantages IMO. But it has to be done correctly, at the right times and the correct amount of leaves to be removed. It takes some practice to get it right.

Ethos Genetics also has an excellent article on their website detailing how they go about it. Most large commercial growers do defoliate, and that alone should tell you something. Below is my current thread here on RIU, and I detail with pic's a lot of my defoliation thru the grow up to this point.
