Are You Pruning Too Much?

Kio has taken some flack from arborists claiming that heavy pruning is bad:

“I bought a lot of fruit trees and bushes and plant cuttings and I’ve been planting my butt off to get a nice decent sized beginning food forest started. I’ve got a persimmon, some figs, a pineapple guava, lots of blueberries and a few other things and I’m hoping to get some more in March. I live in North FL, near __________, and I’ve always loved the resources you put out, I’ve bought almost every one of your ebooks and read them and I’ve found most of your methods to work really well.

I watched your video today about pruning, and had been hearing from other gardening and homesteader friends that taking such a heavy handed approach to pruning is great for starting woody plants like fruit trees and bushes.

Note: here is the video referenced:

I did that to what I planted this past weekend and I’m planning on trying my hand at making a few cuttings. I shared some pictures on a gardening community discord I’m on… And a few more traditional gardeners were very upset, naturally, with me. One of them claimed to be an arborist with 20 years of experience and said something along the lines of “Needing to understand what happens when you take such an aggressive approach and what the outcomes are.” And that in his experience it causes more harm than good, and creates scenarios where excessive management is required and increases the amount of “plant stress.” And another person said something about them learning similar things and that lopping off “the entire canopy” was taught to be a bad thing during his time at university studying plant science.

I liked the video and I’ve found most of your methods to work very well as I’ve said, but I also tend to be a skeptical person and rather scientifically inclined, so I’m curious if you can offer any more information in this regard about the claims and things these other gardeners have said. I also plan on purchasing those pruning books you recommended. The gardeners provided a few sources for some of their claims, including some forestry sources on proper pruning, and I unfortunately can’t help but be even more skeptical, as modern agriculture practices have done a lot of damage to the Earth.”

Good questions.

First of all, I am not an expert on pruning – I am just a backyard fruit-tree growing enthusiast with a lot of head knowledge and some experience. I’ve also made observations on what happens when you prune, as I wrote in the Survival Gardening Newsletter this week:

It was a steamy tropical afternoon as I trudged up the long, rocky road to our house in the Caribbean jungle.

Lose Your Fear of Pruning

Having seen how much trees can take, I have lost my fear of pruning. Most of my fruit trees I want to keep small so they will fit into my garden rows, so I prune brutally, looking for a vase shape.

I have seen avocado trees cut down to stumps in order to reinvigorate them. I have seen mulberry trees chainsawed to the ground every few years so they don’t get too tall.

Also, I usually propagate a lot of my own trees. If I kill one through pruning, who cares? I have plenty of backups.

People are way, way too tentative. I haven’t actually killed a tree with pruning yet. If you cut them at this time of year while they are dormant, they seem to hardly notice. And despite all the lectures people get from extension offices about “not topping crepe myrtles,” for example, I see lots and lots of old crepe myrtle trees that have been topped a zillion times without dying and they look just fine in bloom.

Just consider your goals: are you trying to keep a tree tiny? Are you pruning for shape? Are you simply a psychopath? Do you want fruit this year – or are you unconcerned with fruit for now?

If I want big trees, I just let them grow. I don’t prune every tree. If you start seedling trees and want them to grow into big shade trees, great – let them grow. Pruning may mean you have to maintain them more and if you won’t want to bother, fine.

I saw the peach trees growing at the farm of a former UF scientist and he had cut all their trunks at 18″ or so above the ground and trained them into vase shapes. The fruit got lots of sun and was easy to pick. Alternately, I have seen big peach trees that have never been cut and they’re a tall mess of branches without the ease of harvest.

If you want a more moderate approach to pruning, Steven Edholm’s video where he talks about his fruit tree pruning is quite good:
