No, not exactly. What I am saying is that the prunus species are sensitive.
The example I show is a dissected peach tree sample of what I recognize as a
proper cut. So, the more you prune, the bigger the pruning cut, the more
parenchyma cells that die. Trees only store starch in living cells. The
less parenchyma cells that less places the tree has to store energy in the
form of starch to be later changed into glucose for the following:
1. metabolism
2. reproduction
3. growth
4. defense (big one)

Improper pruning of a peach tree can be the end of the tree. Apple on the
other hand, is a very forgiving tree.
A peach tree has what is known as short-life disease. This is part of it.
Fine pruning on a regular basis seems to be ok. I.e., if correct cuts are
made.
This first thing I would suggest to anyone attempting to prune a woody
plant, is this book.

You could buy it, use a library or buy it, read it, donate it to your
church. Just a suggestion.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

Are you saying that is why the trees get peach leaf curl?
