Yes!!
Most of us are scared about pruning our trees. I wrote into Mid American Gardener some 6-7 years ago and a Professor Emeritus answered my email question about pruning on the air.
To Sum:
1) Prune off all Dead wood (6-8 inches into the new wood IF the whole limb isn't dead)
2) Open up the inside for sunlight and airflow
3) Prune NO MORE THAN 30% LIVE WOOD/year
4) Prune during dormancy, end of dead of winter
5) Remove waterspouts (growing out of the main trunk) and suckers (growing from the base of the tree)
6) Choose between two rubbing branches. Prune one off and keep the other.
I finally pruned my drawf Magnolia this year. They don't like pruning and I left two large limbs that are growing next to each other. In 2023 I will choose one of them to prune off. It won't be more than 10% of the tree and won't harm it. Seems like it didn't mind the pruning bc I got loads of flowers and it has leafed out nicely.
NOTE: If the tree hasn't been properly pruned you may NOT want to take all of the
waterspouts.
I had to be careful with my pear tree. It tried to die from blight a few years ago. I pruned back the dead/dying branches and it recovered.
THEN, it overcompensated and grew 10 ft waterspouts, right from the center.
I didn't take all of them this year, even though they were LOADED with blossoms.
For Me, pruning time means end of February/beginning of March, while the tree is in dormancy AND while the insects that predate are still dormant, too.
In nature, these trees are eaten upon by animals during the winter and they have grown to tolerate this.
Without pruning, the energy goes into the leaves and the tree will die prematurely.
This video is pretty good.
