Hello I have a seasonal lawn customer who is requesting a estimate for limbing up two Bradford / cleveland pair trees and a out of control peach tree. The Bradfords I normally stay away from because of the splitting issues. but was wondering if just limbing up thumb sized suckers that have grown down about a foot on the main trunk below the main branches would affect anything? And her out of control peach tree is about 20-22 foot across and taking over her yard and wanting me to cut it back to about 12-15. Would this kill the tree to take that much at a time? I know nothing about fruit trees so any help would be appreciated thanks.
