Transplanting mature fruit trees
Hi, I have a dozen fruit trees I can get from a relative. Mostly peach trees, some pear, and a couple fig. They largest are about 4" or less. I have a machine on site so digging out to any root ball size is easy. I have a good guide to root ball size depending on diameter, etc. Since this will be performed at the end of April, I want to know what I can do to help these guys out the best to deal with the stress since it's not the most ideal time to do this. Bigger root ball than what is required?
Transport with large root ball then when planting loosen most of the original soil off?
What should I add to the soil they are going in?
Water daily? Morning and night?
Also looking to eventually train them into an espalier/wall design. Is it ok to prune a few front and back branches now or wait till late fall when leaves are all off to do that. Rule of thumb for pruning no less than 1/3 of the tree at once in effect?
