|What are the general guidelines for pruning plum, nectarine and citrus trees?|
|Citrus trees rarely need pruning. In fact, it's better to leave branches low on the tree because the foliage protects the sensitive bark from sunburn. Sunburned bark cracks, allowing pests and diseases to enter. Prune to remove broken or problem branches in early spring, after the last frost. Don't prune in summer.
Your other fruit trees should be pruned and trained to optimize fruit production. Explaining the process is more extensive than space allows in this forum so I'll direct you to a publication from UC Davis cooperative extension that will walk you through the process. It has written directions plus some line drawings. Hope you find this information helpful: http://ucce.ucdavis.edu/files/...
