Annual pruning of roses is done in early spring just before leaves appear. (leaf buds visibly swell) There are videos on pruning fruit trees and roses. It's a good idea to review several as I've seen videos that were sketchy in the advice given. The links below are to articles on rose pruning and cherry trees. It helps to know what type of rose and cherry that you have. Write back if you have more questions. https://www.gardeningknowhow.com/edible/fruits/cherry/cherry-tree-pruning.htm
