I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
The majority of pruning on those pears should be in late winter. However they really need very little pruning. Lots of pruning and fertilizing promote excessive growth and can make the tree more susceptible to some diseases such a fire blight.
Red maple also needs little if any pruning and the best time to do so would be in late winter. When a red maple is young some pruning can help remove narrow branch angles to promote wider branching and a stronger tree down the line.
Thanks for the question. Please stop in again soon!
