Trimming back small trees/shrubs

I know it should be done in the fall but I think it can be done soon before it gets really warm and not damage the tree/shrub, is that true?

Thanks in advance!

not sure about shrubs but trees definitely b4 they start getting buds..

which reminds me to yell at dh for not getting the tree guy here to cut down the tree and trim the neighbors branches hanging over our pool

Re: Trimming back small trees/shrubs

I always check out specific names and "prune" on google, but in general that's a good rule of thumb. I have a weeping birch tree that must be pruned way before May because it has these bugs that attack it starting then.
