We're going to have a cooler than normal spring so you can still plant cool weather crops - kale, cabbage, lettuces, etc.
And last frost for me is 4/15, probably similar for you so no, you aren't too late to do the regular hot weather veggies, they can't even go out yet.
I am interested if anyone responds about the pruning, the plums did bloom late this year so are still alive and need some serious pruning along with the peaches & nectarines.
