I tend to be a late planter also. a few years ago we had 6" of snow May6th, while sometimes we have no snow after the middle of April - you just never know.
I am out of school for the summer by mid May, and don't get much done before that, but the timing is usually about perfect. Time to plant cool weather stuff and prep beds, then most of the veg garden and the dahlias go in at the very end of May.
I am behind this year with planning. I need to inventory my seeds and see what I need to order this year, and clean up my grow room in preparation for seed starting in Feb and March.
