I am getting ready to put tomatoes out that I started inside. Also will plant sweet peppers, beans, winter squash and summer squash. I am in zone 4 and it does get down to about -30F some years, but the accuweather 15 day extended forcast shows warm temperatures for the next 15 days. It can snow into June and rarely early July, but I am going to go for it now.
I will keep my fingers crossed that extended forecast is right!
