I just planted this past Wednesday the 1st. I mean I had things that could handle cooler weather out for a while (onions, cauliflower, potatoes, etc), but just put out my tomato and pepper seedlings along with corn, bean and cuke seeds. I didn't have any zuchinni at the time, but have it now and will plant when the ground dries. Still waiting a few weeks on sweet potatoes.
I wanted to get everything out because we have a could of cool nights of around 48 degrees, but looking out it seems to be nice weather coming after these 3 days of rain showers. Oh the new plants for this year are celery, sweet potatoes, couple of different tomatoes. Everything else is the normal.
