I live in Massachusetts in the US, and just found out that I do, indeed, have space for planting in the giant garden that is apparently shared between the neighborhood. Is it too late to start zucchinis and watermelons? What about sauce tomatoes? I've never tried to start anything this late in the season before and am wondering if I should just go buy transplants.
ETA: According to the google machine, our last frost date is usually the end of April and first frost is in October.
