A lot of people ask me when I can start planting. Seed starting, direct sowing, transplanting, etc., etc. Here's a timeline that gives a basic guideline for NYC. It's not perfect nor are these dates absolute, but a good place to start. If I were to make some edits, I'd say that the early indoor seed starting window could be moved later. I still encourage people to start by March 1, but if starting a bit later...still go for it.
