Start in another 2 weeks. Last frost is May 15.

It depends on the plants - things that can stand a bit of cold can easily start going out now. I am in zone 4 and have started hardening off cole crop stuff and petunias. In my 10 day forecast there are only two nights when it will drop below 40 degrees - I assume it is warmer where you are. I often have planted out peas, broccoli, cabbage etc before now, but the snow just kept coming this year.

I'll be waiting on peppers eggplant and tomatoes for a few weeks.

In your zone? Other than cole crops if you have some, a couple of weeks anyway. Maybe 3. No need to start it until a week before plant out which is end of May for you.
