I live on the east coast.Is it too late to plant seeds for vegetables?

What zone are you in? Or what state? There is a huge difference between New England and Florida. Thanks.

East coast where????

I'm in Maine.....you'd be better off with seedlings at this point. I tried after July 1 last year and did not produce much.

You can still plant green beans from seed. It might be a bit too hot to plant crucifers (which do really well as they reach maturity in the fall). Plant lettuces but watch closely because of the heat; they will bolt easily. Radishes. Look at the seed packages for length of time from sowing to maturity, and let that guide you.

Absolutely too late. Many garden centers and discounting plants now, even with tomatoes on the vines.

If you plant anything, use seedlings. If you do plant seeds and have a later freeze time, there are some seeds you can plant. My bush beans are already putting out flowers, as are my peppers and tomatoes. Figure out how many days you have until frost or freeze and check the maturity days on the seeds and add some time to the maturity date for the germination time and probably a little extra time for a longer fruit maturity time so you get more produce.
