I had 2 pots that I started some old tomato seeds in 3 -4 weeks ago. A few days ago I tried moving the seedlings from one of the pots to give them room. The transplanted ones all died. I have the 2nd pot with many seedlings. Should I leave them crowded in that pot til its warm enough to put them into my raised beds or try again to separate them. I’m in connecticut, it’s still not warm here yet, tho I am setting the plants outside every day. I’ve never grown seedlings before:(. Any suggestions greatly appreciated. Thanks.
