Tomato Seedlings Dying

by Jack Jarvis
(Lebanon, Tennessee)

My seedlings are about two inches tall. I have transplanted from the seed flat to 2x2s and 3 days later they are dying one by one. When I was pulling the seedlings from the flat I saw that the roots weren’t as good and big or as many as I was expecting. Most of the seedlings only had one thin root. Please advise.
