Tomato Seeds Not Germinating
I planted tomato seeds in flats about 3 weeks ago and I haven't seen any sprouts in some of them yet. I have them in my greenhouse outside (a cold greenhouse). Today, my impatience got the best of me so I started moving a little soil away to see if there were any signs of life. I didn't see anything; not a sprout, not a seed, nothing! Where did they go????
Here's what I've planted and what has germinated:
Beefsteak: They are about 1" tall
Grape: They are about 1" tall
Rutgers: One flat came up beautifully, the other, nothing
Large Cherry: Nothing
Any advice or ideas on what I've done wrong?
Maybe it's too cold in my greenhouse at night. This is my first round at using a greenhouse so this may be my year to learn the hard way!!!!
