Hannah,
I don't know what you start your
seeds in--I use 3-inch Jiffy pots (Wal Mart has them). I always put at least 2 (you could put as many as 3)
seeds in each, thereby ensuring I will likely get at least one healthy
plant in each pot (I've rarely had a totally empty peat pot
I already have Roma tomato
seedlings up. I planted 2
seeds each in 14 peat pots and had both
seeds in 11 of the 14 pots germinate. The other 3 have 1 each. Now I have to do the part I alway just hate--pull out the very healthy extras from all the pots with 2 tomatoes in them
Good luck on your planting.
