We had a very mild winter in Mississippi and I set out Broccoli and potatoes in raised beds on  Febuary 24 and set out 40 tomato plants on March 24. I set out 24 Better Boys, 6 Mountain Springs, 2 Big Beefs and 8 Super Marzano Hybrids. This tomato is a Roma tomato that is great in salsa. (My son Jeff makes great salsa)
I also set out greenbeans, squash and peppers. Below are a few Pictures of the garden.
