According to an article by the Michigan State University Extension, Lettuce, peas, and spinach have a better chance at thriving early in the season. These are known as cool season veggies.
Spinach and lettuce require a soil temperature of at least 35 degrees for seed germination. Beets, carrots, peas, and radishes need a temperature at least 40 degrees.
Other plants such as corn, beans, melons, peppers, and tomatoes need warmer soil temperatures for seed germination. The optimal range is anywhere from 60-95 degrees.
