Q: Can I plant some lettuce now?
A: Lettuce is very easy to grow but is best grown here in the coolest months of the year (December – February). If you want to grow from seed, be sure to plant them shallow. Start out with moist soil, but not wet. For Romaine try Parris Island Cos or Outredgeous. Suggestions for loose leaf are Simpson types, Salad Bowl, Red Sails, and New Red Fire. If you prefer a butterhead then plant Ermosa, Tom Thumb, Bibb or Buttercrunch. By the way, lettuce can easily be grown hydroponically in a green house with very limited space. http://edis.ifas.ufl.edu/hs184
