Soil should be warm enough by now down there. Can you walk in the garden bare foot comfortably? Then it's time to plant out. If leary, plant out about 1/2 of them. Take 1/2 doz, transplant into 5 gal containers and leave them inside. Check soil pH, Parts of FLA seem to have a high alkaline soil, you might want to buy some loam or adjust soil ph. Another thought, Since you are on the beach, your natural soil might have a lot of salt in it, that can kill plants. Might try a few in 5 gal buckets with some good loam, Bury buckets almost to the rim, this helps keep the soil cooler and reduces evaporation.. Byron
