"But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel."-- 1 Timothy 5:8
Abigayle, add a LOT of sand (construction sand is best for our soil) to your mix. I grow them here near Rome and grew them in the spring in Florida - we planted 2/14 and harvested in June so heat shouldn't be an issue for you.
Great advice from everyone, thanks. This year, we put some plastic down on each side of the sweet potato slips. I think it kept too much water out. Thor had put in good irrigation systems in the gardens and raised beds, but I don't think we got enough water, with the drought, for the soil under the plastic to form potatoes of any size. We got some, eating the rest up this month. Those formed right under the slips. Still have not found any horseradish! Had to buy some at the store to make a tonic and back when I made my Bloody Mary Mix. Which was excellent by the way....brag, brag, brag....
