Experiment: for over a year the west bed was littered with about a dozen small tree pots filled with south Tampa's "sugar sand" from when I buried a 55 gallon Water Wise Container Garden for my jaboticaba. Two weeks ago I moved them about until evenly spaced, sprigged each with "EcoFarm" sweet potato, then filled a 9 gallon bucket with rain water and added dried chicken poop, fish emulsion, trace elements and let it steep. Today each pot got a good drenching of this "nutrient soup", with the rest and the dregs going to the jaboticaba. My hopes are two fold.....abundant sweet potatoes from each pot this fall and winter, and weed control this summer from the lush aggressive vines. I love young tender sweet potato leaves added to summer salads, cooked as a summer spinach substitute, and as a portion of home made kimchi.
