Re-used half of an otherwise-useless Tumbleweed composter. Turned it into a wicking bed, filled with a mix of potting mix, vermiculite, compost, soaked fine coir, Organic Xtra. The greenery was allowed to grow at will and trained up an existing trellis in a very sunny spot.
It's quite deep, around a metre. The tubers though were all nestled in the top 6-10 inches. Roots went all the way down but no tubers down in the depths.
After 9 months in the pot, the moment of truth:
Total harvest weight 3.7kgs; largest individual 1.4kgs.
"Sweet Potato 'Hawaiian Sunshine'
"Produces large tubers with an off-white skin and purple flesh. It has a drier flesh than Beauregard. It is an excellent source of purple pigments, called anthocyanins, up to 150% more than blueberries. These pigments have been linked to fighting cancer, aging, hypertension and neurological diseases, inflammation, diabetes and bacterial infections. Sweet potatoes are vining plants with attractive lobed leaves, pink morning-glory type flowers and tuberous roots. They do best in areas that are frost-free for at least 5 months with warm days and nights. In cooler areas wait for the beginning of the warm weather to plant. In subtropical and tropical areas sweet potato can be planted all year round."
Are we chuffed? You bet!
