I planted sweet potato vines in containers last summer (both the chartreuse and dark purple ones). When I took out the plants for the winter, they had grown banana-sized tubers. Could I have over-wintered these and planted them in the spring? If so, how would I do it.
Believe it or not the sweet potato vine tubers are actually edible. The taste is a cross between a regular potato and sweet potato! This beautiful vine has grown quickly in popularity for its fast growing habit and lush foliage. Yes, you can store the tubers for next spring’s planting. In the fall simply remove all foliage from the tuber, wash off any soil and let the tuber dry thoroughly for about 24 hours. After it dries, store the tuber in dry peat moss and keep in a dark area that maintains a steady temperature between 50 and 60 degrees. Next spring, remove the tuber from the peat and cut it into smaller pieces or plant whole in fresh potting soil and start watering. Place in a sunny area and in no time at all you will have lush green or purple growth!
