Take a sweet potatoe that is sprouting and stick toothpicks in the center so that it sits up above a glass. Fill the glass with water. The roots will grow and stem and leaves will grow up out of the potatoe.....Wen it’s about 6-8 inches long, cut it as close to the potatoe as possible and plant that end with hairy roots in dirt.....That cutting is a slip.
Some places carry them in bundles...similar to onions or strawberry plants.
Thank you, I’ll try that. Can I use sw potatoes from the grocer?
