I’ve been starting my sweet potatoes from sprouted old roots rather than starting from new potatoes for quite a few years, now. It’s a close to fool-proof method. Here are 25 sprouts in a soil box. I removed the sprouts from the mother plants and cut them into handleable sections before shoving them into the soil.
Note that many of the sprouts have already leafed out while still attached to the mother root. Some, however, are just pink sprouts that will quickly green up in their new home.
To make sure the starts keep warm and moist I constructed a very simple cover – just a clear plastic bag set upon some PVC tubing. This cover will hold in heat at night and let the sunshine coming through the windows heat the box up a lot warmer than it would be without a covering.
The setup is easy and easy to take care of. Hopefully, I’ll have at least 17 good starts ready to plant in a garden bed at the end of May.
