Good to know that we didn't pull them early enough. Our vines never died, so we kept not pulling the tubers, because we read to leave them until the leaves started yellowing. We saw the tops of the tubers, which looked very small, popping through the mulch, so we kept waiting. We finally decided to dig one up, and realized that the tiny tops of the tubers ballooned out into ridiculously huge sweet potatoes below ground. So we figured that we left them too long!
If you bury the vines, they will produce more tubers? Is there anything more to this technique? I did wonder when some of the vines had rooted and had 12"-18" long thick red roots, but sonce they had not bulbed out into round tubers, I figured they would not do anything more.
I may try overwintering some slips in a pot, then, as it sounds like it may work well. Idk, we'll see if I can find a good place inside to keep a pot full of. vines with two toddlers in the house....
Thank you!
