Next spring, depending how well this year’s harvest goes, I may start my own sweet potato slips from saved roots.

Most of what I read recommends that you break off the sprouts right at the potato, and root them. Is there any reason an extra-long sprout couldn’t be cut into several cuttings? If you have a single sprout 15” long, can you cut it into three or so pieces to root? Or is something special about the basal tissue?

Considering how easily the vines root even on barely-moist soil, I can’t imagine why you couldn’t.
