I'm just going to give you the [url=https://www.helpfulgardener.com/forum/viewtopic.php?p=136355#136355]same advice I gave Gixx in this post on Page 2 of this thread[/url].
I decided to try planting some of the not-yet-vining "slips" in sunniest of the sweet potato designated beds today. I used a sharp knife to cut off a piece of the mother potato with a cluster of sprouts -- they were near one end as Gary350 suggested. When I carefully dug that piece out of the sandy soil in the window box, I discovered they had great set of roots. I cut/dug up a few more and planted them with their little chunk of mother potato attached. I had one that I accidentally cut off of the potato but it had nice set of roots so I think it has a good start. 90/63Ã‚ÂºF and 89/64Ã‚ÂºF next couple of days, then dipping back down to 74/53Ã‚ÂºF and then 71/55Ã‚ÂºF
We're not quite there yet.
