Sweet potato

[Bex2012]

So a really dumb question, if I can root the vines from my two sweet potato plants, and pot them up, will they (in theory anyway) make more tubers next year?

[Jay-ell]

In theory yes. No experience doing it myself but they can grow tubers anywhere the stems put down roots

Let the tuber sprout and overwinter it like that. Doesn’t matter if it gets dry because the shoots survive off the tuber. Each slip (each shoot off the tuber) can be removed in Spring when it’s about 4-6” long and planted up to produce a vine. The attached is the harvest I got from one slip/vine last year. (Again, I have the weather!)
I let the vine spread and had a lot of pencil thick roots throughout the bed and the harvest came from the point where the vine was planted. This year I’m experimenting with the vines growing vertically (third photo), the theory being that all the energy will go into the tubers to be harvested. We’ll See!

Thank you both, I might try both ways and see what happens! I know one plant has made a tuber, not sure about the other one. However they do have loads of foliage i can utilise.

That’s what I have done, I just took cutting from the vines that are growing at the moment and rooted them in a glass of water.

I had a quick furlte today. I've got at least one tuber off the 6 plants. Might not be big but it felt bigger than the pencil sized roots I had last time.

Problem is if it's only one (or one per variety - there's three varieties) do I eat it or propagate from it?

What a useful thread.
I’m going to take some cuttings and try over wintering them for next years crop.
Thanks to all of you for the idea/tips.

Could you eat half and propagate from the other half?

I have a sweet potato in a glass of water. It has about 3 healthy slips and, clearly, its too late to plant them out now.
How can I overwinter them to give me a head start next year?...............or are they doomed.

^^^^ that was 25th August. Here they are now.

How big do you expect it to be? It's outdoors in Newcastle.
