Sweet potatoes

[roitelet]

I have Sweet Potatoes growing well in the Poly Tunnel. Should I feed them and if so what with.

Thanks

We are doing sweet potatoes this year as well (its our first year so experimenting). The four plants we have planted outside have not grown well at all, presumably because not warm enough. We have two in the polytunnel that are thriving, at least the vines are.

I'll be following this thread as I'd like to know if they need feeding too.

Sweet potatoes don't start producing tubers until pretty late, so for now, and until about mid-August, I would feed them with a high nitrogen liquid feed, to encourage plenty of leafy growth.
Then after mid-August, switch to a high potassium feed (tomato feed is fine). Ideally you want one high in phosphorus as well as potassium. If you really wanted to, you could buy some specialist potato fertilizer, which is lower nitrogen but high phosphorus and potassium. But for good tubers, of pretty much any tuberous vegetable, lower nitrogen but high potassium is most important, and phosphorus is secondary.

Thanks Ameno, I have got some Potato Fertilizer so I will use that.

Just found this. Curing Sweet potatoes. https://morningchores.com/curing-sweet-potatoes/ Didn’t know that they had to be cured to keep well and develop flavor.

Hope all you Sweet potato growers find it useful.
