Help needed with growing sweet potatoes

Hi there

I grew sweet potatoes this year in them grow bags that you can buy to grow normal potatoes in. The ones about 24 inches square and about 3-4 feet high .

I had one or two decent size potatoes but they seem to be all curled up. Is this because there not enough room in the bags? I also had loads of really small stringy potatoes that look like they couldn't expand.

Am I better off growing them in large pots?

Thanks

 

if you could put your location @tweacle we could help more, I didn`t think sweet potatoes grew well in our U.K. ? climate, never looked into it much though.

 

Its just not warm enough for long enough in the UK ? Maybe it works in a polytunnel or large greenhouse thats heated in the spring and autumn.......

 

yeah sorry I was in the UK. I may try growing them next year in the greenhouse and see what happens.

 

There are supposed to be varieties that are suitable to grow in the UK.
I've never tried them myself so reserve judgement, but I tend to think you will always be struggling to provide enough heat and humidity for long enough.

If you have ever tried water melons?
Its a similar problem, cold nights mainly.
