interesting .... I take it you cant stick an lidl sweet potato in the jar and keep it warm and let it do its thing ?......
/yours bookmarking this !
Yes you can ..and they will sprout slips but ..the problem is that it's a semi tropical plant and the ones in the shops tend to be grown in hotter climates than we have in the UK .. there are varieties that are bred for cooler climates and it is these that you need to either buy a tuber or some slips from them.

I'm going to have far more slips than I can use at the rate they are developing so if anyone wants a couple in a week or two to have a go then let me know. Two slips to a potato growing bag seems to be the recommended planting .. and the vines are very vigorous they will overflow and will try and root on the ground around the container they are in.

They need a fairly loose, well drained, compost to grow well and they thrive on heat...so North of Watford be warned .. you might need to have them in a greenhouse or poytunnel like Dani ...

Sweet Potato Update

Having cleared some room in the poly tunnel Stan decided to move the sweet potatoes away from the ends where we had just tucked the pots in.
The first one was hard to lift. In the ground under the pot ! We left the others where they were.

Good to see, our slips were delivered very late this year but they seem to be doing ok. It has been a good year for melons though as we are talking tropical plantsl got about eight good size ones.

Stupidly I didn’t realise you need to pollinate melons so we have only three.
We shall try to cultivate our own slips for next year.

You should be able to start slips from the sweet potatoes you have grown before summer is out .. if you then plant the slips up in pots they will overwinter in almost dormant state (has to be frost free though as they are very tender) and will take off like the proverbial when you plant them on in spring.

I am very impressed with your crop so far ... if that is under the pot you must have a stunning crop above .. I hope mine are doing as well

(alternatively .. if you would like some ready rooted slips ~ is still have several ~ let me know and I'll post some down to you).

Thanks Philip.
I didn’t realise you could overwinter slips. I certainly will give that a try.

I think they need some depth so if you’re putting them in a growbag maybe tip the bag up and plant at one end? Pargyle is the expert.
It’s not warm enough here outside and I’ve run out of south facing aspects so mine are in the poly tunnel in pots. I suspect the pots will have to be bigger next year.

Thanks for bigging me up Dani ... whilst I appreciate the accolade this is the first time I've grown them and sadly all my knowledge is internet culled, digested, composted and regurgitated.

You are right - they do need a good depths for the roots - mine are in 70 litre tubs - they were on the patio but 'er indoors kept moaning about having to clamber over them so they are now at the allotment. The root systems are massive and the tubers grow in amongst them so they need room to develop. I've got three plants in each tub but the way they are growing it might have been better with two .. time will tell.

We have a pretty mild climate down here on the Costa del Fareham and the tubs are in full sun at the allotment. I'm training the vines up bamboo cane wigwams, watering every day there isn't rain (most !) and feeding them weekly with home made comfrey tea. I don't expect to be harvesting anything much before mid September or later if the weather stays fine - perhaps even until the first frost if the vines survive. I'm thinking of surrounding them with some polythene screens to help keep the heat in. They do need a lot of heat even with slips from temperate climate Sweet potatoes.

Good luck everyone... even if I fail this year I'm having another go next year.
