I think the "10C minimum" rule applies here, and I suspect ideally a good deal warmer than that - my sweet potato triffid will continue to live on the kitchen windowsill (threatening to strangle me every time I do the washing up!) until at least this current cold, wet spell is over.
Sow your seeds, plant your plants. What's the difference? A couple of weeks or more when answering possible queries!

One of the best things about being an orang-utan is the fact that you don't lose your good looks as you get older

Thanks JayG!  I currently have some 1st earlies growing in the space in the tunnel that I want to put sweet potato plants in when they're harvested so hope they'll be out in time.  I planted those about three weeks ago. :-)

If you remember the key timing: 4 months for growth in the hottest weather, then you can calculate when to plant them.

For others wondering when, a good idea is to warm the intended planting area by placing black plastic over the area for a few days to heat up the soil. Plant the sweet potatoes, and immediately cloche the plant until it either outgrows the cloche or the weather is hot enough to remove the cloche. Mind, the planting still needs to be done in late May rather than now.

For those with good sprouts, now is the time to carefully twist off the sprout from the main potato (don't need to remove any potato with it) and either plant the sprout in some damp compost in a pot for each, or put the sprouts in a clean jar of water for a week or two and then pot in compost.

I know it seems very odd, but this is how it's done.

Thanks Trillium! :-)
I plan on buying the plants (not slips) in from a reputable source (yet to find) and plant immediately as soon as the plants arrive.  I will take on board the advice on putting a cloch over the plants to maintain heat, and let you know how I get on (with pictures hopefully)! :-)

All the best.

Finally have some sprouts going!

It took a long old time, but I think this is because I place the tuber in the coldest room in the house - the utility room.

Next year I'll put it in an upstairs bedroom.

It's really hard to say why one potato rotted while the other didn't. My guess would be how it was grown and how much fertilizer it had versus manure. Fertilizers tend to make softer growth in my opinion and the large one might have had that problem.

If you have no sprouts yet on the other one, then sadly you won't get a crop this year. However, keep water on it and it will keep growing into next year and you'll be ready then.

I have just taken delivery of some plug plants which have now been potted and are bathing in the warmth of my greenhouse ready for when the time is right for planting out.  I have read all the comments and advice with interest as this is the first time I've tried growing sweet potatoes.  Fingers crossed and wish me luck!!!!

My Ebay potato plants have arrived today also and are now in pots in the bedroom window ready for the end of the month to be planted in the greenhouse
All the way from my allotment in beautiful Derbyshire. I'm in year 3 of my allotment and wish I'd caught the bug years ago, things growing from strength to strength

brian - you're best to try to grow those shoots this year as they will be hard to overwinter in UK weather, even indoors. The main potato tuber, in good shape, will easily overwinter indoors but not pulled shoots.

Good work, Nige. When you plant them out, cover them with a bottle cloche or something to retain as much heat as possible.
