Sorry, my very unclear post.  I have bought a very healthy sweet potato plant from b and q and  I was thinking of taking cuttings from it.  As you tell me I only need one for a grow bag, I think I will  stick with the one this year and expand next year if I am successful.

I can recommend b and q sweet potato plants to anybody who hasn't managed to sprout their own.  Mine is (as I said) quite big and very healthy (though I know plant quality varies at different b and qs).  They are £2.98, which might be a problem if you want more than a couple.

one sweet potato to try,have it suspended on the jar of water on a warm windowsill......all I have is a good root system,not one sprout on top....

The root system means the sprouts will soon come. Be patient.

I remember an old post was saying you need to put the whole sweet potato in water for a day before suspending it on a jar, this is because some sweet potato in shop was treated with 'anti-sprout chemicals' before they were put on sale.

maybe you can drown it for a day then change water and see what happens.

It worked for me but that doesn't mean it would work for everyone (or even that you have to do it.) 

If you've got roots I'm sure your tuber will deliver the shoots sooner rather than later.

Don't worry!  I put mine in pots on the windowsill weeks and weeks ago then I was literally just washing up and glanced at them and two of them have some sprouts!!! woohoo

Mine is just developing a sprout, but I have a feeling it is too late, they won't have a long enough season to develop into tubers.  I also have a shop bought plant that is at least 6 weeks in advance of my sprout, so I will try them both.

I heaved a half barrel into the greenhouse and filled it with a 60L 'grow veg' compost and a bit of soil, and mixed in some BFB.

How many rooted slips can I plant in it? ............(I have 3, thanks Jay )

[Trillium]

2 would be enough but as you have 3, you could always try all 3.

I bought five plants from ebay and was considering planting two in a greenhouse and three through black plastic under a poly tunnel. What do you good people think?

[Trillium]

The protection is a very good idea in the UK. Sweet potatoes really do need lots of warmth to grow well, and over 4 months, so greenhouse and polytunnel should do well for you.

[Thephoenix572]

Thanks for your support. I'd post pics of the plants from my ipod but can't work out how to do it

These are my sweet potato plants which I'm going to plant next week

[Thephoenix572]

I planted three sweet potato plants through black plastic and under a poly tunnel hoping that they flourish

[dig4victory]

My sweet potties are all producing really strong shoots no and strong roots (they are still in the water).  As it's half term next week, I will get on and pot them up.

What I am going to do is cut a little chunk out of the pottie around the base of the sprout and plant that up, I just don't like the idea of twisting off and pulling out the sprout as done on one youtube vid I watched...

I maybe late but am going to give it a go anyway and it'll be good practice for next year if it's a no-go this time.
