i have put a sweet potato that  i bought from a supermarket in a jam jar supported by three cocktail sticks and suspended in water, this will make the slips that i will grow in the allotment later in the spring.  they will need to be on the plot for about 6 months to get anything worth eating!  Check out the other threads for ideas ref sweet potatoes.

So do the slips come out of the potato?

I have just asked the same question and some kind folk has posted some photos on Edible Plants

To grow a Sweet Potato Vine

Sweet potatoes in the U.K. are grown mostly in the South. They are planted in the spring by "slips." These are the small rooted pieces of the vine that grow from the "eyes" or buds of the potato.

The sweet potato produces vine-like stems that resemble the philodendron plant. Place the sweet potato in a container of water. Keep the top 1/3 of the potato exposed by placing toothpicks into the sides. The pointed end should be down in the water. In a few weeks a vine with several stems will begin to sprout. The stems are weak; so be careful not to break them.

Fertilize about once a month.

When the shoots are 10-15cm long, gently twist them from the potato. Place the shoots in water so that their bottom halves are immersed. The slips (shoots) are ready to plant when roots appear, usually in just a few days. Don't allow the roots to get longer than 2.5-3cm before planting. Your sweet potato vines can be planted outside in two weeks after last frost to produce sweet potatoes that can be dug and eaten in the autumn.

How long before roots and slips are produced = once suspended in water?

Mike,
Very informative. Many thanks - now sorely tempted to give it a try.

Thanks SO much for that! All drawn and jotted down in my new allotment notebook. :)

When you say fertilize for 1 month, what exactly do you mean for fertilizing? Or just leaving in the jar...

Fertilize Once a month- teaspoon of tomato feed.

Anything from 1 to 3 months.
