Sweet potato slips

I tried growing my own sweet potatoes in spring this year by suspending a potato in water but nothing happened until about a month ago! Now there ar about 4 slips and are about 6-8" high and I doubt if they will survive the winter even in the greenhouse. Any suggestions would be gratefully accepted. Thanks.

    They are not at all hardy (I seem to remember them dying back at about 5C) so all I can suggest is to keep them somewhere cool but light and inside the house.

    Give up and start again early next spring.  I left some sweet potatoes too long in the pantry and three sprouted so I planted them out under coldframes.   Took them ages to grow thru and send up strong shoots but then the heatwave arrived in mid-June and they grew like topsy.   They've had a long growing season and I dug up the first root a week or so ago.   Good haul. 

    In the UK I reckon you need to get them rooted, shooted and planted by late March and then keep them under cover till early June and keep them warm in cool spells in autumn and lift before the frosts.
