My Dahlias have started growing from the tubers I have lifted and dried I have potted them but I have no greenhouse.
I can either leave them out and possibly fleece (although I don't have any) or put them in my spare room. Overnight lowsare minimum 7oC tonight
Cold part of the world with you I think.
Fleece will not be enough I think. Indoors overnight is best or can you cover with polythene...fleece below....? If indoors try to take outside during the day if not too cold
Thought so, got a bit over excited with myself!
Never get over excited Lizness
Yes. Give them some protection. I take it that the tubers are lightly surrounded by peat or similar. Keep the cmpost moist but not soaking. The tubers have a reserve store of water and feed. Keep an eye on the new shoots. When a shoot has made two to three pairs of leaves. You can slice these off. Some folks cut to the tuber. I prefer to cut,leaving a stump. The cuttings can then be potted up, in some cases a little hormone rooting powder or gell is useful.
It's going to freeze over the next few days and weekend so I'd bring them indoors till this cold snap has passed. They will be fine on a sunny windowsill.
