I have approx 40 geranium cuttings in individual pots at the back of my "under-stair cupboard". They are in a warm dark place. As the winter subsides, when should I remove them and put them all in my greenhouse?
Thank you

If your greenhouse is unheated, it could be a bit of a problem at night for the first 10 days or so. If you have a bit of heat in there, you can move them now, if not, then you could put them in there during the day, but you'd have to bring them inside overnight till they're hardened off, over a period of about 8/10 days. They will withstand up to ten degrees of frost, as long as they're not damp or wet, but yours are currently tender little things, having been cossetted inside a warm house over winter.
