Rose softwood cuttings

Hi All,

I'm after some advise from anyone that knows a bit about cutting from roses. At the moment I am using a small zip lock bag over the top of the pot to help keep moisture as has been advised on various sites.

I'm not sure at what point I can remove the bag without killing off the cutting? At present they have been in for about 3 weeks and there is new leaf growth on all of them. I've had a look at one of them for root growth and there seems to be a tiny amount starting on the stem but nothing really resembling a root at the moment.

I took some softwood cuttings from a rambler rose and just dibbed them into some hormone rooting powder, then into a pot of compost. I don't think I put a bag on them, but they were in my greenhouse for a bit then went outside, where I promptly forgot about them! I got two good plants.
