I have to move some plants out of the greenhouse. No space left. I am trying to decide which of the following are the hardiest :begonias , pelargoniums, cosmos or dahlias. Any suggestions as to which I should move first? I live in the North of Scotland so frosts are still likely

to be honest I'd put them all outside during the day and then put them on the floor of the grrenhouse over night when frost is forecast. That's what I end up doing when there is no shelf space .

The Pelargoniums - but harden off first and keep the rain off them. They will tolerate down to -10 deg C, but not if they're wet and soggy at the same time. If they're Regal Pelargoniums, a little less tolerant of frost.
