Bare root roses
I'm expecting 7 bare root roses tomorrow (Friday), which I'm planning to plant in the ground at the weekend. I've just checked the weather forecast and the night temperature in my area on Saturday is expected to be below freezing. I know I should not plant them if the ground is frozen, but in this case the ground will not be frozen when planting but frozen later at night.
Please can someone advise me if I should go ahead and plant them in the ground or just keep them in a pot with dry compost until spring (as I've read from someone else's post the other day)?
Many thanks in advance!
