I over ordered perennial plug plants for my brand new garden (think those bargain bundles from a big company) as assumed the attrition rate would be higher than it has been. I'm going to run out of room in the borders I've done so far and don't plan to do any more until winter now, with the ground being like concrete.
My little plugs are all now bursting out of the single cell trays that I put them in when they arrived. I plan to pass some on to the local school etc but there are some that I would like to plant out next spring in the next phase of borders.
What are my chances of potting on, successfully keeping in pots until spring, and then planting out successfully? Things like salvias, coreopsis, aquilegia. I've got a southwest facing cold frame to bunker them down in.
