Help! Gardening Experts - when to plant out plug plants? I recently aquired 6 each of Delphinium Pacific Giant, Lavender Hidcote, Geum Mrs Bradshaw, Digitalis Excelsior, Echinacea Primadonna and Penstemon Tubular Bells. I've potted them on and with the exception of 3 of the delphs, they're all doing quite well - especially the foxgloves which are growing out of their little pots already (only potted on 4 weeks ago).
I've been babying them up til now, (particularly the echinacea and delphiniums as my garden is overrun with snails and slugs and they adore the young leaves so they get brought in at nighttime) but my question is, what to do with them over the winter? I don't have a greenhouse, could I plant the digitalis and lavender out now and would they survive? Would I be better off planting some of them into larger pots and overwintering them in the shed? I can't keep them in the house, they're taking over!!!
Any advice gratefully received!
