Autumn planting
Hello. I'm planning new garden boarders, I've read that autumn planting is great for most perennials while the soil is still warm, but temperatures cooler, but does size matter? Will 9cm & 1lt potted plants establish well enough to survive winter? Or are larger versions more hardy?
How about grasses & shrubs, or are best left to later in the season or spring?
South west region, reasonably well sheltered garden.
Thank you!
