Growing Hosta in Containers
I love having potted hostas in my garden, but then what should I do with them in winter? I am in zone 6 and too tight with my money to just throw them out in winter.
Some gardeners in your part of the country have told me they had good luck leaving hostas in the pots overwinter. I tend to take a more conservative approach and would rather spend a bit more energy to insure the plants survive. Here is what I do with my perennials in containers. I grow the plants in a cheap pot, usually one a shrub came in, and set it inside my fancy pot for summer. When fall arrives I sink the potted perennial in a vacant part of the garden and store my nice container in the garage. Next spring I divide and repot the perennials as needed and start the process again. If space is limited you may want to move the containers to an unheated garage. Northern gardeners may want to add a bit of insulation around the roots. Water whenever the soil is thawed and dry. I occasionally need to overwinter some containers outside and above the ground. I pack them in tight next to my garage or other protected spot. I cover with woodchips or surround with bales of straw (used as fall decoration), or some other items to help insulate the roots. I pile on the salt-free snow when present for another layer of protection and added moisture. Check these containers throughout the winter and water whenever the soil is thawed and dry.
