The best case scenario is to have some type of shelter for your movable plants during the winter months. There are several pre-made kits available, and there are also many methods of constructing an operable greenhouse. We made a simple one by stretching plastic sheeting over a light metal frame and zip tying it in place. If you have the budget for it, many local feed stores carry the prefabricated type that sets up easily.
Greenhouse Tips:
Ventilation is important so the plants receive fresh air
Keep the climate dry by airing out on sunny days
Water plants lightly in the mornings
Other Ideas:
Dig over new borders
Repair garden structures
Prune bush roses down by half
Plant bare-root roses, trees and shrubs
Collect seeds if you are planning to start from seed
Plant evergreen shrubs is conditions are dry
Clear the remains of old crops in vegetable patches
Find the optimum level of NPK and work your soil to fit
You’ll be ready for Spring in no time!
