With winter approaching I’ve taken steps to eventually move some plants into the greenhouse but others I’ll probably leave outside and cover with some frost fleece when the time comes. In general, keeping outdoor container plants alive during the winter months isn’t difficult if you keep an eye on shifting temperatures and take quick action when necessary.It’s important to remember that container plants die because the roots are susceptible. Instead of being insulated underground, container plant roots are left, virtually out in the cold above ground.
Taking note of the following tips should help:
Dry soil is deadly during a frost. Make sure your container plants are sufficiently hydrated before freezing temperatures hit. Check the soil periodically, especially if your containers are wintering beneath an overhang.An ideal place to overwinter container plants is in a greenhouse or coldframe. Otherwise, move susceptible plants into a shed or garage or cozy them up along the south side of your house when freezing temperatures threaten.
Protect species at special risk of frost damage by wrapping containers with insulated thermal blankets, bubble wrap,frost fleece or bales of hay.One of the easiest and most effective ways to protect sensitive plants is by mulching. Mulching with an organic material will also help enhance the soil as the mulch decomposes and releases nutrients to the earth. In autumn, pull back old mulches from the base of plants and spread a new 3-inch layer around them out to the drip line. Leave a 1/2-inch space around the plant’s stem to allow air circulation and prevent rot.
Surround tropical plants with a cage of chicken wire and stuff with chopped leaves or straw.This is the time when everything is returned to the soil: leaves are falling, stems collapsing, insects dying. The earth is receptive now, drawing in energy while all above is going dormant.
Clearly it is important to remove tender plants, such as dahlias and even woody shrubs such as lemon verbena, that can be lifted, brought in and potted up for a warm winter indoors. And, of course, it is valuable to remove all unwanted matter to the compost heap.Yet, in an organic garden, the natural decaying impulse of the season should be allowed to unfold because that is nature in action.
