Depending on the type of plants you have and the severity of your winter, there are ways to help ensure your favorite greenery sees another spring. These tips selected from gardening experts from around the web should help many of your most beloved shrubs, bushes, trees, and potted plants make it through the winter weather.
Move potted plants off concrete and onto the earth. Protecting the roots of a plant can be key to its survival. The top of a plant can often endure more trauma than the roots. Concrete can warm considerably in the sun, and then become very cold at night. This heat/cool cycle and the rapid swings in temperature it brings can damage roots.
Plant in big pots. Soil is insulation for root systems. In a 10-gallon pot you’ll have ten times the protection a 1-gallon pot provides. It can also be useful to buy a pot with a thickness greater than one inch as a means of helping further shield the roots.
During winter, water at the warmest point in the day. When temperatures climb above freezing, water your plants. Water is often used as a defense against freezing temperatures, in part because when water freezes it releases heat. Also, wet soil does a better job protecting from invasive cold than dry soil (which contains air pockets).
Position plants where temperature swings are lower. Often southern exposures will experience the greatest temperature fluctuations, so consider northern or eastern positions around the house.
Group plants defensively. Gather your plants together, placing the “weakest” of the bunch in the center and the heartiest selection on the outside, forming a border. You can also create a barrier around the group to help shield the plants from excessive wind.
Mulch for additional insulation. Mulch can help create a blanket of protection. Hay or a thick layer of leaves can also work.
Consider bringing some plants indoors. Certain potted plants might have the best defense inside. But if you do bring them indoors, bring them in before it gets too cold. The shock of moving from a chilly autumn night to a heated home can be dangerous.
With some planning and a little luck, your plants will survive the winter and thrive once spring comes around!
