Cold-Weather Protection for Your Landscape
Tuesday, January 20, 2026 | The Greenery, Inc.
An unusually cold month in the Lowcountry has caught many landscapes off guard. While our region is known for mild winters, sudden cold snaps can stress or damage plants that aren’t built for extended freezing temperatures. The good news: with a little preparation and a few creative protection strategies, you can significantly reduce winter damage and help your landscape recover quickly when warmer weather returns.
At The Greenery, Inc., we regularly remind clients to focus on the Three P’s: Pipes, Plants, and Pets during freezing weather.
Pipes: Start with your irrigation and exterior plumbing. Disconnect garden hoses and insulate exposed pipes and outdoor faucets. Inside your home, open cabinets under sinks to allow warm air to circulate around plumbing. These simple preventive steps can help you avoid expensive freeze-related pipe damage.
Plants: Bring smaller potted plants indoors or into a garage when temperatures drop below freezing. If containers are too large or heavy to move, cover them with frost cloth or even a sheet to reduce frost exposure overnight. The goal is to trap radiant heat from the ground and reduce direct frost contact on foliage.
Pets: Bring outdoor pets inside whenever possible. If they must remain outdoors, provide an insulated shelter with dry bedding and fresh, unfrozen water. It is also a good idea to bring in food and water dishes so they don’t ice over or crack.
Beyond these essentials, there are several creative, lesser-known strategies that can make a meaningful difference during a cold snap.
Trap Ground Heat with Covers
For small shrubs or newly planted specimens, place overturned buckets or pots over them before sunset. This method captures residual soil warmth and blocks frost from settling directly on leaves. Remove covers during the day once temperatures rise above freezing to prevent overheating and allow light exposure.
Cluster Container Plants for Shared Warmth
Group potted plants tightly together and position them as close to your home as possible. Structures release stored heat overnight, creating a slightly warmer microclimate. When containers are clustered, they reduce wind exposure and collectively retain more warmth than when they are spread apart. You can further increase protection by wrapping the entire cluster loosely with frost cloth.
Insulate the Root Zone
Roots are often more vulnerable than foliage during prolonged cold. Add a thick layer of pine straw or mulch around the base of trees and shrubs, as well as planting beds. Think of mulch as a thermal blanket for the soil. Laying mulch or pine straw helps moderate temperature swings and protects root systems. In the Lowcountry, pine straw is especially effective and readily available, making it a practical winter defense layer.
Cold snaps may be temporary, but the damage they cause can linger into spring if landscapes are left unprotected. A proactive approach is to combine the Three P’s with smart heat-trapping and insulation techniques. These tips can dramatically improve plant survival and long-term landscape health.
