To keep outdoor potted plants alive in the winter, there are several steps you can take. One of the most important things is to protect the roots of the plants from freezing temperatures. This can be done by wrapping the pots in materials that will provide insulation. Burlap, bubble wrap, old blankets, or geotextile blankets are all great options for this.
When wrapping the pots, it’s not necessary to cover the entire plant. The focus should be on covering the root zone, as this is where the plant is most vulnerable to cold temperatures. By trapping heat at the root zone, you can help to keep the plant protected and alive.
I personally like to use burlap to wrap my pots. It’s a natural material that allows for some breathability while still providing insulation. I start by wrapping the pot in a layer of burlap, making sure to cover the sides and bottom of the pot. Then, I add a layer of bubble wrap on top of the burlap for extra insulation. The bubble wrap helps to trap heat and keep it close to the roots.
If I don’t have burlap or bubble wrap available, I have also used old blankets or geotextile blankets. These materials can also provide insulation and protection for the roots. The key is to make sure the pots are well-covered and that the materials are secure, so they don’t blow away in strong winds.
In addition to wrapping the pots, there are a few other things you can do to help keep outdoor potted plants alive in the winter. One is to move the pots to a sheltered location, such as against a south-facing wall or under the eaves of your house. This can provide some additional protection from cold winds and extreme temperatures.
Another option is to group the pots together. By clustering them close together, the plants can benefit from the heat they generate collectively. This can create a microclimate that is slightly warmer than the surrounding area.
You may want to consider using mulch around the base of the plants. This can help to insulate the soil and provide some additional protection for the roots. Organic mulch, such as straw or shredded leaves, is a good option as it also helps to retain moisture in the soil.
The key to keeping outdoor potted plants alive in the winter is to protect the roots from freezing temperatures. Wrapping the pots in burlap, bubble wrap, old blankets, or geotextile blankets can help to trap heat and keep it at the root zone. Additionally, moving the pots to a sheltered location, grouping them together, and using mulch can all provide additional protection. By taking these steps, you can help ensure that your potted plants survive the winter and thrive when spring arrives.
