How to Winterize Planters Ready For Winter

If you enjoy growing plants or flowers in planters, then you may be wondering how to winterize planters?

Planters

Are Your Planters Ready for Winter?

Many of the plants grown in planters are annuals that are discarded in the fall and replaced each spring. However, some plants such as roses can be grown outdoors throughout the winter.

Additionally, the planters themselves may be prone to cracking or other damage in colder weather.

Some species of plants that will survive winter when planted in the ground may not last as well in a container.

Ensuring that your planters will make it through the winter is possible though and this guide covers all that you need to know.

Bring your Planters Indoors

Depending on the size of the planter or your indoor space, this may not always be possible. However, if you can bring your planters indoors, this will likely be the simplest way to protect both the pots and the plants inside them.

If you are able to bring them inside, you’ll want to ensure that they’re in a good location. For example, if your planters need direct sunlight, you’ll have to find a space where they can get similar light conditions.

You’ll also have to pay more attention to watering them and general care. If you do bring them indoors, make sure that you have a schedule for care.

Cover and Group Together Porous Planters

Before caring for your planters, consider the material of the planter itself. Terra cotta pots, cast stone, glass, and ceramic planters are all problematic. Some of them are porous while all of them are prone to cracking when the temperature drops below freezing.

In order to keep them safe throughout the winter, you’ll have to elevate them off the ground. It’s also a good idea to cover them with a tarp to keep the snow from accumulating.  If you can place them along a south-facing wall with an overhang, this is ideal.

Keep in mind that even with precautions, you can still face damage to your planters so take them inside if possible.

Insulate the Sides

Although your pots may be affected by cold temperatures, you can protect them by adding an extra layer of insulation.

In order to protect them from absorbing water or rapid changes in temperature, wrap the sides with burlap and plastic wrap or bubble wrap.

Purchase Winter-Proof Planters

If you don’t have planters already but know that they’re going to be outside in the winter, you can put yourself in an easier spot by purchasing containers that can withstand the cold easier.

Sturdy plastic, fiberglass, and durable hardwood planters are the best options. You can look for ones that are labeled frost-proof as well, although you still will want to cover and insulate them.

Plant Your Planter

This may not be an option for a large planter, but consider if you have the time and space. If you have a plant that is cold-hardy and wants to protect both it and the pot, they may have the best protection by being put in the ground.

You should only do this if you have a planter that is resistant to colder weather like plastic, fiberglass, and wood.

If placing into the ground, dig a hole and spread a layer of gravel on the bottom. This will help with drainage in the spring. You can place the planter in the hole and backfill with dirt.

Your final step simply involves winterizing the plant just like any other plant in the ground.

Protect the Plants

If your planters have plants that you want to make it through the winter, you should also protect them. If you live in a windy area, you’ll want to make a burlap windbreak to provide additional protection.  This is especially important if you have trees or larger plants in the planter.

For smaller plants that you want to survive winter, group the planters together and make a cage of chicken wire to surround them. Use burlap or similar material to provide insulation. Just like you would with plants in the ground, make sure that the planters are free from weeds for the best results.
