It’s that time of year again to maintain your pond plants to get them ready for the freezing winter months. If the plants in your pond are not rated for your zone, they may not survive the winter months in your pond.

Pond plants rated for your zone will be hardier during the winter months. Hardy bog and marginal plants will need to be pruned to 2” above the soil level once the leaves begin to turn brown. Any decaying plant matter should also be removed at this time, as this can cause the water quality to become compromised during the winter months. Hardy Water Lilies and Lotus plants can be left in the bottom of the pond if the pond is at least 4’ deep or more.

Pond Plants

In smaller or shallow ponds where the water freezes solid, all plants will need to be brought indoors and stored for the winter. You are able to pack these plants in dampened peat moss and then they can be placed into the bottom of a refrigerator or root cellar for winter storage.

Non-hardy plants will need to be brought indoors for storage and some tropical plants may be able to be kept over the winter indoors as houseplants. When storing non-hardy plants, you will need to trim all of the plant to about 2” above the soil. You can then place the plant in a bucket, cover it with damp peat moss and store it in a cool dark area such as a refrigerator or root cellar for the winter. Make sure to hydrate the peat moss several times during the winter.

Tropical Water Lilies and floating plants will not survive the winter in the pond if the surface of the water freezes. These types of plants will need to be housed indoors during the winter. An aquarium with plant lighting and a heater set to about 70ºF is recommended for wintering these plants in your home. Plants should not be fertilized during winter storage, as the plants will need this time to remain dormant.
