Winter Plant Preparation
Before you prepare your pond plants for winter, it’s a good idea to clear as many dead leaves and debris as possible out of the pond and cut back any wilted plants around the edge of the pond.
Removing decaying leaves and other debris that has fallen into the pond will help to reduce toxic gases like hydrogen sulfide building up in the pond over winter. These gases are toxic to fish.
Hardy Pond Plants
Most hardy aquatic plants go dormant over the winter months and the foliage dies back, so you can stop fertilizing the plants as the weather starts to cool down.
Hardy water lilies are one of the most popular pond plants and they don’t need much care over winter.
Just cut back any leaves that have turned yellow and submerge the pots in a deep section of the pond where the water is warmer over winter.
Lotus can be treated in the same manner and they’ll survive the winter as long as the tubers don’t freeze.
Non-Hardy Pond Plants
Non-hardy pond plants can be grown as annuals in areas with cold winter temperatures.
These plants are invasive in many areas so it’s important to ensure that they’re disposed of properly so that they don’t make their way into public waterways. 
Tropical plants like canna lilies don’t tolerate cold winter temperatures and need to be moved inside before the temperatures cool down.
Place them on a saucer filled with water near a bright window to keep them healthy and happy over winter.
Submerged plants like hornwort and eelgrass will survive the winter if they’re fully underwater.
Any parts of the plant that are close to the surface of the pond may freeze, so you can sink them deeper into the pond or trim the tops of the plants.
You can also overwinter submerged plants indoors in an aquarium with good lighting.
With some careful preparation you can ensure that your pond plants survive the cold winter months.
If you have a small garden pond, it should only take an hour or two to prepare your pond plants for winter and you can look forward to healthy, thriving aquatic plants once springtime arrives.
