How to Prepare Your Pond Plants for Winter: A Step-by-Step Guide

If you have a pond in your backyard, you may be wondering how to keep your plants healthy during the winter months.

In parts of Australia, winter weather can see garden ponds freezing over when temperatures plumet. With the right preparation and care, you can help your pond plants survive the cold and emerge healthy and vibrant when spring arrives.

Learn how to over winter your pond plants with these helpful tips.


Clean and Trim Your Pond Plants.

Before winter sets in, it’s important to clean and trim your pond plants to ensure they are healthy and ready for the colder months. Unlike terrestrial plants where dead leaves and branches can protect and insulate the plant from frost damage, in water gardens, any dead branches or leaves will turn to sludge over winter in your pond and they should be removed. Remove any dead or dying leaves, flowers, or stems, as these can attract pests and diseases that can harm your plants.

Trim back any overgrown or tangled foliage to prevent it from becoming damaged by ice or snow. Use a clean pair of secaturs or pruning shears to make clean cuts and avoid damaging the plant.


Choose Frost Hardy Pond Plants

Some popular frost hardy pond plants include Creeping Jenny, Golden Sweet flag (Acorus gramineus)  If your pond design allows, we recommend planting marginal clumps of Golden Sweet Flag to provide some added protection from frost to your pond. These plants have adapted to survive in colder climates and will be able to withstand the winter months without much extra care.

Be sure to research the specific needs of each plant and provide any necessary winter protection, such as covering with netting or moving to a deeper part of the pond.
