Will snails survive the winter in my pond?
Cody – Falling Spring, VA
While your fish and some of your aquatic plants remain safe and sound during their winter dormancy you may wonder if your snails will be as successful. Your pond snails are amazingly resilient in cold weather and will do just fine given their habitat is suitable.
Your pond depth will play a major role in the success of all of the living creatures in your pond. Your plants, fish and snails can survive in cold water but they won’t fair too well if frozen into a solid block of ice. The ice that forms on the top of your pond varies in thickness depending on where you live but the general rule of thumb is to build your pond to be around 20”-30” in depth. This ensures there is an ample layer of water at the bottom of the pond that is left unexposed to the elements which will provide a safe haven for all of your pets and plants.
You won’t have to worry too much about your snails finding a safe place to hide over the winter as they come equipped with a strong shell which provides adequate shelter. They can hide amongst the rocks and plant remains in the pond as well during the winter but as your fish are in dormancy there is not an overwhelming need for additional habitat. As water temperatures drop and bacteria begin to dwindle a lot of pond owners tend to rely on algaecides to keep their ponds free from algae. If you are using an algaecide in your water garden review the product label thoroughly to ensure it is safe to use with your snails. When your pond comes back to life in the spring your snails will flourish amongst the new plant growth.
