Mosquito Fern: A Small Floating Red Plant in Your Pond
Mosquito fern is not often a problem in ponds, but it can become a problem in some wind-sheltered areas. If you see a small, red, floating plant on your pond, you will know what it is. It can be controlled by contact herbicides containing Diquat or other herbicides that are absorbed from the water. Check with your biologist or a certified aquatic applicator for treatment options.
