Use this realistic looking alligator head to keep away predators. Floats in your pond. Solar-powered light-up eyes. No batteries required. On/Off switch included. Can be anchored with a weight to keep it in one area.
You should stop feeding your aquatic plants about a month before the first frost in your area. Even in areas that don't normally have frost, plant growth slows in the shorter, cooler days of the fall and winter months.
