Q: Do pond weeds stop growing during the winter months?
Allen – Marcola, OR
A: Unfortunately, it’s tough to give you a definitive answer. The growth pattern of aquatic weeds and algae really depend on where a particular pond or lake is located. Weed growth in a Florida pond, for instance, will be different from weed growth in a Minnesota pond!
In general, however, you can expect to see different pond weeds pop up at different times of year based on environmental temperature, just like the weeds in your lawn. If your pond or lake freezes over, the perennial weeds will typically die back in the winter and re-emerge in the spring. Some plants, however, will continue to grow throughout the cold season, though at a much slower rate than you’d see in the warmer summer months.
Trouble surfaces when water temperatures drop to the point where your algaecides and herbicides become ineffective – but the weeds continue to grow. Algae Defense®, for example, stops working when the water is below 60° Fahrenheit, and the beneficial bacteria in PondClear™ slow down to almost a stop when temps fall below 50°F.
So what can you do?
When the chemicals and bacteria are no longer working for the winter, it’s time to turn to Pond Logic® Pond Dye. An effective year-round treatment, Pond Dye shades the water and reduces the amount of sunlight reaching the weeds and algae growing at the bottom of your lake. Less sunlight means fewer weeds, regardless of the temperature or time of year.
Pond Logic® Pond Dye comes in two formulations: Easy-to-use packets and quarts of concentrated liquid. To use the packets, which come in Nature’s Blue™ and Black DyeMond™, simply toss several in water at various locations around your pond or lake. The packet will dissolve and the dye will disperse throughout the water. To use the concentrated liquid, which comes in Nature’s Blue™, Twilight Blue™ and Black DyeMond™, pour the dye in several spots along the pond’s edge. There’s no mixing required.
If wintertime weeds are taking over your pond, consider adding Pond Dye. Not only will it shade your water and hinder weed growth, but it will also add to the aesthetics of your landscape.
