Pond Vegetation (Weeds)

and Algae Control


Often ponds are over-crowded with shore vegetation, algae, submersed or floating vegetation.  Vegetation can inhibit fishing, fish spawning grounds and habitat, and can contribute to the general unhealthy appearance of a pond.  Careful plant identification and a treatment plan are paramount in aquatic vegetation control.


The best way to reduce aquatic plants and algae is to reduce the nutrient load by using pond aeration or a lake bed aeration system.


A secondary approach is the use of aquatic herbicides. Hurried or unplanned use of herbicide can flip a pond by depleting the pond’s oxygen all at once.  Large amounts of dead plants create too much demand on the pond’s oxygen supply as they decompose, resulting in a fish kill.  Unsupervised herbicide use can be illegal and heavy fines may result.


What Causes Over abundance of Aquatic Vegetation and

Algae Problems: Eutrophication: Ponds that receive

nutrients faster than can be digested are considered

eutrophic waters.  Some ponds are built in a nutrient

rich area or receive great amounts of leaf litter and

fertilizer like golf course ponds and Homeowner

Association ponds.  The pond’s digestion is limited

by oxygen and microbes.  We install aeration systems

and apply bacterial amendments to help this situation.
