Basic Pond Maintenance

Ponds require different levels of maintenance depending on what you want to do with it. First and foremost, Retired UT Extension Agent Mike Dennison says to not blow leaves and yard waste into the pond as this will reduce the oxygen level of the water affecting the algae eaten by the fish. There are several kinds of weeds in a pond. Spring is the best time to try to control them. Mike talks about the different kinds of weeds you will find and where they grow. There are herbicides available for pond weeds, but don’t treat your entire pond all at once, do it in several sections. Before you apply herbicide you need to calculate how much water is in the pond so you can apply at the correct rate. Always read and follow label directions. If you are serious about growing fish, you may need to get a soil test on the mud at the bottom of your pond and lime and/or fertilize your pond to encourage algae growth for your fish to eat. If you just want the pond for looks keep it mowed around the edge to discourage snakes and use mosquito fish and Bti (Bacillus thuringiensis israelensis) to reduce mosquito larvae populations.
