March pond care in Pennsylvania

Spring rains and warming water wake the pond up. Check for winter damage and identify what is starting to grow.

• Care

  Heavy spring storms can mix a pond's oxygen layers quickly and stress fish. Penn State suggests aeration to keep the water column mixed, plus managing excess plants and nutrients.

• Care

  Look for muskrat damage: muddy water, floating vegetation, pellet-sized droppings on shoreline rocks, and burrow entrances below the waterline in banks and dams.

• Care

  Identify plants as they appear. Penn State stresses that correct identification matters most when control is needed early in the season.
