Pond Boss Forums MANAGING AN EXISTING POND Fertilization fertilizing and watermeal

Meadowlark learned the hard way. Fertilization should be done only in ponds where rooted vegetation and filamentous algae are not present or at minimum amounts. Theory is that fertilization should start before weeds and algae start to grow. Putting fertilizer in a pond with filamentous algae and or rooted weeds is like puting more wood on a fire. Existing plants are stimulated by additional nutrinets and usually outcompete the phytoplankton.
