The six simple steps to winterize a backyard pond include: one, skim and shield the pond surface with a leaf net to prevent debris buildup; two, service and store pumps and filters before freezing; three, stage aquatic plants at the proper depth for winter survival; four, pause algaecide treatments during dormancy; five, adjust fish feeding as temperatures drop and eventually stop; and six, manage ice with de-icers or aerators to maintain oxygen exchange. Following these steps protects pond life and equipment throughout winter.
