Enjoy water features all year by winterizing

For many people with backyard ponds, fountains and other water features, the arrival of cold weather means draining the pipes and pulling the plug, but water gardens can be attractive winter gardens, too, with the right preparation and landscaping.

Turning off a garden’s water fixtures may not be necessary, depending on where you live, said Keith Folsom, president of Springdale Water Gardens in Greenville, Va.

“Their wintertime effect is always different and attractive with the use of landscape lighting and the right plants.”

Ensure that water lines and fixtures are drained if you do decide to turn them off so they won’t expand with freezing and break, Folsom said. “Running water, on the other hand, prevents icing. That’s one of the reasons I tell people to keep them running.”

Add evergreens

Landscaping around water features can mean simply adding a few evergreens for contrast against the drab browns of winter or stringing some lights around them.

“People who live in the South will most likely keep their ponds going and use cold- and frost-tolerant landscaping for visual interest,” said Tavia Tawney, technical services manager for Aquascape Inc. in Chicago.

Winterizing strategies

Here’s advice on preparing your pond for the winter:

Remove debris before it can decompose. That prevents organic rot, loss of oxygen and an accumulation of toxic gases. “But the bigger problem comes if you stir it up,” Folsom said. “That can turn up bacteria that will be harmful to fish in winter.”

Use netting. Cover the water with a screen, sweep the surface with a long-handled net or install skimmers like those used to vacuum swimming pools.

Prune. Pinch off aquatic plants as they die back. Reposition your hardy potted water lilies into deeper water. “Tropical plants will die after a hard frost and should be removed then, or you can bring the tropicals inside the house for winter,” Tawney said.

Stop feeding the fish. “It is very important to stop feeding the fish once water temperatures reach 50 F, as they go into a deep slumber and do not digest the food they may eat,” Tawney said.

Use a bubbler or tank heater if you have fish. “We use an aerator bubbler to add oxygen to the pond if the waterfalls are turned off,” Tawney said.

It’s best to maintain water gardens throughout the year rather than scramble to get things done before winter sets in, she said.

“It is not advisable to do any major cleaning once the fish are hibernating because that is very stressful for them,” she said.
