Falling Leaves, Feeding Koi, and Other Pond Tips

Falling Leaves Affect Pond Ecosystems:

To get some tips on how to protect our ponds, pond expert Dave Kelly at Aquascapes Inc. (St. Charles, IL) offers this advice:

“The best idea is to put up pond netting before the leaves fall,” he says. “But if you didn’t do that in time, you can use a long-handle pond net to scoop down to the bottom and pull out leaves and other debris.”

Ideally, put your net in place before leaves begin falling. Then, simply pull it out when they’ve all dropped. You can tent the net so it doesn’t sag into the pond when it gets weighted with leaves, say experts at Aquascape Inc.

Pond netting is only needed for a short time and will save you countless hours come spring. Ideally, put your net in place before leaves begin falling. Then, simply pull it out when they’ve all dropped. You can tent the net so it doesn’t sag into the pond when it gets weighted with leaves, say experts at Aquascape Inc.

Kelly also suggests trimming back and removing dead foliage from aquatic plants to help remove excessive organic material that would otherwise decompose in the water feature.

Caring for Pond Lilies in Fall:

Pond lilies are idyllic water plants. However, during early Fall, it’s a good idea to cut them back to just about the base of the plant; also trim back any marginal plants that might eventually droop over into the water.

Since some debris will make it into your pond no matter how hard you work, Aquascape recommends adding a cold water bacteria treatment, which has concentrated strains of beneficial bacteria that works well below 50 degrees (F).  Dave Kelly recommends adding it routinely to help maintain water clarity and quality.

Caring for Pond Fish in Fall

You can — and should — plump up your darlings to survive winter hibernation, by gradually increasing how much you feed the as temperatures start to drop. When pond water gets below 59 degrees, use fish food made for cold water. As the temperature continues to drop, gradually reduce the amount you feed them.

Once temperatures go below 55 degrees, says Dave Kelly, the metabolisms of pond fish slow way down. And when pond water gets down to 50 degrees, do not feed the fish any more. Their systems shut down in the colder water, and food sits inside them and rots. They get very sick and diseased from this.

Pond Fish in Fall:

There is nothing cuter than your koi coming to you for more food. However, once the water gets to 50 degrees, experts say stop feeding them entirely.

Healthy Ponds Come Spring:

Once Spring arrives, and your pond and fish are healthy and thriving, you’ll be glad you took such good care of your pond in the Fall.
