Peak fall foliage is upon us here on Long Island. And while it’s a glorious sight, for those with ponds, it’s also a reminder to do a little maintenance.
Our blog a few weeks ago suggested netting your pond before the leaves fall. It’s worth doing in the next few days if you haven’t done it yet.
Once all the leaves have fallen and been captured by the net, you can simply pull it out and once again enjoy your pond unobstructed.
Note: If netting isn’t your thing, a long-handle pond net allows you to scoop down to the bottom and pull out leaves and other debris. It’s a bit more work, but effective. Also, since ponds tend to lose significant water by evaporation during the summer, clearing out debris keeps the pond from getting too shallow and requiring extra water to keep it topped off and healthy.
Aquatic Plants Maintenance
“It’s a good idea to trim back and remove any dead foliage from aquatic plants this time of year,” says Deck and Patio’s Dave Stockwell. “This helps remove excessive organic material that would otherwise decompose in the water feature. Such decaying material can cause excess gasses and undesirable algae.”
Pond lilies, for example, which are idyllic water plants, tend to need a little maintenance in 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.
Chemical Pond Treatments
Some debris will make it into your pond no matter how careful you are.
Dave Kelly of Aquasacpe Inc. recommends adding a cold water bacteria treatment, which has concentrated strains of beneficial bacteria that works well below 50 degrees (F).

Caring for Pond Fish
You can — and should — plump up your koi darlings to survive winter hibernation. As temperatures start to drop, gradually increase how much you feed them. When your pond’s water gets below 59 degrees, we recommend using fish food made for cold water.
Note: As the temperature continues to drop, gradually reduce the amount you feed them. Once water temperatures go below 55 degrees, says 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.
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.
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.
There! That’s not so bad, is it. Just remember: a little fall maintenance makes all the difference.
