When the air turns crisp in Hunterdon County and the leaves start falling, new pond owners always ask us the same question:
“Do I really need to remove the leaves from my fish pond?”
The short answer? Yes. And we’ll tell you why, from the perspective of pond builders who’ve been elbow-deep in fall cleanups for decades.
Fall is the most important season for proactive fish pond maintenance in Hunterdon County. Why? Because what you do now sets the tone for the entire winter, and even next spring.
Why Are Leaves So Bad for Fish Ponds?
Leaves may look pretty floating on the surface, but once they start to sink, you’ve got a problem. Here’s what happens if you let them sit:
• Leaves decay, breaking down into organic sludge that clouds your water.
• As they decompose, they release tannins (which turn your water tea-colored) and ammonia (which stresses or even kills fish).
• Decaying leaves also consume oxygen, creating an unhealthy environment for koi and other pond life.
• That layer of muck becomes the perfect fuel for spring algae blooms and noxious odors.
It doesn’t take much, just a few weeks of neglect in the fall can create months of cleanup in the spring.
Best Practices for Fall Pond Maintenance in Hunterdon County
Here’s how we keep ponds in peak shape through fall:
Net Your Pond Early
If your pond is near trees (and let’s face it, in Jersey, most are), installing a pond net before peak leaf drop is a game changer. It keeps the leaves out entirely, saving you hours of work.
Skim Leaves Daily (If No Net)
If you missed the window for netting, no worries. Grab a long-handled skimmer and remove floating leaves every day. The longer they sit, the harder they are to remove.
Vacuum or Remove Debris from the Bottom
Even with skimming, some leaves will sink. That’s where a pond vacuum or a pond-safe net comes in. Scoop out bottom muck to prevent nutrient overload and winter die-off.
Trim Back Plants
Cut back aquatic plants and marginal grasses before they die back into the water. This prevents them from adding to the organic load in winter.
Switch to Cold-Weather Fish Food
Once water temperatures drop below 60°F, switch your koi to a wheat germ-based food. And once it hits 50°F, stop feeding altogether.
What Happens If You Don’t Remove the Leaves?
We’ve seen it all, fish kills from ammonia spikes, pumps clogging with sludge, and ponds that resemble swamp water come spring. The cost of skipping fall maintenance? Usually more than the cost of doing it right now.
Plus, with freezing temps coming fast in Hunterdon County, all that organic debris will settle, compact, and become a toxic soup under the ice.
