Getting Your Pond Ready for Winter in New England
TL;DR
Getting your backyard pond or waterfall ready for a Rhode Island or Connecticut winter means:
Clear out leaves and debris early
Trim or relocate aquatic plants
Choose whether to run your water feature all winter or shut it down
Protect your fish and ecosystem with proper aeration or de‑icer
Schedule a professional inspection to catch hidden issues
By doing this now, you avoid spring headaches and keep your nature‑inspired feature performing beautifully.
At Natural Elements by Design, we view every pond as part of a living ecosystem, not just a backyard feature. As fall transitions into winter across Southern New England, your water garden deserves a thoughtful seasonal shift. With a few well-timed steps, you’ll safeguard the health of your pond—and welcome back your fish and plants with minimal effort come spring.
1. Cover Early with Pond Netting
Before the first leaves fall, drape netting over your pond to prevent seasonal debris from settling in. Once the trees are bare, simply gather the net, dispose of the leaves, and store it until next autumn. This proactive step keeps things clean, reduces sludge, and saves hours of spring cleaning.
2. Clear Debris If Netting Wasn’t Installed
No net? No problem—just grab a long-handled pond skimmer or net to remove leaves, twigs, and other organic buildup from the bottom. Leaving debris to decay under ice harms water quality and creates more work later. Clean now, relax later.
3. Don’t Forget the Skimmer Basket
Until leaf fall is complete, check and empty your skimmer basket every few days. A clean skimmer maintains healthy flow and filtration through the season.
4. Trim Dying Foliage
Cut back any decaying plants along the pond's edge or in the water. This keeps organic waste out of the ecosystem. Hardy marginal plants can stay submerged; tropicals should be removed and composted or stored if you're overwintering them indoors.
5. Winterize Waterlilies
Hardy lilies should be trimmed to about two inches above the crown and moved to the pond’s deepest area—ideally two feet or more. Tropical varieties can be composted, or you can attempt to overwinter them indoors under grow lights, though survival isn’t guaranteed.
6. Add Cold Water Beneficial Bacteria
Natural water clarity doesn’t stop with cooler weather. Add a cold-water blend of beneficial bacteria formulated to work at temps as low as 32°F. It keeps water clear, helps break down organic material, and reduces spring startup maintenance.
7. If You’re Keeping It Running Through Winter
Flowing waterfalls and streams in winter are stunning—but they require attention:
Top off the pond occasionally due to evaporation
Monitor for ice buildup or dams that could cause overflow
Ensure oxygen exchange with an aerator or submerged circulation pump
In extreme cold, a pond de-icer may help keep a hole in the ice open—but in many cases, an aerator is enough
8. If You’re Shutting the Pond Down
Many Northeast pond owners opt to power down for winter. If that’s your path, follow these steps:
Remove the pump and store it in a frost-free spot like a garage or basement
Drain plumbing lines to avoid freeze-related pipe cracks
Clean and store filter media indoors after a thorough rinse
Place a recirculating pump or aerator (like AquaForce®) on a shelf in the pond to oxygenate water and prevent full ice coverage
In particularly cold zones, add a floating pond de-icer to help keep a small open area in the ice for gas exchange
9. Make Sure Your Fish Are Healthy Before Hibernation
Healthy fish overwinter better. Feed a high-quality cold-water formula like Aquascape Cold Water Pellets as temps fall below 60°F. Stop feeding completely once water drops below 50°F—your fish will enter dormancy, and uneaten food can decay and foul the water.
