koi pond maintenance

All ponds need to be thoroughly cleaned at least once a year, and the experts at Mike’s Evergreen believe the best time to do pond maintenance in the California Central Valley is winter.

Here’s why …

Fish

Fish, if you have them, are in a “resting” state similar to hibernation. Fish are cold-blooded, meaning their body temperature adjusts to the water temperature. As the water gets colder, their body temperature lowers and their metabolism slows down. They don’t need to eat much (sometimes not at all). They’re not very active, and they don’t produce as much waste.

Pump

You may be able to turn your pond pump completely off and rely on an aeration kit instead during the winter. This makes winter a prime opportunity to perform any repairs or maintenance required on the pump and filters while they’re not in use.

Plants

Many pond plants are dormant, so their growth will not be disturbed by the maintenance.

Trees and plants around the pond are in their slow-growth winter state. Leaves have fallen and can be fully cleaned out of the pond. The same is true for other plant debris.

Ready for Spring

Once the weather — and the pond water — start warming up in spring, many of the organisms in your pond ecosystem will start coming back to life. It’s best to have all your maintenance tasks completed before this awakening starts happening.

When you perform all your pond maintenance tasks in the winter, your pond is ready for spring. And your entire ecosystem will be healthier, happier, and able to give you more enjoyment for the year ahead.

Year-Round Maintenance is Still Important, Too

Keeping your pond properly maintained is essential for the health and well-being of your plants and fish.

Over time, leaves, dirt, and fish waste naturally build up in the water. As this debris breaks down, it can release harmful toxins like ammonia and nitrites, which contribute to algae growth. Algae growth is also influenced by the amount of sunlight your pond receives.

Regular pond maintenance should also include cleaning filters and skimmers, removing debris, and clearing out any dead plants to help keep your pond balanced and healthy.
