Q: I am bringing my fish inside for the winter. What do I need?

Carol – Afton, MN

A: In last week’s blog, we talked about how deep your pond needs to be to overwinter your fish outdoors. As promised, this week we’ll talk about what to do if your pond is less than 18 inches deep or you think your temperatures are too cold outside for your finned friends.

Bring ‘m Inside!
Do you have a pole barn? A garage? A basement? An unused outbuilding? These places make perfect indoor places to overwinter your fish. Koi and goldfish begin their wintertime dormancy at about 45 degrees Fahrenheit, so it’s best to choose a space that hovers at about this temperature or below.

The Gear
To prepare your fishes’ winter home, you’ll need some special supplies, including:

  • Stock Tank or Holding Tank: This will be your indoor pond area. Because your fish will be dormant they won’t need a huge pond to live in, so you can get away with smaller quarters. Choose a tank that’s sized appropriately for the number and size of your fish. To make the transition easier, use a siphon to fill the holding tank with water from your pond.
  • Pond Netting: The close quarters might surprise your fish and they could try to make a jump for it, so make sure you cover the tank with The Pond Guy® Premium Pond Netting and secure it with bungee cords or other tie-downs. That will keep them safe and secure.
  • Aeration System: Just as you aerate your water garden, you’ll need to aerate your holding tank to keep the water oxygenated. An energy-efficient PondAir™ Aeration Kit will work in setups up to 2,000 gallons; a KoiAir™ Aeration System will work in larger setups with more fish.
  • Filter: If your region is warmer, you might consider adding a ClearSolution™ Filtration System (for setups less than 1,200 gallons) or AllClear™ Pressurized Filter (for larger setups) to keep your water clear and your fish healthy.

Wintertime Chores
Caring for your fish in their indoor digs is similar to what you do when they’re outside. Because the living quarters are cramped, check your water parameters with a test kit once a week or so to ensure the water quality is safe. Also, check you water levels and add water as needed, and keep an eye on the equipment to make sure it’s working properly.

Other than that, your fish should be just fine through the winter. Once spring rolls around and water temperatures warm up, they’ll be ready to stretch their fins!

My pond is 18 inches deep. Can I overwinter my fish in my water garden? | Decorative Ponds & Water Gardens Q & A

A: Great news! Unless you live in an extremely frigid climate, your pond is at the minimum depth required for overwintering fish in a pond. Though 24 inches or deeper is better, 18 inches should give your finned friends enough room to ride out the cold temperatures—as long as you keep a hole open in the ice.

Freezing winter temperatures will create a solid layer of ice on your pond’s surface. Below the ice sheet, decaying vegetation and organic matter release harmful gases, like ammonia, which can build up and kill your fish. A hole in the ice will allow for gas exchange. The oxygen will enter the pond, the gases will escape, and your fish will stay happy and healthy while they’re hibernating.

To keep that hole open, here’s what you’ll need based on your zone:

  • Occasional Below-Freezing Temps: For temperature zones that get the occasional below-freezing day or low nighttime temperatures, use an adjustable air stone aerator, like the Pond Logic® PondAir™ (up to 2,000 gallons) or Pond Logic® KoiAir™ (up to 16,000 gallons). One of these units will infuse your pond with oxygen while remaining quiet and cost-effective.
  • Long Stretches of Freezing Temps: For temperature zones that see long stretches of freezing temperatures, we recommend these options, below, based on how many gallons your pond holds. The aerator-deicer combo will give your smaller water garden the one-two punch it needs to vent harmful gases and keep your fish safe, while the more powerful KoiAir will sufficiently aerate larger ponds:

How do I “overwinter” or get my pond plants ready for the winter? – Water Garden & Features Q & A

Plants must not come into contact with ice or freezing temperatures.

Q: How do I “overwinter” or get my pond plants ready for the winter?

A: If you live in cooler climates – even those that don’t dip too far below freezing – it’s almost time to prepare your plants for winter. Each type of aquatic plant needs to be cared for in a different way, but the most important factor to remember is that the roots of your plants must not come into contact with ice or freezing temperatures. If they do, they simply won’t survive.

Keeping in mind regional variances, here’s how to keep your aquatic plants healthy, happy and ready to bloom again next spring:

    1. First, remove any dead leaves from the plants growing around your pond. Give bog plants, like irises and taro, a good inspection and clip off any unhealthy growth, spent leaves or blooms. You want your plants to go into winter as healthy as possible so they emerge strong and stout in the spring.
    2. Next, pull on your waders and tend to your hardy water lilies. Pull them out of your pond and trim them to about 3 inches above the root system. When you’re done, move the pots or baskets to 18 inches deep or lower, where they’ll be warm and safe from winter frost.
    3. If you have tropical and floating aquatic plants, like tropical lilies or lotus, it’s easiest to treat them as annuals: Remove them from your pond and mulch the soil and root balls. In most climates, they won’t survive the cold winter conditions. You can try to overwinter them in your shed or garage, but it can be difficult, as many of the tropical varieties require temperatures above 60 degrees Fahrenheit and strong light to survive.
    4. Treat floating aquatic plants, like water hyacinth and lettuce, as annuals, too. Fortunately, they’re relatively inexpensive to replace year after year.
    5. For hardy lotus, trim back the foliage after they have gone dormant and turned brown. Don’t trim them while the plant and leaves are still green, as it can cause it to be susceptible to diseases that creep in through the hollow stems. In cooler climates, move your plants to a cool, but frost-free area in your yard or the bottom of your pond, along with your water lilies.

Depending on the size of your pond and the number of plants you have, this winterizing chore shouldn’t take longer than an afternoon, but you’ll be rewarded in the spring with healthy growth that will once again beautify your outdoor living space!
