Winter Pond Care - Plants and Fish
Print This Article
Winter pond care requires some special care, not much, but just a few things to watch. If you have not done all the nasty fall care, you must do it now. Trying to remove debris through the ice is impossible.
Your pond changes in the winter. The fish are in torpor, a word for fish hibernation, as soon as the temperature drops to 43 degrees F. Their metabolisms have slowed and they are hanging out where the water is warmest - at the bottom of the pond. They hang out in a tight group to stay warm. They are not eating because they cannot digest food at these temperatures. If you feed them and they do eat the food, the partially digested food will kill them. They can survive if the pond freezes over, but only if you keep a hole open in the ice so gasses can be exchanged. If they have no oxygen, they will die.
If your pond freezes solid, do not leave any fish or living creatures in the pond. They will not survive.
Any plant material or fish waste left in the pond will decompose and cause a build up of toxic gases and your fish will die, as will any frogs, turtles or toads. The aeronomas bacteria produced continues to grow and your pond inhabitants will die. And it will be your fault. And this decomposition quickens in the spring faster than your fish come out of torpor and can become even more dangerous.
Turtle, frog and toad care
Make sure the frogs, turtles and toads have mud to burrow into. Inside the house is better for them, but most of us don't have a spare room to house our turtle, frog and toad population. If you must leave them out and can't get them out of the pond, try this trick. Find a plastic dishpan or plastic box and fill them with sand, dirt and kitty litter. Put the box in the bottom of the pond. They will dig in and hibernate there. When the weather warms in the spring, you can remove the temporary rooms in their fine hotel and pack them away until next winter.
Cut all bog plants back. Or remove them from the pond. You did this when you prepped for fall, right? The plants will die all the way back even if they are hardy plants. They will return in the spring bigger and better. If you have tropical bog plants, they need to come in the house with the water lilies. It's getting crowded in the house.
Water lily care
If you have hardy water lilies, drop them to the very bottom of the pond. If your pond freezes solid they have to come in the house too. If you have a greenhouse or something you can turn into a green house, it's better because the water in that pot can get pretty rank before spring arrives and your lilies can go back outdoors.
If you live in a part of the country where the pond would never freeze solid, you are fine leaving them in the deepest part of the pond. Water lilies thrive at 10,000 feet in Rocky Mountain National Park lakes.
If you have tropical water lilies, you must bring them inside where temps do not drop below 50 degrees. If you have a greenhouse, all the better because your house is now full of plants sitting in water. If you live in the south, as I do, you can put your tropical lilies in the deepest part of the pond and they have at least a 50-50 chance of survival
You may also remove the lilies from their pot, rinse them well and store the tubers in a sack of damp sand, again do not put them where temperatures drop below 50 degrees F. Remove them in the spring and repot. Be sure the tubers are firm. If they are mushy, throw them away. You will have plenty, don't worry. In the spring you will be able to pot up plenty of lilies to give to friends.
