This is my first winter with a bog. It’s all new to me so I thought I’d ask the experts! We had temps drop into the low teens and light snow. The pond is fine, (has another pump),but the bog is frozen solid. I unplugged the pump to the bog, and am waiting for a thaw before I turn it back on. I hope this was right, thought I check everyone. Thanks!

Its right. It's ok for the bog to freeze as long as there is water in it. You don't want the plants to dry out and then freeze.

Thanks mrsClem, it was full of water when I unplugged it, the water has drained down into the pea gravel now and frozen. Does it hurt the pump if you don’t unplug it? With the moving water, I wasn’t sure if it would freeze solid. Do I wait for a total thaw before turning it back on? ‍

Its ok to unplug the pump as long as it is in deep enough water that it doesn't freeze. I disconnect and unplug my pump and just leave it in the pond. I don't restart my bog until e everything is thawed.

what mrsclem said; more pumps die prematurely because peeps take them out and the seals dry out until next season. Even if you do take a pump out, best to store in a bucket of water over winter.

How deep is your bog? I thought there was no way my 12-14 inch deep bog would freeze solid but now I'm concerned...

The bog is 12 to 14” deep. It is pretty frozen now. I hope it’s not unplugged more than it’s plugged in this winter. I guess that means I’m hopeful we’ll have a warm winter! The pond is not frozen at all.

That's so interesting. Around here the top of my pond has been freezing over every night, then thawing during the day. The bog is completely unfrozen, although I am still pumping water to the bog, so I guess the circulation is keeping it from freezing. My bog is also partially underground and the walls are pretty thick retaining wall blocks which probably helps with insulation.

I shut down my bog as soon as we started getting deep freezes. Filters are still running and will stay on till ponds freeze over. Pond breathers running.

I unplug our bog pump and drain the lines. Water remains in the bog and I'm sure it freezes, but plants come back in the Spring.

I turn off everything, pond and bog, usually as soon as our temperatures drop. Usually in Nov. The bog freezes (stays full of water) the pond freezes and or just slightly ices over. Depends on the winter. So far pond breathers are not on, they are in the ponds but I have not plugged in. Everyday the ponds are liquid again.

In the spring, usually late Feb the plants start growing again.

I'm in zone 6b, northeastern Pennsylvania. It can get pretty cold here for extended times.

My bog ran all last winter with no problems. It was it's first winter though.

I won't leave mine on, too much of a chance of a ice dam. With a external pump that has been running for over 20 years I do not want to take a chance of a power out and the pump taking a hit. ie freezing and cracking

We only run one pump on our pond that stays on all winter. The bog appears to be frozen but the water just keeps flowing. The few times we've had to shut down the pump, we were careful to make sure that water stayed in the bog. The plants can handle being frozen in the ice, but they don't like being exposed to the air and frozen - learned that from experience! We have a ball valve we can shut that keeps the water from back flowing from the bog back to the pump.

This freezing weather brings more bog questions! This is my first winter and I’m afraid I’m not too smart when it comes to frozen bogs. I unplugged the pump before the freeze. The water drained down into the pea gravel and froze. Now that the weather is slightly better, I’m not seeing any water in the bog. Is this normal, did the water drain back into the pond? The pond looks full, so did the the extra water just go over a low edge? When do I plug in the pump again, and put in more bog water. We have warming weather now. Forecast is for upper 40’s and low 50’s. I’ll be glad when I start feeling better about the bog. All I do is run back and forth to the pond checking for water, ice ,or miracles! I am ready for spring!

@Mackie Byars we'd need to see a picture or get a description of your whole bog and pond set up to answer any questions. Everyone's situation is completely different. Your bog COULD have drained back into the pond depending on how it's constructed. If that's the case, turning the pump back on should refill it. But it may be frozen below the surface. Where's your plumbing to the bog? Is it buried or exposed? Why did you turn it off in the first place?

The hose connected to the pump comes over the bog wall and connects to the pvc pipes under all the pea gravel. There’s about 3 feet of hose that’s exposed.

So that's a concern. If water stays in that hose when you shut down the pump, it could freeze and crack the hose. So you need to know what happens when the pump turns off.

Did you build this pond and bog?
