Winterizing Bog

Hi

I have a 700 gal pond with a bog on one end. The bog has a coiled flexible hose with holes in it that feeds the bog. My question is, should I turn off flow to the bog during winter?

I am in the pacific northwest a block from the ocean and winters are quite mild (zone 8). We do get an occasional thin layer of ice on the pond but can keep the waterfall ruining all year without issue. My concern with leaving the bog hose flowing is it might cool the roots of the bog plants too much. My concern with turning off the bog flow is the buildup of ammonia in the bog over the winter.

Any thoughts?

Thanks

The roots of the plants will be fine. Mine freeze solid and come back. I would leave it running esp in your climate zone.

@jbowyers I am in pretty much the same zone as you in Washington and I don't have a bog but I have plants in pots about 18" down on a ledge and they do fine w/my falls running and moving the water around.

Hello and welcome!

I live in a mild-winter climate. I let my bog run all year, and have never had an issue.

I turn mine off each winter, but I'm zone 5. The water that remains in the bog freezes solid and the hardy plants come back just fine each year.

It's not cold enough here for the roots to freeze. I am really just wondering if the roots would be warmer/better off without the flow and if ammonia buildup is really an issue once the temperature drops below 50 deg

I'm in 5B and keep my bog running all winter. I think a lot depends on your individual set up and whether ice is an issue. If you get ice build up you could conceivably have a problem with water being diverted out of the pond.

"If you get ice build up you could conceivably have a problem with water being diverted out of the pond."

You sure can! I went out a couple winters ago to find a real icy mess outside the pond and partially collapsed 3-4" ice with my pond down by over a foot. since then, once it starts really freezing up, I shut down the pump. My bog freezes solid, but the plants (all natives) come back stronger than ever in the spring.

I have a larger pond, perhaps twice your size with a 100 gallon pea gravel semi-underground bog and I run my pump all year long. I live in Richmond, VA and it does get cold enough to freeze over the top 1/2" of the pond each winter. The bog however never seems to freeze over and the plants (mostly grasses) could care less. Perhaps too much moving water. Hope this helps.
