I have an old pond that leaks. I've tried fixing it, but after talking to some experts in the area I've learned that the ground underneath is all fractured limestone and there's no good way to seal it reliably. Even if it does seal, it's only a matter of time before it opens a leak - which quickly becomes an underground waterfall into the abyss. It can hold water for days or even weeks at a time, but inevitably it dries out.
So I've decided to give up on the pond and instead encourage some plant growth to turn it into a half acre wetland oasis for wildlife. Can anyone recommend some good native plants I should put in there? The water fills to about 12 feet deep when there's heavy rain, so it would need to survive full submersion for days at a time in the center. Arond the edge, obviously it would be less deep and stay submerged for less time.
I live on the edge of zone 5 very close to zone 6. We have a creek that floods pretty regularly in the spring. A section is pretty much wetland and when it floods the plants are completely submerged. I usually forage for plants in the area. Mostly skunk cabbage, stinging nettles, and cattails grow in the really wet places. Trees that grow there are larch and willows. There are also wild raspberries but I think they are higher up on the hillside.
Forget this weirdo. You guys wanna see something really neat? I just have to take off my shoe .... (hint: it's a tiny ad)
