After day two, my first bog is pretty much completed. Five bales of Peat Moss and two bags of glass, its pretty much done. Hey, wait a minute, I just said two bags of glass!? What’s with that? Let me explain. I don’t know how it is in other countries, but here in Canada, Silica sand is a banned substance! You cannot purchase it any more. My substitute, ground glass. Our recycling company here in Niagara grinds glass into what looks like sand and sells it. It cheap, $5.00 bucks a 50 pound bag, its environmentally friendly, its helps out our local economy… ok its cheap! Anyway, its inert and serves the same function as the silica – to help keep the soil drained an open.
Here is my daughter filling up the bog.
After finishing the frame and digging out the inside, I covered the bottom with a thick layer of news paper. This helps protect the liner. As for the liner, pond liner is optimal, but frankly WAY TO EXPENSIVE! I’d be spending hundred of dollars for liner. What I’ve used in the past and had no issue with is vapor barrier. This is super thick stuff. I double it up and use two layers. It won’t be in contact with the sun, so it’ll be just fine.
Next five bales of peat. My daughter and I jumped around in for an hour until it was all moistened. Lastly, I mixed up a batch of 60/40 or so, glass/peat. I covered the bog with a layer about an inch or so thick. then I mixed it with the pure peat. Then I mixed up another batch of 50/50 (or so) peat /glass and covered the bog with another layer.
The finished product is mainly pure peat with a 5-6 in layer of peat/glass mix. I trimmed the liner down a bit, took one more photo and called it day! Now all I need to do is add a drain. Yep, you want a drain about 3 inches below the surface so the top of the bog doesn’t turn to soup with a good rain.
There’s lots more to be done!
