I have been planning to build a bog ever since I moved back home two years ago. I've finally did it.
I'm planning to fill it with plants that I won in the NASC auction.
I used the blocks that used to build small walls. I built it up two blocks high, then laid a sheet of plastic in it. I used the third row of blocks to hold the plastic .
Here's a few pics from the construction.
I used the plastic peat bags as filler for the bog. Instead of throwing them away to take up space in a landfill, I just through them in the bottom of the bog and covered them with the peat that came in them. I used 8 bails of peat.
The last bog I made was an in ground bog. Even with drain holes, I had problems with flooding, and that was without the rains from a hurricane. With the threat of 20+ inches of rain in one day if we have a hurricane, I had to come up with a way to drain the bog. I also had to think about long droughts that we have, like the one we are in right now.
Here's the system I came up with.
On top of the sheet of plastic, I took a large bowl, turned it on it's side.
I filled it full of rocks. I took a 1 1/2 " hose, tapeed a screen to one end to prevent clogging. I stuck the screened end into the rocks and ran the other end under the blocks.
I capped the end. If we are expecting a large rain, I'll just remove the cap. If it works the way I hope, the water will drain to the lowest level (the bowel with the rocks.) The water will drain through the rocks into the tube and with the cap removed, it'll drain outside of the bog. (I hope)
Here are the plants I have right now to go into the bog.
I've only gotten a few of my auction plants yet.
Here the plants after being planted.
