It looks like I may redesign the pond this winter. I've been meaning to completely finish it - decide on a permanent design and lay the flagstone with mortar - but I've had things happen. There was a leak in the bog that was a major fix - now there is another leak, so I've quit circulating the pond through the bog. It's slowly drying out - I've watered a few of the plants - but I have to find a new home for most of them in the near future.
One of the reasons I've had problems with the bog is I didn't invest the money in this project that I should have. In hind sight, I wouldn't have spent the extra money to do it right. We didn't have the money to do it that way - we were relying on mostly donated materials and my own sweat equity. I probably bit off a little more than I could chew, and did what I could with what I had. The way I should have done it was to make the bog and the pond out of a single piece of pond liner, rather than the two that I used. I also used about the cheapest liner I could find for the bog - twice!
I'm redesigning the pond/bog to use the current pond liner for both the pond and bog. obviously the pond will be smaller with a very small area used for a bog. I will probably plant some of the other bog plants in the ground around the pond - I just have to make sure they get the extra moisture they need to thrive. Maybe I'll make a bog in the ground like I've seen lots of places around the internet. I'll put most of the carnivorous plants in that area or in pots - the one that's in a pot seems to be doing fine. I have a design in mind for all of this , but I won't know exactly what it will look like until I get in there and get digging.
