Bog over top of pondless waterfall reservoir
I have a pondless waterfall/stream that has a reservoir at the end where it stores the water for the stream as well as the pump.
I've used the water crates in the hole to take up the space and not have all rocks. The surface area is about 22 sq feet. Currently it's covered with stones and it's boring as it's just stones.
What i would like to do is remove the stones from an area and cover it with this .5" thick cocoa mat and then cover that with soil and plant a bog garden over the top of the reservoir. Not the whole thing just a portion of it. The cocoa mat would keep the soil from moving into the reservoir.
Please comment on this plan
