Ok, the urbanite patio is turning into a real pain in the butt, but I'm really enjoying the challenge of it. It's like playing Tetris with a jack hammer so you always win. I might be just a bit short of material to make the patio the size I want. Tempted to go bust some chunks out of my old driveway to finish it. We need a new one anyway...
While I calculate how confused the wife would be to come home to see that, here's a bog question:
Is there any use keeping 6" depth of water above gravel? Right now, the pea gravel slopes up towards the waterfall weir. Water is about 6" deep at the back of the bog, and maybe 1-2" deep at the front.
I have about a yard of pea gravel remaining that I could add if shallower water would accommodate a larger variety of plants.
