I haven't had to water either bog garden yet. The reservoir works great for watering over time. It also fills back up when it rains.
Thanks Capensis! I haven't added U. gibba yet. I'm afraid it will get taken over with algae. I keep having to let the water garden overflow with tap water to keep the algae from getting out of control. I guess I could try a small amount.
Golden retrievers are such great dogs! Dinky is part Lab too, that's where he gets the wider head, shorter nose, and slightly shorter fur. He's such a goober, but I love him!
