Glad to see you here, Mj. Have you peeked at the Florida Gardening forum yet? We have a thread going that is similar to the Tropical Gardens thread at DG that we so love and you will recognize at least a couple of other names. "What's in your Florida Garden". The Orchids forum here is much more active, too. Again, you will see familiar names besides mine. I'm not abandoning the other site, but I really like this one better. Aside from the cute icons, the pictures are easier to post as many as you want, and who can beat a free subscription?
On your water garden project, don't be overwhelmed by the initial complications. A water garden can be very easy care once it is set up, and gets balanced with plants, fish and water aeration. Mine goes weeks sometimes without any input from me, other than keeping the water level up. I have starts of water plants for you!
