Dinu, thank you so much for the lovely compliments! I am glad that you like what we have done to our home. We didn't have a bird bath at the time that I submitted the garden tour, but I do now! My kids got me one for Mother's Day last year.
As for watering the plants, there are no hoses in the gardens. We rely on Mother Nature mostly, but sometimes in the middle of summer, like during the drought of 2012, my husband will go around and set up a sprinkler to get the plants through the summer. Flowers can get pretty sparce in August around here and the plants can get pretty ugly and brown at times, but most of them survive.
Have a great day!
Vickie
