Green Roofs

Last Night Hubby and I went to the meeting of the Master Gardeners Organization. They had a speaker on "Green Roofs". That is not the color green but roofs covered with plants. Hubby won a prize because he has seen two of them, Ford Motor Tractor Plant and the dog house at Tollgate Farm's Children's garden. I didn't expect the meeting to be that interesting because I thought you could only do green roofs on flat roofed buildings but that is not true, although the steeper the pitch the more you have to do. A green roof needs about 30 pounds per square foot more load tolerance than an ordinary roof. There were lots of examples of green roofs especially for sheds, bath houses and even carports or dumpster covers. We were each given catalogues of sedums and like plants to use. It was a really interesting meeting.
