Our SW+A Green Roof modules will be two years old this summer. They are not looking too great at the moment because of three possibilities: the sedums have declined over time, the soil has lost its nutrients or they have experienced too much rainfall this winter. We are positive our modules will bounce back this summer and we plan to give our test samples some extra attention in the next few months.
Green Roofs are almost nonexistent in our area and it will be interesting to see the first large commercial installation. Find more information about Great Green Roof here.
