Well I have my roof pretty well locked up for the winter. I unlocked it last week and here are pictures of how it looks. Lots of stuff has started growing. There are some bare spots. I hope to increase the square footage by about 50 o 75 sq. ft. this spring. I want to concentrate on sedum that stays green all winter. I'm undecided about harvesting some of what I have. I will wait until May to see how things look then. I'm also thinking of growing some other stuff in pots. I really have not been able to tell if the green roof has effected my heating bill or not. My record keeping is not up to par on that.
