Wet weekend idea for sedum roof

It rains again this weekend which is ideal for helping the sedum settle in. Just like the irrigation system, when the sedum has not had any water for a while it is hours before any rain makes it’s way to the guttering. Once it does you get a slow trickly which makes it the ideal roofing cover for our low lying ground to avoid flooding. This will work particularly well with summer storms during dry periods as the sedum will soak up and store most of the water in it’s fleece carpet.
