The final new garden we developed early in 2017 was our second roof garden here at Avocet. To find out about our first green roof refer to my post called “Growing up! Making a green roof.” published back in April 2013.
This, our second roof garden, was created when we got rid of one of our garden sheds and moved a smaller one into its place. (see the post entitled “Three Sheds into Two will Go”)
We constructed a strong framework around the shed in timber so that the roof garden itself was putting no extra stress on the shed roof itself. We then added a new floor to the roof garden from strong floorboards which we waterproofed with two layers of roofing felt. In order to make it ready for the planting media we added a layer of weed membrane to allow for drainage and to retain the compost. We created a drainage channel filled with gravel. The final stage of preparation was adding a layer of light weight compost which was carefully leveled.
Time to plant! It always seems strange planting when up a ladder!
The green roof is the exciting finishing point in our shed project. The first phase of planting really made us feel as if we had completed our work with the three sheds, which had now been turned into two! The plants were a selection of grasses, Incinia rubra, a selection of Carex and Stipa tenuissima but more will follow soon. Flowering plants included a selection of small Sedums, Sedum tricolor, S. telephinium ss riprechtii “Hab Gray”, S. ewersii and S. cauticola Coca Cola plus two scented Violas, V. odorata sulphurea and V. odorata Konigin Charlotte, a low growing Sedum-like plant Chiastophyllum opositifolium and a variegated Trifolium, T. pratense “Susan Smith”.
