Really like this style: Edwarian mono-pitch lean-to greenhouse, front cold frames. Would like to create a similiar look using salvaged brick and windows!--only thing I would like to add is the other half and another set of cold frames.
Rolls of roses: Simply plunge the cuttings into the ground. Before planting cuttings, push the bottom end into a small potato, which keeps the cuttings moist as they develop roots. It sounds crazy, but the row of allotment roses is proof it works.
