Thanks for your comment about the terracotta pot wall Umbrian. I am always looking for ways to stabilise the slope here, and the accumulation of previously used pots has provided good material for a wall. It is about 1 metre high and two long. The soil is pounded into them and between them and I walk gingerly on them to weed. The weeds are becoming less as the Sedum takes over. We had no frost much last winter so I wait to see if the pots break when it is really cold, but I am hoping that by then the whole thing will be self supporting, breaks or no breaks.
