Hello, The sand in my backyard is extremely poor, apart from the fixed up bits, but I was wondering if anyone's had much luck with sand based herb spirals? It's not really something permies talk about here as the drainage is too fast and if the sand dries out it just flows away...There's not many rocks here, and even bricks are hard to find without a petrol driven horseless carriage!! It's the same with dams in sandy soils (not in my garden : ). I wonder about us poor souls with only sand and no moisture holding capacity for making dams work...what happens there ? Just curious...
