The hard bit Building up the main rockery wall layer by layer, I back filled with the heavy clay in the pond area. Digging small amounts of the pond as I made the rockery seemed to make the work alot easier.
I made the 3 planting areas and also dug the middle out slightly, not only to provide more earth to back fill, but also to allow compost to be added, and to create a tiered effect amongst them.
Rockery planting
I aimed the planting around aroma, appearance, and also the ability to screen the seating area from the road. I used many herbs, and plants with interesting foliage and tall flowers, as well as a tall plant in each section to prove the screen.
The bulk of the aggregates was Mellow Cotswold, creating an area that both blended with the sandstone but also stood out from it. Using moonstone (small gravel coloured white, black, and the odd one or two in red and dark blue), I edged the sandstone to make the definition of Mellow Cotswold and Sandstone clearer. Also on the right of the main planting area I added logs and branches where the ground was concrete, and "golden gravel" on the small planting area.
