Does anyone know where I can buy largish quantities of slate chips. My front
garden is on a slope and we get lots of ash saplings trying to take over.
I'm thinking of planting some shrubs through anti weed matting, covering the
matting with slate chips and holding those back with junior sleepers. The
rest will be lawned so I can chop the heads off any ash saplings!

All advice / comments welcomed as I'm very much a beginner.

Thanks,

Sue
