Gardening Methods

My gardening book lists plants to grow on scree and dry walls. Does this mean no soil is required?

I have recently had my front garden landscaped, mostly shingle and groups of rocks. Very low maintenance but rather bare (my daughter calls it “Stonehenge”). I am considering ornamental grasses, but would like some colour and cover. I must admit I am not an enthusiast!

You would be best to add some soil into the cracks before adding the plants. On old, established walls, the mortar and rock have deteriorated a little to make their own soil…..the seeds or spores just happen to land on that and can grow.

Speed things up a bit and just stuff some soil into the crevices.
