What stones should I use for my backyard sanctuary?

You can cover it with pebble stones or make stepping stones out of concrete

Stone/concrete slabs - Shingle over a membrane - Shredded Rubber -Bark.

Your local stoneyard will have vast supply of stone in different colors textures and shapes. I suggest having a visit there and see what you like. Often they have terrific catalogs for ideas on how to install stone and pavers products with different design options.

Also I’m not sure of your location but Ive found that sedum is a great plant that adapts to areas where nothing will grow. If adaptable to your planting zone - you might want to consider adding some sedum to your backyard area

Here's an idea of an ugly space transformation into a garden path with the use of stones. Good luck! Hugs, Holly

I have a similar situation, but rather than all stone I have "encouraged" moss to grow.
