What is a good base for landscaping stones?

Emile Okafor: Sand would work fine but no matter what you use you need to put landscape cloth down first. It keeps weeds from growing and still lets water through. It will also keep the sand from mixing with the dirt underneath. You might put a second layer between the sand and rocks to keep them from sinking into the sand. Good luck.

Pamela Meno: The stones are 2 1/2 inches thick and 11 1/2 inch square.

Ervin Overbee: 3/4 inch or smaller stone
