The Rights and Wrongs Of River Rock
Crushed granite, pea gravel, beach stones, and river rock: often these small rock aggregates are used to replace the entire lawn. But it can be a recipe for reflected heat in summer and a potential clog for stormwater drains — and the bare finish may alarm neighbors wary of the Arizona aesthetic.
Although we love rock as a design element, it isn’t the only substitute for grass, especially in South Texas where dense shade and handsome shrubs grow naturally. Instead of using rock everywhere, use it to provide walkways, edges, streambeds, and accents for bigger landscaping beds. Remember to put it in its place — just not every place.
