“A great alternative to gravel, crushed clam or oyster can be used on paths, patios, courtyards, driveways, and even bocce ball courts (the shells don’t hold water or imprints from shoes and balls),” writes Janet. “As the shells are walked on or driven over, they break into smaller pieces that disperse evenly, creating a stable surface that’s not prone to the ruts and holes you get with crushed stone toppings.”
In additional to being practical, seashell surfaces are environmentally friendly—and stylish. We’ve rounded up some of Gardenista favorites to make the case.
Parking Pads

A carpet of crushed seashells is the perfect “rug” for an outdoor dining area.
Herb Gardens

Garden Gateways

Cottage Gardens

Bocce Courts

For a DIY bocce court, first spread a three-inch layer of drainage rock. Next add a weed barrier (such as a layer of landscape cloth). Then spread a three-inch layer of crushed rock, fine gravel, or decomposed granite. You can also top dress the surface with a special bocce court blend of crushed oysters; for information, see Myco Supply.
