Rock vs Mulch in Coastal South Carolina: Which Is Better for Your Yard?

In coastal South Carolina, mulch is better for plant health and soil improvement in most ornamental beds, while rock is better for drainage zones, low-maintenance borders, and areas where organic material breaks down too quickly in the heat and humidity. Most Murrells Inlet yards benefit from using both strategically. C-Scapes Mulch and More carries both, in bulk.

When does mulch win?

Mulch improves coastal sandy soil every year as it decomposes, adding humus and feeding soil organisms. Plants in mulched beds establish faster and tolerate drought better. Mulch also insulates roots through Zone 8b winters.

When does rock win?

Rock wins at foundation zones where drainage matters, slopes over 30 degrees where mulch washes out, and any area requiring a permanent no-replenishment solution.
