Sourcing Oyster Shells for Landscaping in Southern California

West Coast Supply Is Limited

Oyster shells are abundant on the East Coast (historically used as concrete aggregate in Maryland) but not commercially produced on the West Coast due to lower natural reproduction rates.

Alternatives

• Crushed seashells from local seafood processors (may require rinsing).
• White marble chips or limestone gravel for similar aesthetic.
• Recycled glass aggregate (tumbled).

Check with local landscape supply yards; some may import bagged East Coast shells at a premium.
