Non-Organic Mulch Alternatives for Foundation Planting Beds

Homeowner hears mulch attracts termites/toxins. Wants alternatives for front entry.

Inert Mulches

• River rock / pea gravel – natural, durable.
• Crushed oyster shells / coral – regional, light color.
• Shredded rubber tires – colored, long-lasting.
• Tumbled glass – decorative, "dry creek" look.
• Human hair – studied in China, excellent mulch (but not commercial).

Termite Prevention

• Keep 6 in clearance between any mulch/soil and wood sill.
• Termites build mud tubes over barriers—inspect annually.

Pine Straw pH

Acidifies soil → good for azaleas, rhododendrons, hydrangeas.
