Rubber Mulch vs Wood Mulch — Playgrounds & Landscapes
Compare rubber mulch and wood mulch for playgrounds, longevity, cost per cubic yard, heat retention, and when each material fits residential landscaping.
Wood mulch overview
Natural appearance, improves soil as it breaks down, standard for garden beds. Needs replacement every 1–3 years. Lower upfront cost per cubic yard in most markets.
Not ideal for fall zones under play equipment unless specified engineered wood fiber — different product than decorative bark.
Rubber mulch overview
Made from recycled tires — lasts many years, does not decompose, vivid colors available. Popular for playgrounds when installed at certified depths (often 6 inches for fall height ratings — check local code).
Higher material cost, can retain heat in full sun, and does not feed soil. Best contained with borders — pieces can scatter.
Volume planning is the same
Whether rubber or wood, order by cubic yards from area × depth. Playground specs may require deeper fill than garden beds — recalculate volume before ordering.
Frequently asked questions
Is rubber mulch safe for gardens?
Most food-garden guides recommend wood-based mulch. Rubber is marketed for playgrounds and paths, not edible beds.
Does rubber mulch need more depth?
Playground installations often need 6+ inches for impact attenuation. Decorative use may match wood depths — follow manufacturer specs.
Which lasts longer?
Rubber lasts many years. Wood replenishes annually as it decomposes — a feature for soil health in planting beds.
