What is Rainbow Mulch made of?

Rainbow Mulch is a tire-free, non-toxic, closed-cell sponge rubber mulch. The primary ingredients are virgin (pre-consumer) rubber and plant-based materials. Our formulas are FDA and California Proposition 65 compliant and made with food-grade colorant. 

Rainbow Mulch is USA made. It is created from scratch to ensure it is the safest, most natural sponge rubber mulch available. 

Rainbow Mulch is not made of used tires. Rubber mulch that has been recycled from used tires may contain chemicals or additives that were used to create the tire, including wire or steel, polyester, nylon or rayon.
