Rubber mulch
Rubber mulch is a type of mulch used in gardens and landscaping that is made from recycled rubber, most often crumb rubber sourced from waste tires. Composition Rubber mulch generally consists of either waste tire bits or nuggets of synthetic rubber from tires that are shredded or ground up whole, after having their steel bands removed. Almost any tire can be used to make rubber mulch, including passenger vehicle tires and large truck and trailer tires. Bits or nuggets are produced from shredding and steel removal from waste tires. Rubber Mulch (Bits and Nuggets) range in size from 10 mm to 32 mm, or 3/8 inch to 1 inch. Advantages Rubber mulch provides some advantages over plant mulches. For landscaping and gardening purposes, both nuggets and buffings insulate soil from heat, allowing a 2 or 3 degrees F higher soil temperature difference over wood mulches. Rubber mulch is beneficial for soil moisture, as rubber is non-porous and does not absorb water on its way through to the soil. It also reduces fungus growth and plant growth, and becomes a weed barrier, as weed seeds dehydrate in the mulch before reaching the soil. Another advantage over plant-material mulches is its elasticity,
