Rubber mulch has the reputation for being long-lasting and durable, and has been growing in popularity in recent years. It's especially popular as a ground cover for playgrounds because of its soft and springy bounce. But it has been gaining ground in the garden as well.
Rubber mulch is a recycled product, made of old tires that have been stripped of metal parts. Landscape experts tell our consumer-services research team that the mulch does not fade as fast as traditional wood mulch and won't float or blow away like many softwood mulches do during heavy rains or high winds.
Properly installed, rubber mulch requires little maintenance compared to wood mulch and can last for 10 years or more; wood mulch is generally replaced each year. It allows water and fertilizer applications to pass through to the soil. Rubber mulch also does not attract termites or carpenter ants like wood mulch does, which will protect your flowers, plants and home from the pests.
But it's not perfect. One negative is its price; it's quite a bit more expensive than other mulch products. But because it lasts significantly longer, you may see cost-saving benefits over the long haul.
Rubber mulch cannot be tilled into the soil; therefore weeding is usually done by hand. Rubber mulch also does not provide the nutrients or organic matter to soil that wood does when it decomposes. Rubber mulch must eventually be removed.
Laying down weed fabric before adding the mulch helps with preventing weeds and also ensures that the rubber doesn't get into the ground. Experts say it's extremely hard to remove it when it does.
