Skip the Rubber Mulch
Gardeners are always searching for better looking, longer lasting and less expensive mulches. Rubber mulch has been advertised as an attractive and permanent alternative. Think twice before using rubber mulch in the landscape.
Recycling tires is important, but the lack of performance in the garden and harmful qualities make rubber mulch undesirable in the garden and landscape.
Research found woodchips were more effective at suppressing weeds rather than rubber mulch. They also found it was one of the more flammable mulch materials and hard to extinguish once it caught fire.
Leachates from rubber also contain metal and organic materials that are known to be harmful to human health and the environment. They can cause skin and eye irritation, major organ damage and more.
So stick with the organic materials that not only suppress weeds, but improve the soil as they decompose.
A bit more information: Save money and be kind to the environment by using fallen leaves as mulch in the garden. Shred the leaves with your mower and spread over the soil surface. They are great in annual gardens since they can be dug into the soil at the end of the season.
