Rubber mulch is made from recycled, shredded tires. The resulting rubber shreds are dyed a deep burgundy, brown, green or black. Popular as cushioning under children's swing sets, rubber mulch also makes an attractive and durable weed resistant barrier around shrubs and in flower beds. The mulch helps the soil retain water and keeps flower beds warmer in winter and cooler in summer. Rubber mulch will last for years with very little maintenance.
Wash dirt from rubber mulch with a water hose. Rubber mulch is heavier than other mulches, so it won't wash away along with the dirt. If the mulch is really dirty, for instance, with spilled oil, you can wash it with a power washer and a mild soap. Rinse thoroughly.
Clean leaves, grass clippings and other debris from rubber mulch with a leaf blower. The mulch is heavy enough you won't blow it away along with the leaves.
Restore the look of faded mulch by stirring it with a leaf rake. Over time, sun can fade the mulch. Stirring brings unexposed surfaces to the top, restoring the overall color of the mulched space.
Rake the mulch periodically to maintain a uniform depth in the mulched bed.
