Rubber mulch is the best thing since sliced bread! It lasts darn near forever. Doesn't break down or disintegrate. Doesn't lose its color. Doesn't poke you or stain your clothes. Its a little heavier, so it doesn't wash away as easily in the rain, wind or when leafblowing. It is more expensive than wood mulch, but you don't have to reapply on a yearly or bi yearly basis. It has much longer life.
