Just as cedar is used in closets to repel moths, in the form of a mulch, it can repel outdoor insects such as ants, termites and roaches.
Cedar contains chemicals that keep it from rotting, so a cedar mulch will last a long time in the garden or flower bed and not need frequent replacing.
Cedar mulch is effective in preventing weed growth by blocking access to light and nutrients. Although it is not proven, some people also think that chemicals in the bark help suppress weed seedlings.
Because cedar bark shreds, rather than breaking up into chips, it forms a stronger mat and will not be washed or blown away by rain and wind as easily as other bark mulches.
Cedar's light reddish appearance adds color to landscaping, while helping to moderate air and soil temperatures. It also has a pleasing fragrance that other wood barks do not have.
Cedar mulch provides all the benefits of other wood chip mulches, plus a few extras of its own, making it a good choice for landscape and garden.
