Pros And Cons of Wood and Rubber Mulch

Infestation Possibilities

Rubber mulch is often ideal when trying to avoid most pests, such as termites. Termites can often become an issue in the garden when using wood mulch because they use wood for food and travel means. A lot of bugs are attracted to moist or rotting wood. So if you want to avoid pests and insects, go with rubber.

Here is a completely different kind of pest, fungus. The answer is the same though. Rubber mulch decreases mold and weeds in the garden because it often dries out weed seeds and spores before they can break soil. Wood mulch often attracts and supports the growth of fungus. It has also been known to get “artillery” fungus that can spread to nearby objects, such as homes, and remain forever once dried.

Individual Benefits and Downfalls

Wood mulch is often used because it can provide the soil with some benefits that will last a long time when the mulch breaks down. But you must also think of the high carbon levels. The carbon in the wood will need nitrogen, an important factor to a garden, to break down. It may take this nitrogen from its surroundings, which means taking it from the garden. But, when considering the cost of rubber versus the cost of wood, wood is a much cheaper wood. It also breaks down faster, meaning that often replenishment is necessary.

Rubber mulch makes for great insulation and drainage, but while regulating heat and moisture. It is more expensive than wood mulch, but it lasts longer so it does not need to be refreshed as much as wood mulch does.
