Mulching decreases competition from the grass. Grass robs water and nutrients from the tree’s root development and delays its establishment. A properly placed mulch ring helps conserve moisture and cools the soil aiding in root growth.However, mulching also has some potential drawbacks. For example, if too much mulch is applied, it can smother the grass and prevent it from getting the oxygen it needs to thrive. In addition, mulch can also provide a hiding place for lawn pests, which can lead to infestations.One notable issue is that its application can result in uneven moisture levels. If the layer is applied too thickly, it may retain excess water, while a thinner layer might allow the soil to dry out rapidly. As the mulch gradually breaks down, it can subtly alter the soil’s pH, often leaning towards increased acidity.Mulch is an excellent option for vegetable gardens and flower beds, offering moisture retention, weed suppression, and nutrient enhancement for the soil. On the other hand, bark provides durability and aesthetic appeal, making it a top pick for ornamental landscaping and walkways.
What are the disadvantages of wood chips?
The mulch also hides the soil, making it more difficult to know when to water. Also, wood chips break down and must be re-applied every year or two.

What is the lifespan of wood chips?
The longevity of mulch depends on the type you use, organic mulches like wood chips and compost need replenishing annually or semi-annually, while coarser mulches can last up to two years. Inorganic mulches such as gravel, stones, and rubber can last for many years but may require occasional maintenance.

In some cases, organic mulch can be three or even four times as expensive as its inorganic counterparts.The kind of mulch selected has a crucial role in deciding how long it can last.
