Mulch is a layer of different materials that serve to improve tree growth, soil fertilization by preventing water evaporation from the soil and reducing the growth of weed species. The material used in the mulching can be organic or inorganic in nature. Despite the fact that it acts as a protective layer for the soil, it also enhances the appeal of the trees. Here are some reasons why you should mulch around your trees.

Mulch serves as a covering of different materials that can be organic and inorganic to improve tree growth, reduce evaporation of moisture from the soil, and to protect trees from weed species. Mulch acts as a protective and decorative thing for trees. Organic Mulches are usually made up of compost, bark, wood fiber, leaves, peat moss, and pine needles, these organic mulches are decomposing and need to be replenished after decomposing. Whereas, Rubber Chips, Stones, and brick chips are used as Inorganic Mulch and usually for decoration purposes. Organic mulches improve soil structure and fertility but inorganic mulches do not impact soil structure so they must be removed after some time.

Benefits of Mulching

There are several advantages of applying mulch:

  1. It maintains the moisture of the soil.
  2. Mulching helps a tree by keeping roots at a suitable temperature.
  3. It controls and eliminates the growth of weed species.
  4. It improves soil structure and drainage.
  5. It also reduces the chance of mechanical injury to a plant.

Some Tips for Proper Mulch

Mulch should be applied in a round form around a tree, it should be far from the tree trunk by allowing air to flow freely. Mulch should not exceed more than 6 inches. Farther applied Mulch from tree trunk helps in providing nutrients to roots easily because roots will not compete with lawn. Mulched soil mush better than bare soil, because it varies the temperature of soil according to the weather, they are warm in winter and cooler in summer. This protects roots from freezing and dying in extreme weather. It also maintains a good moisture level in soil in sunny weather a mulch acts as a protective layer that blocks the direct impact of sunlight on soil that evaporates water from it. Soil can be dispersed by rain and the direct impact of water on it, mulch protects soil from getting breaking it acts as a sponge and slow down the water.

Disadvantages of Mulch

There are several disadvantages that can be caused by improper use of mulch or mulching material:

  1. Some inorganic materials like plastic that is used for mulching can cause a barrier for water and oxygen to enter the soil.
  2. Also, dark color mulches absorb heat in the day and then release it at night, this can cause damage to root tissues.
  3. Some organic types like straw, hay, and leaf litter can cause shelter for weed seeds and they should be composted before applying.
  4. Mulch that is applied too much close to a trunk of the tree can cause root collar tissue to rot and it can become an epicenter for most of the insects.


You can choose the mulch of your choice according to cost, purpose, and preferences. Before choosing any kind of mulch material make sure you know how you will utilize it. Organic mulches provide good and natural aspects to soil and enhance its nutritive properties. Whereas Inorganic mulches are mostly used for decorative and aesthetic purposes of the lawn. Both these kinds of mulches are good for the soil in their certain way, and they are supposed to preserve soil from weedy substances and maintain a good moisture level for growing roots.
