Before applying mulch, add some fertilizer that has a lot of nitrogen in it to the soil, as mulch tends to take in a lot of nitrogen, which can harm plants. If you are using fine mulch, spread it on the soil to make a layer about 2 to 3 inches thick. If you are applying coarse mulch, make a layer that is 4 to 5 inches thick.
Try not to mulch too closely to trunks of trees, as mulch may attract pests. Other than that, mulch is beneficial for plants, and it keeps weeds from growing in your garden too. There is not a specific time to apply mulch to your plants, but if you plan on applying mulch in late fall or during winter, and you live in a cold area, allow the ground to freeze before applying mulch.
There are two main types of mulch, including organic and inorganic mulch. Organic mulch is the best option for people who do a lot of garden work that requires digging the soil. This kind of mulch includes wood, bark, compost, grass clippings and leaves. This type of mulch doesn't cause harm to the soil if its mixed with it, and it decomposes during a few years.
An example of inorganic mulch is stone. Gardeners need to place this type of material on the soil permanently and leave it alone, which means not being able to dig the soil or rearrange the plants.
