Mulching can be one of the most beneficial things you can do for your soil and your plants. If you have not considered mulching your garden in the past, you may want to reconsider.
A 3-4" layer of mulch will help prevent the germination of many weed seeds, reducing the need for cultivation or the use of herbicides. Mulches also help moderate the soil temperature and retain moisture during dry weather, reducing the need for watering/irrigation. Mulches protect the soil from the impact of raindrops that can cause crusting. Crusting can prevent the germination of seedlings.
While there are many types of mulch we use in the Houston area, such as Hardwood, Cedar, Pine, Black, Deco and many others, help improve the soil by adding organic matter as they decompose. They also may encourage the growth of worms and other beneficial soil organisms that can help improve soil structure and the availability of nutrients for plants.
Mulch also can be used to enhance the look of your garden. Many bark mulches provide uniformly rich brown color that contrasts with the plants. The mulch helps keep plants clean by reducing the splash of soil onto leaves during rainstorms, and helps infiltration of the rainfall into the garden.
