Importance of Mulch

Mulch Mulch Mulch! I cannot stress enough the importance of using good aerobic organic material for mulching shrub, tree, perennial, & flower beds. It is the best multi-use tool in the landscaping arsenal.

“During the summer, when 50 to 80 percent of our water consumption is used outside — we may waste as much as half of the water we use! – Texas Water Development Board”

Bare soil is huge problem that does so much harm to our soils and plants. Visiting the piney woods of North Houston/Spring/Conroe or the prairies of South Houston, you will see what we call “mulch” happening all around you. Nature uses dead material to protect the living soils that support plants.


  • Prevents the crusting of bare soil“When water droplets land on bare soil, the impact causes soil particles to fly in all directions, resulting in soil crusting and slow water infiltration.”(1)
  • Provides habitats for the microbes
  • Reduces erosion
  • Maintains temperature during our scorching Summers & any cold Winters we may have.“A 3” layer of organic mulch can lower soil temperature by about 25-30° F, which reduces plant stress and water requirements. Bare soil can easily reach 100-135°F, which speeds evaporation and dries out the soil, which stresses the plant, resulting in wilting, more insect and disease problems, and in most plants, eventual death”(2)
  • Feeds the soil microbes
  • Reduces Evaporation – “A good layer of mulch can save up to 1500 gallons of water a month.”(3)
  • Suppresses weed growth

NOT all mulch is equal. Make sure you are applying the best for your scenario. Take a look at the types of mulch available for the Greater Houston Area.
