Everything mulch

Benefits of mulch

Called a gardener's best friend, mulch helps soil retain moisture, stifles weeds and beautifies your garden.

Made up of organic material like shredded or chipped tree bark, a three-inch layer of mulch spread over bare soil will enhance the health of your garden in many ways, including: 

  • Retention of soil moisture
  • Moderation of soil temperature, insulating plant roots against extreme temperatures
  • Suppression of water-stealing weeds
  • Protection of drip irrigation equipment from sun damage
  • Improvement of soil texture as the mulch breaks down
  • Nourishment of beneficial soil organisms by the organic matter
  • Beautification of your garden, filling open spaces and bare ground
