Why mulch your landscape beds?

With the drought that the Dallas area has seen this year we recommend to our clients they mulch their landscape beds.  Mulch is a material that is used to protect the soil and to inhibit weed growth by covering the ground.  They can benefit the landscape beds by preventing erosion, suppressing weeds, retaining soil moisture, moderating soil temperature, and adding nutrients as the mulch breaks down slowly.  When mulch is applied it should be at a 3 to 4 inch layer in the landscape beds and mulch rings around trees.
