Using mulch in the landscape is one of the seven steps or principles of xeriscape design. Mulch helps conserve water by reducing evaporation from exposed soil surfaces. Be sure to use the correct mulch type and depth for the site and plant type.
Roots of some very drought tolerant plants do not tolerate too much soil moisture. Avoid using organic mulches around these plants.
