to the Rescue! BY MARC DUNIA
alifornia is facing another drought emergency, and 2021 will be a particularly challenging year for landscapes and trees. With water restrictions looming throughout the state, landscapers, arborists, and property managers will need to be prepared for many changes in the way they manage their properties. Finding economical ways to reduce water usage and promote tree and plant health will be a top priority for everyone.

PROTECT SOILS Soils are the foundation of vulnerable root systems. Having healthy soil is the best defense against poor environmental conditions such as drought, hot dry winds, and sudden changes in the environment. Root systems need to be protected from excessive heat, evaporation, and soil compaction. Adding mulch is the easiest and least expensive way to combat these plant stressors and protect root systems.
BENEFITS OF MULCH Mulch is cost-effective and good for the soil. Adding three to six inches of an organic-based product can reduce watering needs by more than 25%. When mulch is added to a landscape, trees and plants greatly benefit. Watering needs are reduced. Microbial and biological activity are increased. Plant growth and development flourish. Other benefits of mulch include reduced weed control, a pleasing appearance, and a nice natural smell. Another benefit of mulch is that it helps to maintain soil moisture, which keeps the plant material hydrated and makes it less prone to damage in the event of a fire. (Incorporating rock or gravel around buildings and fence perimeters can also reduce fire risk.) Mulch provides a layer of insulation that protects roots from excessive heat. Continued on page 22
