The Benefits of Trees
Trees provide so much more than shade. Here are a few reasons trees are important, courtesy of the International Society of Arboriculture (ISA):
- Air-conditioning costs are lower in tree-shaded homes & businesses; heating costs are reduced.
- In workplaces with trees, people report decreased workplace stress and fatigue.
- Cleaner air: leaves filter the air we breathe by removing dust and other particles.
- Cooler environment: trees reduce heat in and around parking lots and paved areas.
Trees and the Drought
California residents are being asked to lower their water use by 15%. One easy way to do this is to turn off your sprinklers. But wait! What happens to the trees? Although they may look okay for now, the stress of going without water will take a toll. Lawns can be easily replanted and replaced, but trees take many years to become established.
What do Trees Need?
How Should I Water My Tree?
There is no “silver bullet” on how often or how much to water. This depends on many factors. Instead, after you water, take a shovel (away from tree roots) and check your soil. How deep did the water penetrate? Then check again several days later, a week later, etc. Make sure water is reaching the top 18” of the soil, then water again once soil dries out somewhat.
