We’re continuing with our series on the effects of grass on trees: Most of us only associate clean air with trees. Grass also cleans our air and is often overlooked. If you’re looking for guidance on how your lawn might be affecting your trees, please don’t hesitate to ask.
Dr. Sylvan Addink, a Certified Professional Agronomist, offered the following comment as part of his executive summary for – Trees Are Sacred, Grass Is Bad, Why? “History is dotted with examples of worthy causes which have been promoted by the use of questionable scientific data and assumptions.
Unfortunately, the errors are often uncovered after it is too late to correct the environmental problems which occur. In many urban water conservation programs there is a perceived difference in the benefits and costs of trees versus grasses. Trees are promoted while all types of grasses are restricted or targeted for removal. This perception is not fully based upon scientific fact but upon impressions and assumptions such as those we get when we see irrigation water running down the gutter in front of our homes each

Trees Are Sacred, Grass Is Bad, Why?
– Sylvan Addink, Ph.D, Certified Professional Agronomist Water Use of Trees Versus Turf
If efficiently irrigated, research data indicates that many trees require as much water, if not more water than grasses. Research by Dr. Devitt et. el. in Las Vegas, NV indicated that “During the active growing season, tree to grass (Bermuda grass/ryegrass low fertility) water use ratios in the range of 2.0 to 4.0 were observed.”
Evapotranspiration (ET) reflects the level of plant water use from both plant transpiration and evaporation. “Leaf area index (LAI), an important structural variable descriptive of vegetation, is directly related to evapotranspiration.”
