Spring is here an so it the possibility of heat stress for trees. We naturally think of ambient temperature as the driving factor. Another is radiant heat, energetic that is absorbed and released by adjacent material like a driveway or retaining wall. A third source of heat stress is reflected heat from shiny surfaces. This is a common issue in urban environments around larger buildings or homes with large windows or other reflective surfaces. A good analogy is the sunburn you might get at the pool or lake, because the sun’s energy is reflected back at you from the water’s surface. Similar damage can happen to trees. Check out this video for a simple example encountered the other day.

Correctly managing trees requires more than a license, insurance and some tools. A strong understanding of tree biology and proper training are essential.
This image is a perfect example of what NOT to do, specifically tree injections done at five feet above grade, rather than at the root flare where dense, vascular tissue is best accessed. Sadly, we regularly see similar mistakes by companies without adequate knowledge or experience. And often, we must explain to a client their tree was damaged by a company that misrepresented their qualifications and gave them bad advice.
A professional arborist has a deep understanding of tree science, properly advises tree owners on appropriate management options, and implements the desired option with skill and integrity. That is the essence of caring for people… and their trees.
