Saluting Branches is a non-profit organization dedicated to honoring veterans by providing tree and landscape care at national cemeteries. Arborists from around the country volunteer their services to help keep these locations safe and beautiful. This year marked the organization’s fifth anniversary and we were proud to participate in it. Take a look at some of the highlights.
Most of us are familiar with the results of drought stress, but did you know that high temperatures alone can cause significant damage to the health of your plants? Given that many areas are recording rising temperatures, we should become aware of how warmer temperatures affect the physiology of plants.
High temperatures reduce photosynthetic rates faster than they reduce respiration rates. The result is an imbalance because the carbohydrates produced by photosynthesis are used faster than they can be replaced. Higher temperatures increase the loss of water through stomates in the leaves, and thereby increase demands on the root system to take up water to cool the tree via transpiration. (High temperatures are usually accompanied by low rainfall—adding insult to injury.) Cellular membranes also become unstable and result in ion leakage within the leaf cellular structure.

Wood boring insects feed on the inner wood (xylem) of roots, trunks, branches or shoots of a plant. While there are hundreds of wood boring species that are not considered pests, some species can cause branch dieback or even mortality. Recently transplanted young plants and stressed plants are most susceptible to attack from wood boring insects. Damage occurs when the larvae of wood boring insects chew through the nutrient and water transporting tubes of the plant.
Serious internal damage is hidden inside tree trunks, roots, and branches.
