This treatment helps trees prepare for or recover from stress related to construction damage, drought, insects and disease. It also helps improve a tree’s overall health by strengthening its root system and creating a denser canopy. This is accomplished by redirecting the tree’s energy away from twig growth and toward other areas, including root and leaf development. This exciting new treatment will help save and improve many trees that may have otherwise been lost.
Although species vary, vegetative growth can generally be reduced by approximately 40 to 60% over a three-year period after just one treatment. However, growth reduction within the first year of treatment may not be as noticeable as in subsequent years.
Root System Enhancement
Plant growth regulation can increase the fine root density in species including oaks, elms and lindens. This results from the re-allocation of carbohydrates from the canopy that are not needed for vegetative growth.
Improved Drought Tolerance
Drought is a major cause of tree death and decline, especially in urban landscapes. Research has shown that plant growth regulation increases drought resistance by helping trees reduce water losses during hot, dry periods.
Increased Tolerate to Death and Disease
Plant growth regulation changes some important physical traits of leaves. Some of the more notable changes include increased leaf thickness and hairs as well as thicker leaf cuticles. These changes tend to improve water status of leaves and may present additional physical barriers to pathogen invasion.
