PLANT GROWTH
Plant Growth Regulators for Tree Health and Size Maintenance
At Heartwood Tree Care, we believe in caring for the whole tree — from the roots to the canopy — and, sometimes, this means slowing a tree’s growth for its own good. We do so with Cambistat, a plant growth regulator (PGR) that is scientifically proven to improve the health of trees.
As Cambistat gently slows tree growth, it allows the tree to redirect some of its energy to produce defense chemicals and enhance fibrous root growth. The resulting benefit of the reallocation of energy is improved tree health and durability. With our tree and plant growth regulator services, you can enjoy a green, vibrant tree that is better able to withstand drought, disease, insect activity, and other environmental stressors common in Charlotte, Lake Norman, and Asheville, NC.
Use Growth Regulators to Improve Tree Health for:
Construction injured trees
Declining and older trees
Trees stressed from drought
Trees growing in limited rooting areas
Trees injured by disease or insects
Use Growth Regulators to Control Tree Size for:
Trees too close to houses
Trees near pools, decks, patios, and sidewalks
Trees under power lines
Trees that are blocking scenic views
High-maintenance trees

A Closer Look at the Benefits of Cambistat Treatment
Growth Reduction
Cambistat is designed to gently and predictably slow the growth of your trees. You can expect a 40-60% reduction in growth over a 3-year period. Cambistat should be reapplied after three years for maintenance.
Higher Tolerance to Insects and Diseases
Research shows that Cambistat makes trees significantly tougher in response to some opportunistic insects and diseases. It does so by thickening the protective barrier of the leaf and increasing the production of defense chemicals.
Improved Drought & Heat Resistance
Drought is a major cause of tree death and decline in the urban landscape. Research shows that Cambistat increases drought resistance by helping the tree to decrease water losses during dry, hot periods.
Root System Enhancement
Research shows that Cambistat increases fine root density. This is important because higher root density increases a tree’s ability to absorb minerals and water. With more access to essential nutrients, the tree is able to produce more energy and survive in stressful situations.
How Plant Growth Regulators Restrict Tree Growth
How exactly do tree growth inhibitors slow down a tree’s growth without harming it? Unlike harsh chemical treatments or drastic pruning, Cambistat works internally to alter the tree’s hormonal balance, shifting energy away from rapid expansion and toward root development and overall resilience.
When applied by Heartwood Tree Care’s ISA-certified arborists, the plant growth regulator is delivered directly to the root zone in a soil drench. The tree absorbs the active ingredient, paclobutrazol, which then moves upward into the canopy. There, it suppresses gibberellin biosynthesis. By reducing the production of the plant hormone gibberellin, Cambistat effectively limits cell expansion and shoot elongation so that the tree focuses instead on developing a strong root structure for enhanced drought resistance and increased defense against diseases and pests.
