Growth Regulation

A group of chemicals called plant growth regulators has become available to arborists. These chemicals were developed by power companies to reduce the need for line clearance pruning by limiting canopy growth. Energy normally reserved for growth is redirected to the root system by these chemicals.

The results of repeated applications are:

• Increase in fine root development
• Thicker, greener leaves
• Reduced water stress
• Reduced shoot (twig) growth
