There are many situations in the urban environment where slowing or reducing the vegetative growth of plants can be beneficial to the plants and to the properties they grow on.
Plants Near Infrastructure
The conflict between the ‘grey’ and the ‘green’ infrastructures in urban ecosystems is well documented, often causing damage to both parties. There are many different scenarios where a growth regulator can help extend the useful lifespan of trees and shrubs and help meet the needs of the property owner.
Mature Size Maintenance
When a tree or shrub is young, our practices often focus on promoting healthy, vigorous growth. As that plant matures, there may come a time where reducing and maintaining a consistent size is more desirable. Growth regulation can help keep those plants fitting in their locations for longer.
Rapidly growing trees and shrubs can create large gaps between leaf nodes and create an undesirable ‘leggy’ appearance. Reducing growth with a growth regulator can promote a more desirable compact appearance.
There are two different growth regulators to utilize depending on the type of plant being treated: Cambistat®, which is used for trees, and Trimtect®, which is used for shrubs, vines, and groundcovers. Cambistat is applied to soil and may be applied anytime that this ground is not frozen or saturated with water. Trimtect is applied by foliar spray and may be used during the growing season.
