Plant Growth Regulators

 

When the wrong tree has been planted in the wrong place and is getting too large, plant growth regulators may be applied to dramatically decrease its growth rate.  These products are also used to treat stressed trees and trees with root damage.  By decreasing stem growth, the tree can allocate its resources to the production of defense chemicals and root development.

 


 

Trunk Injections

 

Occasionally, a tree cannot be fed by a traditional soil injection method.  This could be due to the fact that a tree has paved surfaces surrounding it or otherwise has inaccessible roots.  In these circumstances, we use micro-capsule trunk injections.  Also, in the rare occasion that a highly toxic pesticide is required, we recommend injection to avoid environmental exposure.
