ARBOR-PLUS™ provides a balanced blend of primary and micro-nutrients with ACT®. These promote quicker healing, deep root growth, plus stronger vertical and horizontal growth of trees and shrubs.

In the soil, ARBOR-PLUS™ Promotes aerobic biological activity, helping the soil to breathe which helps to reduce the growth of disease-causing anaerobic bacteria that can destroy roots. Its trace nutrients allow for rapid uptake to develop deep green leaf color, while it supplies essential nutrients commonly lost due to leaching.

ARBOR-PLUS™ is a concentrated liquid that should be diluted in water for quick and easy application as a root feeding solution, soil drench or foliar spray application.

ARBOR-PLUS™ is highly concentrated and should be mixed with water to ensure adequate coverage. Jar test for compatibility prior to final tank mixing with other products. Not recommended for use in fertigation injection systems.
DEEP ROOT FEEDING OF ALL TREES & SHRUBS: Mix 2.5 gallons per 100 gallons of water and inject 1-2 gallons of this solution per inch of trunk (Or as determined by an experienced arborist) into root zone of trees and shrubs and water following treatment. Apply 1-2 times per year or repeat as desired.
FOLIAR FEEDING OF TREES & SHRUBS: Mix 2 quarts per 100 gallons of water and spray onto foliage to point of run-off. For best results apply foliar feeding soon after DRF treatment. Repeat as desired.

Shake Well or Stir Before Use – Not Recommended for use in Fertigation Injection Systems.
