HOW WE TREAT INSECTS & DISEASES
INSPECT & DIAGNOSE
A Certified Arborist will evaluate the trees and shrubs on your property and propose a custom plan to treat any insect and disease issues. If needed, we will utilize a local horticulture laboratory to analyze tissue samples from your tree to identify the insect or disease.
APPLY TREATMENT(S)
We will execute the plan by applying treatment to each tree indicated on the plan. This may require multiple visits throughout the year to ensure the best possible outcome for your tree.
MONITOR
Enjoy your landscape throughout the year! Monitor your trees and give us a call if you have any questions or concerns! If you would prefer we monitor your property throughout the year, consider our Integrated Tree Health Management Program!
