Save Your Ash Trees!

Cedarburg is within the zone recommended for treatment by the State Dept. of Agriculture. The City Forester recommends treating your Ash Trees with imidacloprid.

  • Homeowners can purchase Bayer Advanced Tree & Shrub at local garden centers. Follow label instructions.
  • Or hire an ISA Certified Arborist. A list of Arborists in our area can be found at Trees Are Good.org - click on “Find a Tree Care Service”.

Smaller trees (less than 12″ in diameter) can be treated with a soil application such as Bayer Advanced Tree & Shrub or a soil injection of Imidacloprid by a certified Arborist.

Larger trees (12″ + in diameter) should be treated using a trunk injection method.

The City Forester recommends the Direct – Inject QC Trunk Injection System manufactured by Arbor Systems, Inc.

This is the method that has been proven successful in saving Ash Trees in Michigan.
