THE PROCESS

The Ziehler Approach for Year-Long Results for Trees and Shrubs

 

Tree Care
Step 1
Nutrient Management

Fertilization in the Fall to boost soil health to grow strong and vibrant trees and shrubs.

Step 2
Key Insect Control

Trees and shrubs need insect care just like lawns. We treat common pests like Japanese beetles and cool/warm season mites.

Step 3
Key Disease Management

We treat the most common culprits like apple scab, rust, needle cast and leaf spot to suppress existing issues and prevent new disease from developing.

THE BENEFITS

Top Tier Trees and Shrubs

Our seven-application approach spans across the three growing seasons and includes:

  • Dormant horticultural oil insect suppression is applied in early spring to nourish trees and shrubs to good health
  • Fungicide disease suppression is applied in April and May to ornamental plants susceptible to apple scab, rust, and leaf spot
  • Foliar insect, mite control and disease suppression is a late spring treatment expected in May and June to combat caterpillars, cool season mites and foliar feeding insects
  • Early summer foliar insect and mite control is applied between June and July to suppress Japanese beetles, bagworms, warm season mites, and foliar feeding insects
  • Mid summer foliar insect and mite control application is applied between July and August
  • Late summer foliar insect and mite control application is applied between August and September for fall webworm, mites and foliar feeding insects 
  • Fall root zone fertilization is applied between September and November to deciduous and evergreen trees and shrubs to correct yellowing foliage, repair summer stress and strengthen plants for winter

  • I noticed my specialist didn’t spray all of my plants? Why are they skipping some?

    We use Integrated Pest Management (IPM) techniques, meaning treatments are only applied where they are beneficial and necessary. Our Tree & Shrub Specialists are arborist-certified and trained to identify which plants require treatment and which should be left untreated based on the specific needs and health of each tree or shrub.

    This targeted approach allows us to reduce unnecessary product use while providing effective insect and disease control. By understanding plant biology and potential risks, our specialists can make informed treatment decisions that help protect the long-term health of your landscape.

  • What insects and diseases affect trees and shrubs in Ohio?

    Trees and shrubs can be affected by a variety of insects and diseases, including mites, scale, beetles, fungal diseases, and other plant health issues. Regular monitoring and preventative treatments can help identify and address problems before they cause serious damage.
