The Difference Between Promoting Proper Plant Health Care and a Misdiagnosis July 16, 2015
Diagnosis is an important step in discovering which tree and plant pests, diseases and other problems are affecting your landscape’s health and beauty. So, what makes a plant material sample good and helpful vs. not-so-helpful?
Davey’s Debbie Miller, senior diagnostician and plant pathologist at the Davey Institute, discusses what she looks for in a good plant sample. Here are Miller’s 7 Steps to Collecting a Good Tree Sample:
Step 1: Contact an Arborist for Help. If you see shrub or tree leaf spots or discoloration, bark splitting, or other signs of disease and insect infestation, contact your local professionally trained arborist to investigate your plant.

Frozen in Time? February 7, 2012
After the fluctuating mild temperatures we've experienced recently, I was shocked to see my oak tree covered in ice the other morning.
Icicles hung from the branches, thawing as the sun began to rise. My eyes followed the glistening ice crystals and water droplets down the trunk and into the ground above the roots.
That got me thinking: How do freezing temperatures affect my trees? Of course, water is essential to life, but does this necessarily apply to the winter months as well? Or are trees and other plants just frozen in time and forced to wait for replenishment until spring arrives?Read More
