  • The Difference Between Promoting Proper Plant Health Care and a Misdiagnosis

    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?

  • Frozen in Time?

    After the fluctuating mild temperatures we've experienced recently, I was shocked to see my oak tree covered in ice the other morning.
