Diseases

When plants are challenged with unsuitable environmental or physiological conditions, they become susceptible to pathogens that can cause disease.

Signs of Tree Health Problems

Poor soil

Soil composition and structure are basic building blocks for the health of every tree. Urban soils often suffer from lack of nutrients, poor water holding capacity, and lack of oxygen.

Treating Poor Soil

  1. Stunted/Reduced Growth

  1. Discolored Foliage

  2. Thinning out of the canopy

  3. Cankered stems

  4. Death of individual branches

It takes all Three

It takes all three factors for a disease or pest to infect a tree:

  1. Pest - Disease or a pest must be present

  2. Host - The tree needs to be a suitable species for the pathogen

  3. Environment - The environment needs to be suitable for the pathogen or pest to thrive
