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.

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

  1. Pathogen - Bacteria or a pest must be present

  2. Susceptible Tree - The tree needs to be a suitable host for the pathogen

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