Capital Tree Service takes a holistic approach to tree care following the principles of Plant Health Care (PHC). PHC is a comprehensive and holistic approach to manage the health, structure and appearance of landscape plants and trees. In the past problems in the landscape were often reactive in nature, PHC attempts to prevent problems before they occur. Our highly trained Certified Arborists (ISA, TCIA, and/or BCIT Certified Arborists) know that trees cannot be viewed in isolation – they are dynamic living beings – elements of a landscape that includes soil, grass, shrubbery, and hardscape. They interact and sometimes compete with other plants for light, food, water, and space.
