Trees and shrubs showing discoloration in the leaves, short annual twig growth, excessive dead wood, or sparse foliage can many times be treated through root feeding. Even if these common signs of stress are not present, root feeding is the number one way to ensure continued tree and shrub health over time. Root feedings are best applied in spring and fall. During this process essential nutrients are injected into the soil and absorbed through roots, providing the plant added vigor and protection against disease harsher times of year. Fall root feedings are beneficial as the tree continues growing and absorbing nutrients long after the leaves fall and then again well before the leaves appear on the trees. A spring root feeding helps to weather the stress of summer heat and drought conditions which are becoming more prevalent as our climate changes.
