Plant Canker Damage

Canker is a disease that damages the woody tissues that move water and nutrients through the plant. Tree Canker symptoms can appear similar to root rot but damage is more limited. Tree Canker symptoms will be die-back at some point on a branch or if it occurs in the trunk, an overall decline in the tree. The active pathogen can be bacterial (most commonly fire blight) or fungal. Many plants are susceptible to Plant Canker. Fruit trees, roses, leyland cypress, and some common ornamental shrubs are often affected. The actual plant canker will be seen as a sunken, discolored section on a branch, or possibly an oozing wound. The only treatment is to prune out infected branches 1 1/2" to 2" below the canker. Prune only when conditions are dry. Sterilize pruning shears after each cut by dipping them in a solution of 1 part bleach to 3 parts water to avoid spreading infection. Be careful not to damage branches and trunks. Be aware that the tree canker disease is easily spread from branches rubbing together. Our tree and shrub program will minimize stress due to damaging insects and disease. We will also improve overall health and vigor with proper fertilization.Please feel free to call any time you have questions or concerns or contact us.
