In Calgary's diverse climate, trees, whether in urban yards or sprawling acreages, can encounter a variety of health problems. Recognizing these issues early on is crucial to providing the necessary care or deciding when it's time for a tree to be removed. This guide walks you through common tree problems, their signs, causes, and effective treatments.
If you're seeing signs of these symptoms, it's important to contact an ISA Certified Arborist like Evergreen LTD immediately to rescue or remove the tree. If left to worsen, the integrity of the tree's trunk and branches may be compromised, leading the the risk of branches, or the entire tree, falling on people or property.
Discoloration of Bark, Branches, or Leaves
Discoloration can be a sign of diseases like bronze leaf disease, which specifically affects certain types of poplar and aspen trees. It manifests as orange or reddish-brown discoloration starting on the outer edges of leaves and moving inwards. Early detection is crucial, and affected portions of the tree may need to be removed​.
Sap Leaking Down the Trunk
Leaking sap can be indicative of canker diseases, caused by fungal or bacterial pathogens. These diseases can lead to the death of branches or even the whole tree if not managed. Treatment involves careful pruning of affected areas and sterilization of tools to prevent spread. It's essential to work with dry bark and seek professional advice for trunk cankers.
Lack of Growth Near Top
This could be a sign of "dieback," which can result from various factors including diseases, pests, and environmental stress. Dieback typically starts at the tips of branches and moves inward. Early intervention may save the tree, depending on the underlying cause​.
Wasps Congregating Around the Foliage
Wasps may be attracted to trees due to aphid infestations or the presence of sap, which can indicate other health issues in the tree.
Holes or Cavities in Trunk
These can be caused by fungal diseases or pests like bark beetles, leading to structural damage. Trees with significant damage or cavities may need to be assessed by professionals to determine the best course of action, including possible removal if the tree poses a safety risk​​.
Brittle Branches
Brittleness, especially if branches break easily, might be indicative of brown rot or other types of decay affecting the tree's structural integrity. Regular inspection for signs of breakage is advised as it can be an early sign of disease.
Excessive Needle Drop
Needle drop in conifers can be a symptom of several conditions, including fungal diseases like brown rot, which specifically affects conifers, making needles drop excessively​​.
Curled or Browning of Leaves in the Summer
Leaf curl is a fungal disease that results in deformed, discolored leaves that may fall off. Treatment involves dormant season spraying with copper or sulfur-based fungicides. While peach trees were specifically mentioned, similar principles may apply to other trees experiencing these symptoms​.
