Categories of Tree Diseases
Tree diseases can be broken into 3 main categories:
- Bacteria & Viruses
Within each of these categories there are assortments of different diseases (of varying severities) that can afflict your trees. Different species of trees are prone to different diseases. Let’s explore each disease category in more detail below.
How can I tell if my tree has fungus?
It’s important to note that not all fungus is hazardous to a tree’s health. In fact, some will actually benefit the tree. With that being said here are some signs to look for to see if your tree has fungus.
- Powdery mildew
- Tree cankers and anthracnose (dead areas and growths between live tissue and bark)
- Wilting leaves
- Tree rust (white, yellow or red spots on leaves, branches or trunk)
If you notice any of these signs, contact a tree care professional to ensure the fungus is not harming your tree. Treatments can typically be as simple as applying an anti-fungal agent.
How can I tell if my tree is infected with bacteria or a virus?
Did you know that trees get sick too? Viruses and bacteria are most commonly transmitted to trees through an external source (or vector), like an insect or even fungus.
Here are some signs to look for if you think bacteria or a virus has infected your tree.
- Leaf spots and yellowing
- Leaf scorch (dead tips surrounded with yellow discoloration)
- Stunted growth
- Slimy wetwood
Tree bacterial and viral infections can be treated with help from a certified arborist. Contact us today if you notice any of these signs with your tree.
How can I tell if my tree has parasites or pests?
Insects and trees live in harmony for the most part. However, when trees are weakened (like during a drought), certain insects can have a devastating effect on the health of a tree. Not only can they carry certain bacterias and viruses, they can eat and bore into the tree itself.
Bag worm, locusts, mites, aphids, gypsy moths and more can cause irreparable harm your trees.
Look for these signs if you think your tree may have a parasite or pest problem.
- Holes in or damage to the trees trunk and main branches
- White liquids oozing from damaged areas of tree
- Irregular “shiny” looking bark
- Sudden loss of leaves
While identifying pests can be easy, treatment can be difficult. Professional arborists will know how to eliminate the pests in a way that doesn’t harm the tree or other creatures that live on it.
