How do you know if your tree has a disease?

White spots on trees & Shrubs. Leaf spots on leaves or needles of trees or shrubs. Thin or stunted trees or shrubs. Another sign that your tree has a disease is peeling off the bark.

The tree's bark is important as it protects the inner core of the trunk and keeps the tree healthy. If tree bark begins to peel, trees may not maintain the necessary nutrients and could die. Keep in mind that many trees normally experience small amounts of shelling bark. However, if you notice larger pieces of bark falling from your tree, call a local Beverly tree care company for help.

If your tree has wilted leaves, pay attention. The leaves are the farmers of a tree, who collect sunlight and process it into food energy. But if they wither, they don't work at full capacity, and the whole tree suffers. If your trees aren't stressed by heat or drought, leaf wilting may mean something different.

If you have flooded soil that doesn't drain well, wilted leaves may be an indication. In this case, the lack of oxygen causes wilting since too much water is drowning the leaf tissue. How can you distinguish between leaves on trees that wither from heat or drought stress and those that wither from excess water? While both conditions cause leaf tips and edges to brown and die, leaves stressed by heat and drought will be browner and drier overall, while overwatered leaves will be soft and loose. Other causes of leaf wilting include diseases, such as fire plague, which appears during hot and rainy spring weather.

The fire pest is a bacterial disease that affects plants of the rose family, including apple and pear trees. Infected leaves wither and look burned. Do tree leaves have dark spots, strange colors, or a distorted shape? Learn how to detect, identify and combat leaf diseases in trees. Get started on diagnosing tree diseases with our illustrated summary of 10 common tree diseases.

Full details on visible damage and control measures accompany each image to help you understand what your tree is worried about. Canker is a tree disease characterized by a dead area located on a trunk or branch. Cankers are caused by mechanical damage inflicted by a lawn mower to environmental stress, such as frost, crack, and sunburn, to fungi and bacteria. One of the easiest to identify signs of tree disease is changes of color in the bark.

If you notice fungi on the bark of trees growing on your tree with white or black spots on the bark of the tree, these are clear signs that your tree should be examined by a professional. Cracked, shelled, crumbled, brittle or fluffy bark are also signs of an unhealthy tree. Tree diseases can develop anywhere on the tree or even throughout the tree. Trees show signs of common symptoms of leaf spots and spots, scabs and blisters, defoliation, needle plaster, and even yellowing.

Stem canker and root rot are also common. Prune the tree to promote better air circulation and cover well with mulch to prevent fungi from splashing off the ground. The fungi, or “cones,” that grow in the tree's bark mean that the tree is currently decaying, and these fungi use nutrients from decaying wood to grow. There are many reasons tree leaves wither; it may be a problem that is easily fixed or a larger problem that requires treatment.

However, by learning what signs to look for in our trees, homeowners can realize that an unhealthy tree could cause property damage. He recommends that homeowners and business owners inspect their property for any obvious signs of decaying trees and call the certified arborists at Cicoria Tree and Crane Service. Jennifer from Beverly asked about her sick birch: "I have a birch tree in the front of my yard that is always dropping limbs onto my lawn. Is this normal?" If your tree is falling more than an occasional branch, and if these branches are large, it's time to examine it.

You may need to repeat the test on several areas of the tree to determine if the entire tree is dead or only a few branches. A key difference in identifying the fire pest is that it first appears at the beginning of the growing season and affects only the part of the tree that has been infected. Trees that lean more than 15 degrees from vertical are generally indicative of wind or root damage. If your tree tilts suddenly, it could be a sign of serious damage and be at risk of falling.

This is usually just temporary cosmetic damage that will not seriously harm your tree since beetles will fly to other trees, and caterpillars will turn into butterflies after a few weeks. Alternatively, you may have a fungal problem if the leaves turn spotty or brown after the rainy season.
