Tree fungus can be a dangerous disease that can affect the health of your trees. To protect your trees, it’s important to know what type of fungus is growing on your tree so that you can properly diagnose your tree. Here are some of the most common tree fungi to watch out for on your trees.
If you suspect that one or more of your trees is suffering from any type of tree fungus, it’s best to call a professional arborist to come out and diagnose your trees.
Girdling roots are when a tree’s roots wrap around themselves and cut off the water and nutrients a tree gets. Root girdling is common, and can kill your tree. Although it is common, it is not natural, as girdling is caused by environmental issues in urban settings.
The most common cause of root girdling is improper planting or transplanting of the tree. Trees that spend too much time in pots can get girdling roots. The roots keep growing but have nowhere else to grow, so they wrap around themselves. This can also happen when a tree is planted in a hole that’s too small.
It’s important to keep this in mind when planting a tree too close to foundation or a sidewalk, as this can also impede the roots from growing naturally. Leaving pieces of the container in which the tree was grown in can also affect the growth of the roots later on down the line.
You can tell if your tree has girdled roots by checking the trunk for an abnormal flare. Normal trees have trunks that flare from the ground, but trunks with girdled roots have skinny trunks. The leaves will also show signs of distress, such as early leaf drop and canopy dieback.
Prevent a tree from getting girdling roots by digging a large enough hole for the roots to grow. The hole should be about three times as large as the root ball. Do not put mulch right up against the trunk. If the root ball is encircled around itself, make sure to break the root ball up before planting it.
If you think your tree may be suffering from girdled roots, contact a professional arborist.
