With their large, stocky base, oak trees are often preferred in landscapes over pines. But like all tree varieties, even oaks are susceptible to disease, illness and stress.
So if you have one or more oak trees in your the yard, refer to the following tips on how to keep them healthy.
Oak bark should maintain a brown-greenish appearance. If you discover areas of discoloration, it could be indicative of disease, in which case you should attempt to remove the affected area.
Of course, this isn’t always an option, especially if the disease has spread across the entire oak tree, or in the upper parts where it’s not easily accessible. But if you see a small section of branches that’s discolored, it’s best to go ahead and remove it.
Another tell-tale sign of a diseased oak tree is the presence of shelf mushrooms. These fungi form in the shape of shelves on the tree, often scattered diagonally across the bark.
Shelf mushrooms should be removed with the affected area treated with an application of neem oil or some fungicide to prevent further damage to the oak tree.
Oak trees typically require minimal pruning, making them an excellent choice for homeowners and property owners who don’t want to invest a significant amount of time into their lawn upkeep.
However, if you see dead, diseased or otherwise distressed branches, you should prune them. Allowing them to remain on your oak tree only increases the risk of further damage. This is why it’s best to err on the side of caution by removing them.
In addition to pruning away bad branches, fertilizing an oak tree can also help by keeping it healthy and disease-free. Check with your local plant nursery for recommendations on a well-balanced fertilizer that’s tailored for oak trees.
Watch for Insects
Although hearty, oak trees may succumb to various insect infestations. Some of the most common insects that infest oak trees include galls, aphids, caterpillars, lace bugs, twig pruners and leaf miners.
The key to minimizing the damage caused by these infestations is early detection. The sooner you spot the infestation, the sooner you can take action. Contact a tree expert for more information on how to rid your oak tree of an insect infestation.
These are just a few tips to keep your oak trees healthy.
