Tree Fertilization – Is it Really Necessary?

Often when we think of fertilization, it’s our lawns that come to mind, not trees. However, like grass, your trees need attention too. Although it’s easy to think of them as self-sufficient, trees are just as vulnerable to illness and pest infestations as any other form of plant life. So, if you’ve ever pondered whether or not tree fertilization was necessary, the answer is yes.

Fertilization is essential to your trees because it protects them from insects and disease. And if you’re having someone come out and apply multiple treatments per year, they can inspect your trees to ensure they are healthy. If they notice any problems, they treat them before they become bigger issues. For best results, you should fertilize your trees twice a year, once in the spring and once in the fall.

Fertilization will strengthen your trees so that they are strong enough to stand up to these infestations and diseases.


Regular tree fertilizer treatments will keep your trees under the watchful eyes of professionals.

Regular fertilization treatments can do more than just supply your trees with the nutrients that they need to grow strong and healthy. When you schedule regular fertilization treatments from experienced tree professionals, they will have the opportunity to regularly inspect your trees to check on their health. If they identify any issues with your trees, they will be able to provide treatment for them as soon as possible, which will limit any damage before the issues become bigger problems.

For example, if they notice signs of an emerald ash borer infestation, they can recommend treatments to cure the infestation as soon as they see them, which can end up saving the life of your trees.


How many treatments are necessary for the best results?

How often you should fertilize your trees is based on multiple factors. For example, the size and health of your trees play a role in how often you might want to fertilize them. Other elements you might also want to consider include the type of insects and diseases your trees are exposed to, along with the condition of your soil.

While tree size, health, and potential threats may necessitate more or fewer fertilizer treatments, the general rule of thumb is to schedule two fertilizer treatments per year—one in the fall and one in spring. In circumstances where your soil is nutrient deficient, it may be necessary to perform additional treatments.

Sometimes its best to feed nutrient-deficient trees through injection fertilization.
