Trees can elevate a plain yard to a shady, green oasis. When taking care of trees, most homeowners ensure they receive water, sunlight, and occasional pruning. Fertilization services can also be incredibly beneficial to trees; however, many homeowners don’t know when to fertilize their trees.

If you want your trees to be as healthy and resilient as possible, we recommend calling a certified arborist at ArborZone for top-notch tree service in New Braunfels, TX.

Benefits of Tree Fertilization

Adding fertilizer can help your trees stay healthy and recover from illness, poor conditions, or pest infestation. Signs your tree could benefit from fertilization include:

    • Discolored or undersized leaves

    • Slow or stunted growth compared to previous seasons

    • Dead branch tips


If you have decided to incorporate fertilization into your tree care, that is great news. When you should fertilize trees depends on your priorities and the needs of the trees you’re addressing. A certified arborist can help you determine the best time to fertilize.


If you fertilize in early spring, begin the process before the tree starts actively growing; this should result in lush foliage during the growing season. Many people also fertilize in early spring because they are already taking advantage of the warm weather by preparing the rest of their gardens and yards.


Alternatively, many people opt to fertilize their trees in early fall. Trees dedicate their resources to developing roots and other important “behind-the-scenes” functions in the fall. Any excess nutrients in the fall are stored in the root system.

Other Factors To Consider

Other factors to consider alongside the time of year are the potential influences on a tree’s health. Considering all these will help you determine the most suitable fertilizer techniques and whether options like slow-release fertilizer might be a good choice for your yard.

    • Age: Fertilizing young trees could overwhelm them. Give the tree several years to establish its root system before adding nutrients to ensure optimal health.

    • Type: A hardwood variety, like oak or maple, will need different nutrients from a fruiting tree or an evergreen.

    • Pests: A properly fertilized tree is less vulnerable to insect infestation and disease. However, if a tree is battling insects or diseases, it may be wiser to address that issue separately.

    • Roots: If a tree’s roots have been damaged by construction work, you should allow the tree time to reestablish its root system before fertilizing.

    • Soil: Performing a soil test to assess the levels of phosphorous, zinc, nitrogen, potassium, and other nutrients in your soil can help you determine what nutrients to add.
