How To Fertilize Your Trees

Fertilizer provides a source of essential nutrients that plants need to grow naturally and be healthy. While trees can get nutrients from the decomposing organic matter, certain nutrients may be lacking. For young shrubs and trees in the landscape, consider applying fertilizers to improve color and appearance. This post sheds more light on how to fertilize your trees.

1.  Apply the Right Quantity of Fertilizer

Tree fertilization depends a lot on the age of the trees. Very young saplings have sensitive roots and trunks. Therefore, these require small applications of quick-release fertilizer. The developed trees can handle standard fertilizers, and thus, fertilization may be done two times a year and preferably during the growing season.

The mature trees have intricate root systems that are widespread, which means the nutrients intake is more significant than the younger trees. The mature shade trees do not require nutrients as the young trees do therefore; fertilizing the mature trees twice a year is sufficient.

2.  Understand the Different Fertilization Methods

Choosing the appropriate method of fertilizing shade trees requires some understanding of the different approaches applicable. Here is an overview of the other fertilization methods to apply to your garden trees.

  1. Compost: commonly referred to as decayed matter, compost is the most common plant fertilizer. The decayed organic matter acts like mulch, and it is also a natural fertilizer. Decayed plant matter provides the healthy growth and development of a tree.  However, the plants take longer to absorb the nutrients because the organisms that live in the soil must process the decayed matter.
  2. Organic Fertilizer: this refers to the plant and animal-based non-compost material. The organic fertilizer is the least harmful to the environment and the tree itself. However, the release of nutrients is slower as the soil’s microorganisms must decompose the organic matter.
  3. Inorganic fertilizer: this is the most common choice for homeowners looking to provide the trees the right amount of nutrients. The inorganic fertilizer is inexpensive and absorbed much faster compared to organic and compost fertilizer.

3.  Perform soil Analysis Before Fertilization

Ideally, soil analysis provides a few essential pieces of information. The soil test will inform you of the soil PH, the macronutrient content, and recommendations for amending the soil. Knowing the existing levels of nutrients is essential to avoid over-fertilization. Note that applying excess fertilizer can be bad for both the tree and the environment.

4.  Talk to an Expert

When it comes to tree care, hiring an expert provides multiple benefits. First, the experts will conduct all the necessary tests to ascertain the correct amount of fertilizer to apply to the trees. This way, cases of over-fertilization do not occur. Also, an expert knows what type of fertilizer to use throughout the different stages of tree growth. Overall, you save on cost, while the trees are looking good and healthy all year long.


We have looked at how to fertilize trees.  The proper technique includes applying the correct type of fertilizer, proper pruning, and watering. The tree care specialist will also advise on the right kind of pesticides to use on your tree.  Therefore, you do not have to worry about it. Always engage the services of a professional when it comes to tree care.
