Why Should I Fertilize My Tree?

In this video, Dr. Dan Herms, Vice President of Research and Development at the Davey Institute, shares why we should fertilize trees.

When trees have a nutrient deficiency, we try to correct that by mimicking the soil environment found in a natural forest setting. In our backyards, we often collect the leaves, twigs, and fallen bark which disrupts the recycling of the nutrients. We also often plant trees in tight places and surround them with turf grass which can outcompete the tree for nutrients.

The type of fertilizer you decide to use is important too. We use formulas designed to slowly release nutrients steadily over time as well as different formulas for different regions. This mimics the natural cycling of nutrients in the forest. 

Tree fertilization has its value as part of a plant health care program. It can be nuanced and it’s important to understand the science behind this topic.
