When fertilizing and watering a tree, where should the fertilization occur?

Fertilizing at the drip line of a tree is considered the most effective method because this area corresponds to the outer edge of the tree's canopy, where the absorption of nutrients occurs most efficiently. The roots that take up nutrients and water generally extend well beyond the trunk into the area where rainwater drips off the leaves. This method ensures that the fertilizers are applied where the majority of the tree's feeder roots are located, allowing for optimal uptake. By targeting the drip line, you also minimize the risk of burn or damage to the tree that can occur if fertilizers are applied too close to the trunk, where roots may be less abundant and more sensitive to concentration. This practice promotes healthy growth and supports the overall well-being of the tree.
