Willow trees prefer a balanced fertilizer with low nitrogen content. Nitrogen is the primary nutrient in most fertilizers, and too much nitrogen can stunt the growth of willow trees. The other essential nutrients are phosphorus and potassium, which are important for healthy root growth, flower and fruit production, and overall plant health.


In addition, willow trees need small amounts of other trace elements such as manganese, zinc, and iron. In general, willow trees need a slow-release fertilizer with a ratio of 10-10-10. This ratio means that the fertilizer contains 10% nitrogen, 10% phosphorus, and 10% potassium.


This ratio provides an ideal balance of nutrients for the trees and encourages healthy growth. When applying fertilizer, it is important to follow the directions on the package and apply it evenly around the tree at the correct rate.
