Understanding Tree Nutrients and Their Impact on Healthy Growth

You might know that all trees require sunlight, water, and nutrients to grow, but do you know what the most essential tree nutrients are and what they do? In this short guide, we’ll go over the key macronutrients and micronutrients for trees so you can understand their impact a bit better.

Why Trees Need Nutrients for Healthy Growth

All tree species grow and thrive when they have optimal access to the nutrients they require. Nutrients help them carry out photosynthesis, building proteins, and many other tasks. Plants and trees need and utilize various nutrients to carry out all their basic functions.

Each nutrient affects different processes, but the two main types of nutrients that trees and plants need include macronutrients (what plants use more) and micronutrients (what plants use in smaller amounts). A common rule of thumb is to utilize one pound of fertilizer for every 1,000 square feet of land, but you can always ask your local tree care professional.

Types of Macronutrients That Trees Need

You can perform a soil test to see what nutrients your trees and plants potentially lack. Trees primarily use six key macronutrients: potassium, phosphorus, nitrogen, calcium, magnesium, and sulfur. Let’s examine how these tree nutrients support healthy growth:


Nitrogen is the most essential nutrient for tree growth, making up the chlorophyll that impacts plant color and the photosynthesis process. It promotes the growth of stems and leaves in trees, which turn yellow when they lack nitrogen. 


Magnesium also forms part of chlorophyll, a vital component in photosynthesis. A lack of magnesium can decrease plant growth and the greenness of tree leaves. It aids with cell division and transports phosphorus within plant tissues. 


Phosphorus helps trees convert the sun’s energy into valuable compounds that they need to thrive. It also helps with the production of tree roots and seeds. The reproductive cycle depends on these tree nutrients as they’re essential for replicating DNA. 


Sulfur is vital for multiple stages of tree growth and activates many vitamins and enzymes a tree needs. 


To keep up with tree health care and pruning, ensure your trees have enough potassium, too. Potassium helps trees use water for growth and improves drought resistance.


Calcium improves tree strength and durability and supports plant cell walls and membranes.

Types of Micronutrients That Trees Need

Although trees require fewer micronutrient quantities, they still are important for their functions. Key micronutrients include:

  • Copper
  • Chlorine
  • Cobalt
  • Boron
  • Zinc
  • Manganese
  • Molybdenum
  • Iron
