Why Trees Need Fertilization
Trees need food to grow, in addition to air, light, and water, and most of that food comes from the soil. In a natural forest setting, fallen leaves decompose and return nutrients to the soil, feeding the next generation of growth. Residential yards interrupt that cycle: when leaves are raked up and removed, those nutrients never make it back into the soil, which is why periodic fertilization becomes necessary.
The 16 Essential Elements Trees and Shrubs Need
Healthy trees and shrubs require 16 essential elements: carbon, hydrogen, oxygen, phosphorus, potassium, nitrogen, sulfur, calcium, iron, magnesium, manganese, boron, copper, zinc, molybdenum, and chlorine. Carbon, hydrogen, and oxygen come from air and water, while the remaining elements must come from the soil.
Macronutrients — nitrogen, potassium, phosphorus, calcium, magnesium, and sulfur — are needed in larger quantities, while the rest are micronutrients needed in smaller amounts. A shortage of any one of these can show up as reduced growth, poor color, or general decline.
Why Lawn Fertilizer Isn't the Answer for Trees
Lawn fertilizer can actually harm your trees and shrubs. Many lawn products contain broadleaf weed control agents that are harmful to broadleaf plants like trees and shrubs, and lawn fertilizers are typically formulated with nitrogen levels that are too high for tree health.
How Eden Tree Pros Fertilizes Trees and Shrubs
