Just like all living things, trees need the right nutrition to survive.  And if you want your trees to do more than just survive, they need the right nutrients in sufficient amounts to thrive.  Ideally, trees would naturally receive all of the nutrition that they need from the soil without any supplementation.  However, that is rarely the case especially in populated areas where soil depletion is common.

A tree that is undernourished is at a much higher risk for a number of problems including disease and insect infestation.  Trees that don’t receive proper nourishment will not live as long as properly nourished trees either, and they will more susceptible to root, growth and strength problems.

Fertilization is the easiest way to ensure that your trees receive the proper nutrition that they need.  To understand how to fertilize your trees and what fertilizers to use, first you must understand the function and types of fertilizers.

There are two kinds of nutrients, macronutrients and micronutrients.  Macronutrients are needed in much larger quantities than micronutrients are. 

Macronutrients required for optimum tree growth include:

  •  Nitrogen
  • Phosphorus
  • Potassium
  • Calcium
  • Magnesium
  • Sulfur

Micronutrients required in small amounts for proper tree growth include:

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

Most soils already contain sufficient amounts of these micronutrients to meet the needs for optimum tree growth.  However, adding the macronutrients to your soil in the form of a fertilizer can have significant impact on the health of the trees.

The more urban your environment, the more likely it is that your trees need supplemental fertilization.   Soil in urban and suburban areas is more susceptible to low moisture levels, soil compaction, and competition with other plants for vital nutrients.  If you live in one of these areas, it may be well worth your while to look into fertilization for your trees.  Though trees that are unhealthy or lifeless can be a strong indication of the need of fertilization, a soil test is the best way to determine the specific needs of your trees.
