If You Don’t Fertilize Now, You Will Regret It Later

  • Do the bold colors of spring and warm sunshine energize you?
  • Are bulbs and buds beginning to “pop” in your landscape?
  • Or are you seeing signs that winter took a toll on some of your trees and shrubs? 

Now’s the time to apply fertilizer to improve soil composition to fortify the plant and aid the development of new growth.

a common misunderstanding 

By adding fertilizer to the soil around plants, one is not "feeding" the tree. This is a common misunderstanding. Fertilizers offer the tree additional tools to enhance the natural production of their own food. In most cases, the occasional application of small amounts of fertilizer to trees can result in a more vigorously growing tree.”

Healthy trees and shrubs are built on healthy soils.  Unfortunately, the soil in our landscape is usually quite different than the soil in a plant’s natural environment.  When we remove leaves, woody debris and other organic matter from our yards, we disrupt the natural nutrient cycling our trees and shrubs rely on for energy production and growth. Without the nutrient cycle, soil is depleted of several key ingredients for healthy growth.

ArborTech’s aim in soil management is to create conditions that are most favorable for trees’ and shrubs’ growth and that mimic their natural habitat.

Here are a couple of ways our arborists improve soil conditions:


Fertilizer - ArborTech has the tools and equipment to fertilize via sub-surface application (a process which utilizes a probe that goes 6-8" below the soil and uses water as a carrier of the needed nutrients, bio-stimulants and soil conditioners). Fertilizer, applied in the spring and fall, is a great way to promote, growth, vigor and help strengthen your trees and shrubs.  Optimal time is April/May and Sept/Oct.


Root Zone Management - Aeration, irrigation, and the addition of soil amendments (i.e. loam, mulch, organic matter, pelletized lime) can recreate a healthy forest floor optimal for growing conditions. The physical characteristics of the soil are just as important as the chemical characteristics.  Optimal time is April/May.

Yellowing leaves means poor nutrition

The most common symptom of poor nutrition is yellowing of the leaves (a.k.a. chlorosis).

Chlorosis is primarily a lack of iron which is needed in the production of chlorophyll.  Your plant may also be deficient in magnesium, zinc, nitrogen and/or proteins. Chlorosis is typically caused when leaves do not have enough nutrients to synthesize the amount of chlorophyll a plant needs to thrive and be vibrant.  

ArborTech’s tailored fertilizer programs help promote the production of chlorophyll.
