So, you’re looking for a way to improve the health and vitality of your trees and shrubs? Deep root fertilization may be the answer! This can be a great way to give your trees a boost, especially if they seem to be struggling or aren’t growing as well as you’d like them to. We’ll cover everything you need to know in our deep root fertilization guide!

What Is Deep Root Fertilization?

Deep root fertilization is a type of tree care that involves applying fertilizer to the roots of trees and shrubs. This can be done either by injecting fertilizer into the soil or by applying it directly to the roots. Deep root fertilization is beneficial because it helps trees and shrubs to absorb more nutrients from the soil, which can improve their overall health and vigor.

How Is Deep Root Fertilization Different from Traditional Tree Fertilization?

Deep root fertilization is different from traditional fertilization in a few ways. First, as we mentioned, it involves applying fertilizer directly to the roots of your trees and shrubs. Traditional fertilization, on the other hand, generally involves spreading fertilizer around the base of your plants. That way, it’s a much stronger treatment.

Additionally, while basic traditional fertilizing is possible to be done by non-professional, deep root fertilization must be done by Certified Arborists due to the specialized equipment needed for this method.

Does Your Tree Need Deep Root Fertilization?

A tree in distress is the perfect match for a treatment like deep root fertilization. The following are often signs that your tree needs some help:

  • Tree growth is very slow or nonexistent
  • Leaves are smaller than normal
  • Foliage is decreasing
  • Branches show signs of dieback
  • Leaves turn oddly discolored or look chlorotic

If you think these symptoms are present in the trees in your yard, it’s very important to consult a tree care professional. They will best be able to assess the health status and needs of the tree and start a deep root fertilization treatment to help revive your beautiful arbors.

Why Is Deep Root Tree Fertilization So Important?

With so many deep root fertilization benefits, it’s easy to see why the technique is important for the well-being of your trees. First, as we mentioned, it helps them to absorb more nutrients from the soil. This is important because it can help to improve their overall health and vigor.

Additionally, deep root fertilization can also help to improve the drainage of the soil around your trees by reducing compaction and increasing aeration. This is important because it helps to prevent waterlogging and ensures that your plants are getting the oxygen they need.

All of these elements are vital for strengthening the tree’s resistance to disease and also encouraging the growth of its canopy, foliage, and even new sprouts!

How Is Deep Root Fertilization Done?

The most common method is through a root zone injection probe, which involves injecting the special fertilizer blend directly into the soil around the tree’s roots.

In general, deep root fertilization is the best option for landscape trees over traditional forms. This is because it helps to ensure that the fertilizer most closely reaches the roots of the tree, where it can be most effective.

When Is the Right Time for Deep Root Fertilization?

The best time for deep root fertilization is typically in the spring and fall. This is to support vegetative growth in the spring and root growth in the fall. These are not the only times that deep root fertilization can be done, however. As long as the soil is not saturated or frozen, an arborist will likely be able to apply the treatment.
