An arborist might recommend tree injection therapy for treating diseased or pest-infested trees in your garden.

Tree injections cost $10 per inch of the tree’s diameter. For an average-sized tree, you are likely to pay $50 – $75. It may cost up to $200 to inject a large tree.

Tree injections are effective treatments for lots of common elements. You will see a fast improvement in the health of the injected tree.

How Much Do Tree Injections Cost

Size Of The Tree

The larger the tree, the more you pay. The average cost of a tree injection is $10 per inch of its diameter.

An older tree will have a larger diameter than a young tree. Therefore, you will pay when the older tree gets a tree injection.

Type Of Treatment

Trees get different types of infections. For every tree infection, there is an injection. How much you pay depends on the condition treated.

Depending on the treatment required, your tree may require more injections. More injections mean that the tree gets more medication.

The higher the quantity of medication injected into the tree, the higher you pay.

Labor

Depending on where you live, different arborists have different rates. In addition to the injection, you have to pay for labor.

The higher the labor rates in your area, the higher you pay for your tree injection.

Frequency Of Treatment

Sometimes, it takes a long time for treated trees to get better. Therefore, the tree will require several injections before you can see signs of improvement.

The longer it takes to treat the tree, the more you will pay for its treatment. More time for treatment means more injections for the tree. You will have to pay for every injection your tree gets.

Only a professional arborist can determine the number of injections needed.

Number Of Trees

You will pay more if you have many trees that need treatment. Also, the cost of treatment will vary depending on the size of the tree.

A large tree may need more injections to treat. You will pay more if you have many large trees that require treatment.

How Do Tree Injections Work

Tree injection is like an IV for your tree. You can use tree injections to treat diseases and repel pests and insects.

Tree injection is administered directly onto the trunk of the tree.

First, the arborist will dig a hole in the trunk to remove the bark of the tree trunk to create space for the injection. The bark may be too hard for the needle to go through.

The arborist will then place an injection in the hole. It ensures that the injected drugs go directly to the vascular structure of the tree, to the roots, leaves, and stems.

Tree injections work faster than other tree treatment methods. You can inject medication or fertilizer into a tree.

Types Of Tree Injections

Micro Injection

Microinjection on a tree uses a small needle to inject a range of chemicals and treatments into the tree.

You will drill a small hole in the tree, place a port, and pass the needle through it into the tree.

When injecting a specific part of the tree, use micro-injections.

Micro Injection

Macro Injection

Macro injections derive their name from their use. Microinjection needs a single hole on a specific part of the tree to deliver small amounts of medication or nutrients.

A macro injection is when you have many ports on the tree. Its location allows it to inject more nutrients or medication into a tree.
