Can Tree Injections Save My Diseased Tree? Here’s What You Need to Know

Facebook Instagram
If you’ve noticed signs of disease in your trees—discoloured leaves, dieback, or unusual bark lesions—you might be wondering whether anything can be done to save them. In many cases, tree injection is a highly effective treatment that can stop the spread of disease and restore your tree’s health, without the need for major pruning or removal.
At Lancashire Tree Services, we now offer professional tree injection treatments using the Chemjet Injector System, a proven method used to combat serious diseases such as Phytophthora and Sudden Oak Death.

What Is Tree Injection?

Tree injection is a modern arboricultural technique where small, specialised injectors are inserted directly into the trunk of the tree. These injectors deliver a carefully measured dose of fungicide, insecticide, or nutrients directly into the tree’s vascular system—bypassing the need to spray or apply chemicals to the soil.
It’s a fast, precise and environmentally friendly way to treat trees from the inside out.

What Can Tree Injection Treat?

  • Phytophthora root rot
  • Sudden Oak Death
  • Anthracnose
  • Nutrient deficiencies
  • Certain insect infestations

If you have a mature tree that’s showing signs of decline, a targeted injection can help restore it to health—often without the disruption of removing limbs or applying external chemicals.

5 Signs Your Tree Might Need Injection Treatment

  • Rapid leaf loss outside of autumn.
  • Bark splitting or dark lesions appearing on the trunk.
  • Slow growth, thin canopy, or yellowing leaves.
  • Mushrooms or fungal growth near the base.
  • Sudden decline after nearby landscaping or construction.

Why We Use the Chemjet Tree Injector

We use the Chemjet system because it allows us to treat trees quickly and safely with minimal damage to the trunk. Each injector is inserted into a small drilled hole, which naturally seals itself after treatment. This makes it ideal for heritage trees, garden specimens, and trees in sensitive environments like parks or conservation areas.

Real Results for Real Trees

Tree injection isn’t just for big estates or woodland management. We’ve used this method across Lancashire, from private gardens in Lytham to commercial sites in Preston, helping save trees that were once thought to be beyond help.

Many clients begin to see visible improvements in tree health within weeks.

Should I Try a Tree Injection?

If your tree is in visible decline, it’s important not to wait. Some diseases spread quickly and can move between trees, especially in damp soil conditions. A quick assessment by a qualified tree surgeon can determine whether injection is the right option.
