Keeping Birch and Olive Trees Healthy: The Power of Soil Injections
Birch and olive trees are cherished for their beauty and the benefits they bring to our landscapes and tables. However, these trees face a common threat from borers; pests that can cause significant damage if left unchecked. Thankfully, there’s a simple and effective solution: soil injections. In this blog post, we’ll explore how soil injections can help prevent borers in birch and olive trees, keeping them healthy and vibrant for years to come.
Understanding Borers and Their Impact
Borers are tiny insects that lay their eggs on the bark of trees. When the eggs hatch the larvae burrow into the tree, causing damage to its inner tissues. This can weaken the tree which will make it more susceptible to disease and other pests. Birch trees are often targeted by bronze birch borers, while olive trees face threats from pests like the olive tree borer. These borers can cause wilting, dieback, and even death if not treated.

These are from different types of borers so the activity will be different. The olive tree borers excrete a yellow-ish substance that is left behind as they burrow into the bark while the birch tree borers leave clean, open holes.
Why Soil Injection?
Soil injections offer a targeted and environmentally friendly way to protect birch and olive trees from borers. Instead of spraying chemicals onto the leaves or trunk, soil injections deliver insecticides directly to the root zone of the tree. This allows the tree to absorb the insecticide through its roots, providing systemic protection against borers.
Key Benefits of Soil Injections:
- Effective Protection: Soil injections target the source of the problem by delivering insecticides directly to where borers lay their eggs.
- Environmentally Friendly: By minimizing pesticide drift and runoff, soil injections reduce the impact on surrounding plants, animals, and water sources.
- Long-lasting Results: Once absorbed by the tree, the insecticide provides continuous protection against borers for an extended period, reducing the need for frequent reapplication.
- Easy Application: Soil injections can be applied quickly and easily, making them a convenient option for homeowners and arborists alike.
When Do We Perform Soil Injections?
We recommend performing soil injections in early March. This is because it is before the borers lay their eggs so the tree will be protected throughout their breeding season.
