If you’re the owner of a birch tree in an area that lacks rain like Nevada or California, you’re probably already well-acquainted with the bronze birch borer beetle, whether you know it or not. They are a species of beetle that have already caused the demise of thousands of birch trees, often without the tree owners even knowing about it until it was too late. This species of beetle can infest a tree for years before the owners start to notice symptoms which is what it makes it so difficult to safe a tree that is already so close to the brink of death.

As always, prevention is the best way to deal with these bugs. Keep an eye on your tree, make sure they’re as healthy as they can possibly be. And not just because that is generally important, but also because it will lower the risk of infestation. The way in which the bronze birch borer beetles operate, is by nesting their larva into the callus tissue of the tree of which they feed.

A healthy birch will then be able to produce enough callus at a quick enough rate to kill off the larva. However, a sick or stressed tree won’t be able to which will put it at a higher risk of repeat attacks. This will eventually mess up the tree’s transport of nutrients and thus, kill its roots. And as we all know, a tree with dead roots is a dead tree.

To avoid all of this, you should plant your birch in cool and moist soil and in a spot where it will still be able to catch enough sunlight to flourish. Then, once every or twice a month, you should slowly deep water your tree so its soil will keep up a healthy level of moisture. Another good and important way to uphold this, is through mulching. Now, when it comes to fertilization, less is definitely more. Too much fertilization will lead to excess nitrogen which will boost succulent growth which in turn attracts bronze birch borer beetles like nothing else. And while we are on this topic: do not, fertilize when your tree is already showing symptoms of an infestation. It is best to talk with Tree Service in Bay Area CA, so that they can diagnose the symptoms of an infestation. These are:

• Dead or dying branches
• Thinning and yellowing leaves
• D-shaped exit holes that leak reddish sap
• Die-back in the upper part of the tree, making its way downwards
• Bulging in the bark where larvae are tunneling through

Not only will the tree service know what to do but it will help you have healthy trees on your property.

Testimonials

We hired Arborworks to remove 10 trees at our new house. There was a small overgrown forest going on. I don’t think anyone ever trimmed anything in this yard! Not only did they remove the trees and ground the stumps, they also took out our other items we had cut down ourselves.The biggest tree was almost three stories, you could see it towering over the house from the front and we have a two story house. Could not believe how efficiently they cut down that monster tree. Their guy who was in the tree – WOW he made it look easy but I know that it wasn’t! Knew what limbs to cut and where the limbs were going to fall. Was very impressed! We were there when they took all the trees out and I can tell you they definitely know what they are doing. They asked if we wanted the chips/mulch from the stump grinder otherwise they would have taken it away.I would hire them again in a heart beat and I’ve already recommended them! Great prices and GREAT service.
