Problems With Your Ash Tree?

Over the past few years, the North Texas area has seen much drought. But it’s just now that we are really seeing the effects in our landscape’s established trees. Trees that are stressed from lack of proper watering become more susceptible to disease and pests. Ash trees seem to be under a lot of pressure right now and are experiencing a number of pest and disease problems. If you are noticing sap leaking from the trunk, holes in the bark or splitting bark, defoliation, or brown spots on leaves on your Ash trees, please read on.

One potential culprit is the Red Headed Ash Borer (Neoclytus acuminatus). The redheaded ash borer will attack weakened or newly planted trees. You’ll begin to notice the defoliation at the tops of trees, bark splitting, branches trying to emerge near the base of the tree and small holes in the tree from larvae and insect infestation which will result in sap leaking out.

Another issue we are seeing is Anthracnose. This is a fungal disease brought on the recent rains mixed with warm weather; the perfect conditions for most fungus infestations. You’ll notice brown spots forming on leaves, especially on areas towards the inner branches of ash trees where humidity and moisture is highest. Extreme cases of Anthracnose will cause extensive defoliation of the tree. Properly fertilizing in spring and fall plus application with a preventative natural fungicide are good ways to minimize the effects of this fungal disease.

If you're noticing similar symptoms on your Ash trees, give us a call so we can send one of our certified arborists for a consultation.
