Economists, Meteorologists, and Sports Talk Radio Hosts often try to predict future events. Their goal is to help prepare us for these outcomes. Arborists make predictions to help guide tree care advice and avoid unwanted outcomes. Considering past events, local trends and past year experiences here are some highlights of what I predict for the 2019 Tree Care year.

Moisture and Diseases: During 2018 disease issues popped up on a wide variety of trees. Leaf and needle diseases are now very common in the landscape and have spread to nearly every property. Root rotting fungal diseases are also an increasing trend. Trees can be protected with treatments ahead of these diseases. Your Prescription Letters have recommendations as needed.

Uneven Rainfall: From July into August 2018 localized drought caused some areas to look like fall with lots of Maple and Ash leaves piling up in the street. Recent climate trends show overall moisture levels may increase along with temperature. The trend has also been larger storms including flooding with longer periods of no moisture in between. These changes are likely to add stress to trees.

Emerald Ash Borer: During 2018 numerous local forested areas turned leafless with dying areas of ash. Calls came from new clients with previously untreated Ash which changed from seemingly ok (in their view) a year earlier to now untreatable and dying. I predict more noticeable decline and death of untreated Ash trees throughout most of our service area.

Viburnum Leaf Beetle: Look for this insect during April and early May, and watch out. The defoliation of Viburnum shrubs, especially Arrowwood is quick and severe.

Tar Spot: Norway Maples all over were afflicted by this noticeable and unsightly disease. Last year an increased number of Silver, Red and Freeman Maples also showed symptoms. Protective sprays can be used if the amount of defoliation starts to damage tree health.

Needle Cast: Everywhere I look Spruce trees are thinning due to premature needle loss from these diseases. Regular protective treatments when warranted can help to preserve key trees.

As the local weather and climate changes I predict that your Wachtel Arborists are also adapting to these changes. As a team we share our experiences and results of treatments to help determine the best treatment alternative for your trees. All this goes into the Tree Care Prescription letters that you will be receiving soon. As predictions go several surprises are certain to keep us on our toes during 2019, and we look forward to working with you to guide your tree and shrub care needs.

Trees act as a home to a variety of wild life. While most are peaceful residents, there are some that do more harm than good. Certain bugs and insects can either suck, chew or bore through specific trees – causing significant damage that can lead to the death of your tree. Fortunately, there are some precautionary measures that can be taken to eliminate bugs and insects from harming the trees on your property...
