Tar Spot

Tar Spot is one of the most common problems affecting maple trees. Although it can affect all maple trees, it most commonly encountered in Norway maples. Tar Spot is a fungal infection that affects the surface area of the leaf and normally shows up in the early summer. Due to the fact that it is simply a number of black spots on the leaf, it is easily identified.

The spots start out about 1/8 of an inch in diameter, but continue to grow. The spots are initially light green and yellow, but slowly over the season turn black. Tar Spot is often worse when the summer season is wet.

Although the disease rarely will cause any serious damage to the tree, it can seriously affect the aesthetic value. The only way to completely eradicate the infection would be to remove all the infected leaves each fall from the area. However, this will only work if everyone in the area also removes their infected leaves. Since it is unlikely that all the leaves in the area will be removed, it is a problem that can only be maintained.

The infection itself can be reduced by thinning the branches of the affected tree. This allows air flow, which keeps the leaves from having high moisture content. As a result, the fungus which needs moisture to thrive will not be able to spread or grow, at least to the same extent.

Tree Health and Hazards
With a cold winter season upon us it is easy to forget
about one of our most valuable resources, and that is
our trees. Trees maintain clean air, provide shade in
the summer, and natural wind breaks in the winter.
Tree health, though often forgotten, is a vital part of
property maintenance. It is important to remember
that unhealthy trees can be dangerous and costly.
The homeowner is responsible to maintain and
monitor the health of their trees. With this in mind,
one can ask oneself, how do I inspect my trees?
There are a few options, a good starting point
would be to inspect the trees yourself, looking
for dead, dying, or hanging branches, cavities, or
holes. However, you can also call in a professional
arborist to inspect your trees. The best part about
calling a professional arborist is that the quotes and
consultations are free.
Trees add value and character to your home and
deserve the best possible care.
