How to prepare for the emerald ash borer

Pointers from Minnesota tree experts


Today, Agweek published an article titled "Own an ash tree? Follow these tips." It's a list of practical pointers that may help ash tree owners as they decide how to deal with the emerald ash borer in their landscape.

The Minnesota experts don't recommend treating an ash tree with preventative chemicals until the borer has been identified within 15 miles. They also caution that tree owners should beware of scam artists who want to sell expensive, useless treatments.

You might want to print the article and keep it, if you find the tips helpful. Internet news articles sometimes become unavailable after a few weeks.

Enrich your life with the study of trees.

"The power to recognize trees at a glance without examining their leaves or flowers or fruit as they are seen, for example, from the car-window during a railroad journey, can only be acquired by studying them as they grow under all possible conditions over wide areas of territory. Such an attainment may not have much practical value, but once acquired it gives to the possessor a good deal of pleasure which is denied to less fortunate travelers."

Charles Sprague Sargent (1841-1927)
