They were attractive, they grew fast and they were cheap to plant but now, Iowa`s ash trees have become an expensive problem.

For many of us, deciding what to do about the approaching emerald ash borer is an unavoidable dilemma. But there is some help out there that could make the choice easier to make.

Ankeny has some 2,000 ash trees on public land and around 20-percent of the total canopy and they`re coming out one by one.

But in residential areas, it`s not so simple.

Over half of the trees in some suburban neighborhoods can be ashes and treating them with a product called 'Tree-Age' is becoming an attractive option.

“Tree-Age is 95%, some studies are saying 99% effective. It`s product is good for two years, and there`s a high probability that the product will be good for three years,” explained Wright Outdoor Solutions Arborist John Griffiths.

On average, the treatment runs around $200 and must be applied throughout the life of the tree. Compare that to the cost of removing a large tree which runs from $1,000 to $2,000 according to Griffiths.

In deciding whether to treat or remove, arborists recommend the National Tree Benefit Calculator website, which can tell how much value an ash tree brings to a property by considering its effect on storm water and energy savings.

According to the calculator, most ashes more than cover their treatment price, but it`s clear that most will likely meet the axe.
