In-Depth: Protect Your Ash
SAINT PAUL, Minn. - Minnesota has one of the largest concentrations of Ash trees in the country, estimated at 900 million. Every one of them is in danger of being killed by this pest. There are treatments available but homeowners need to be careful or they could lose a lot of money along with their trees.
A neighborhood in Roseville is on edge.
One woman says she would like to do something before it spreads too much.
Sixty percent of the shade on this block comes from the lush green canopy of its ash trees. Nobody wants to see the trees cut down. But now that the Emerald ash borer invasion is under way it’s only a matter of time before this menace marches through thousands of neighborhoods and kills millions of trees.
