WLWT: Beautiful pear tree causes ugly invasive problem

But this tree from Asia tended to split at its trunk, so growers introduced other varieties that cross-pollinated with Bradford pear trees and began producing seed-bearing fruit.

Soon, the pear trees were showing up in disturbed patches of forest and along highway edges in Ohio and other states.

An Ohio law went into effect last year making the selling, growing or planting of Callery pears illegal statewide.

Culley said homeowners might consider replacing pear trees in their yards with native plants.

"A lot of people really love their tree," she said.

One alternative is to spray the tree with plant-growth regulator treatments available at home and garden shops that inhibit a tree's development of fruit, she said.
