Threat of rain postpones Cary's treatment for hemlock trees

From staff reportsJuly 9, 2014 

— The town has postponed plans to treat trees in the Hemlock Bluffs Nature Preserve from an infestation of hemlock woolly adelgids, aphid-like insects that can damage trees while feeding on their sap.

Workers planned to treat the trees Thursday morning, but the threat of rain caused town leaders to push the project to Monday morning.

Cary plans to keep the park open when it treats the trees.

The town says a recent inspection of its 235 eastern hemlock trees yielded the discovery of hemlock woolly adelgids, which are native to Asia and were last found in the nature preserve in 2010.
