It’s now time “to start taking the dead wood out of your elm trees,” says Janet Feddes-Calpas, executive director, Society to Prevent Dutch Elm Disease (STOPDED). The only time it is legal to prune elms in Alberta is between Oct. 1 and March 31.
“This is when the elm bark beetles, responsible for spreading the deadly DED fungus, are not active,” said Feddes-Calpas.
But it is important to properly prune trees and STOPDED recommends using a professional arborist. Pruned elm wood should be properly disposed of by burning, burying or chipping by March 31.
