The annual ban on pruning elm trees officially lifted Friday. The ban is enforced from April 1 to August 31 each year by the province to limit the spread of Dutch elm disease.

The carriers of the fungus that cause this disease, the Elm bark beetles, are mainly active during those months, and they are attracted to the scent of fresh cut trees that comes from pruning them.

During early September, beetle activity is low, and dying branches are easy to spot, as leaves are still present. This makes the best time for pruning.  It is illegal to transport, use or store elm firewood, due to its ability to spread DED.
