Winter Pruning for Black Knot and Fire Blight

Very few people think of pruning in the dead of winter, but it is probably the best time to prune diseased trees that are infested with black knot and fire blight.

Winter pruning is no different than pruning at any other time of year. You want to remove the 3 D’s, the dead, diseased and damaged branches and material. “The beauty of winter pruning is that there are no leaves, and you will have a clear picture where to prune,” says Toso Bozic, woodlot extension specialist, Alberta Agriculture and Forestry.
