The annual elm-pruning ban is over until March 31, so it’s time to remove dead wood that can attract elm bark beetles, says the Society to Prevent Dutch Elm Disease (STOPDED).
The beetles breed and overwinter in dead and dying elms but trees can’t be pruned between April 1 and Sept. 30 because the pests are drawn to the scent of the fresh pruning cuts.
STOPDED recommends hiring a professional arborist such as an ISA Certified Arborist. Pruned elm wood must be properly disposed of by March 31 by burning, burying, or chipping.
