Saskatchewan bans elm tree pruning from April to August to curb Dutch elm disease spread.

Saskatchewan has implemented a ban on pruning elm trees from April 1 to August 31 to prevent the spread of Dutch elm disease, a fatal fungal disease carried by elm bark beetles. The ban discourages pruning during this period when beetles are most active, though complete tree removal is allowed with proper disposal of the wood. Pruning outside the ban period and proper wood disposal are encouraged to protect elm trees.
