Abstract
If not caught early, slime flux (bacterial wetwood) create unsightly stains on and disagreeable odors around a number of Idaho trees, typically cottonwood, willow and elm. Worse, it can also kill trees, particularly mountain ash, aspen and poplars. Learn the symptoms of slime flux (primarily vertical streaks of discoloration), the microbes responsible for it and the practices you can undertake to keep it from harming any of your trees in this two-page publication, an entry in University of Idaho Extension's Green Thumb How-To's series.
