Symptoms
On very old woody Clematis montanas, you will notice wilting and yellowing leaves or a failure to leaf in spring. Foul-smelling whitish-to-pink, thick, slimy ooze may be apparent at the base of the stem/trunk or in a puddle on the soil.
What we know
Clematis slime flux is a bacterial problem that can affect most very old Montana species. Damaged areas of stem are colonised by bacteria, leading to wilting, dieback and the appearance of a foul-smelling exudate from the stem. The disease can be fatal, but plants can sometimes be saved by the pruning out of affected parts.
