If a plant dies from slime flux it should be safe to remove it and replant with another clematis. With any luck, the plant will then re-shoot It is sometimes possible to save an affected clematis by pruning out the stem below the point of slime production. According to the Royal Horticultural Society, pruned stems may fail to reshoot and ooze a sticky substancethis is known as slime flux. However, protecting plants from strong winds and frosts, and taking care when digging and working around them, may help Answer: My best guess (and it is only a guess, since I am basing it solely on your description) is that it could be slime flux. It can be difficult to prevent the stem damage that leads to the development of clematis slime flux. A range of bacterial species, as well as other organisms such as yeasts and fungi, are often found within the slime, all taking advantage of the sugars within the sap. Gasses are also produced which force the slime out under pressure and may result in further stem splitting. Foul-smelling whitish-to-pink, thick, slimy. The sap released in the process can attract. Bacteria and yeasts from the surrounding air and soil penetrate cracks in the bark, feed on the sap and build up pressure inside their host by fermenting the sap and exacerbating the wound. The slime, or flux, is likely to kill both the bark and any other plants (including grass) which they flow on to. The bacteria penetrate deep into the stem tissues, and when the sugary sap rises in spring this is fermented by the bacteria to produce the foul-smelling slime. On woody climbers such as Clematis, you will notice wilting and yellowing leaves or a failure to leaf in spring. Slime flux form most commonly in Spring, where rising sap emerges from fissures in a damaged bark of woody plants, in this case Old Mans Beard, Clematis vitalba. Infection may also sometimes occur through the root system Any factor that injures the stem can lead to the problem developing, for example Īny type of mechanical damage (including strong winds twisting the stems) The disease can be fatal, but plants can sometimes be saved by the pruning out of affected parts.Ĭlematis: clematis slime flux develops when a damaged part of the stem becomes colonised by bacteria that normally reside harmlessly in the soil or on the stem surface.
Damaged areas of stem are colonized by bacteria, leading to wilting, dieback and the appearance of a foul-smelling exudate from the stem.
Clematis slime flux is a bacterial problem that can affect most old Montana species.
