Slime Flux and Wetwood

List of files and visuals associated with this text.

Symptoms: Sap seeps out of pruning cuts or other wounds and flows down the trunk, resulting in a malodorous "slime flux." Slime flux may sometimes cause wilting and browning of the tissue between veins of leaves.

Cause: A bacterium causes slime flux. It enters wounds in the tree and causes a wet interval rot of the trunk wood (wetwood). The liquid in the trunk ferments and builds up pressure until the pressure forces it out through openings such as pruning wounds.

Control: Contact a tree care professional to drill a deep hole about 1 foot below the slime exit point and force a piece of plastic pipe into the hole. The pipe should be long enough to carry the drip free of the trunk and root crown.
