Landscape Report: Slime flux (also known as wet wood) is a dark, smelly and unsightly sap from tree trunks (fig. 1). The disease is not usually a serious problem but the appearance can be alarming. Slime flux is caused by common surface-dwelling bacteria or yeast fungi that enter the trunk through wounds associated with improper pruning, stem breakage, injections, cracks from freeze damage or weakened crotch of the feet. Bacteria and yeast can live on sap nutrients inside damaged trees for years without any external evidence.

Symptoms The main symptom is the appearance of dark sap oozing out of the tree which occurs when the gases produced by the growth of bacteria and yeast cause the internal pressure of the sap to become high enough to force the sap out. through cracks in the skin. Dark streaks usually turn gray or white when dry. The emerging sap may be foamy and white at the point of discharge. Airborne bacteria, yeast, and fungi often live in wet leaking material, producing and releasing foul odors. Slime flux can delay wound healing (callus formation).
American Elm Tree Producing Sap For First Time #794091
Slime flux is common in mature elms (fig 2), oak (fig 3) and mulberry; and less visible in maples (fig 4), paper birch, sycamore, and walnut.
Prevention There is no control or treatment for slime flux. Inserting a drain tube into the tree to relieve pressure and drain the infected sap was once an accepted treatment, but is no longer recommended and can do more harm than good. Drilling holes in affected trees causes internal spread of bacteria within the tree and may allow entry of wood-rotting fungi.
To reduce the chances of prone to developing wet wood, avoid unnecessary damage to the tree and branches. Proper pruning techniques, HO-4-W, will allow branches to heal faster. Make sure susceptible trees receive good general care; including watering as needed and mulch to retain moisture and keep mowers away from the tree trunk. Avoid excessive traffic in the tree root zone to prevent soil compaction and root damage.
The first and most important step for managing a tree disease is to accurately diagnose the problem. The best approach to diagnosing tree problems is to start by submitting tree photos through the digital upload tool on the Pest & Diagnostic Lab (PPDL) website. In the case of slime flux, it is not practical to collect the type of physical sample needed for confirmation so photographs are the best alternative.

Rarely in the spring, you may find an orange, slimy substance slowly oozing from a wound in a hardwood tree. It is a fungus or a complex of fungi and yeast that boils in the sap that drips from the wound of the tree. The main fungus involved that gives this slime its orange color is
This old dogwood in Tennessee has large branches that have died and broken off. The oozing sap from the pruning wound became colonized with Fusicolla orange slime, which began to flow down the trunk.
Here’s a close-up of the amputated limb, and as the sap rises in the spring, the fungus colonizes the oozing sweet sap.

Fusicolla orange slime starts from a wound on a river birch tree growing at the State Botanical Garden in Clemson.
Although this slime looks a little disgusting coming from your prize hardwood tree, it’s actually harmless. It is very similar to wetwood or slime flux, which is caused by either bacteria or both bacteria and yeast. Orange slime fungi only grow on carbohydrates (sugar) and moisture in sap, but they do not cause diseases in wood or tree leaves. These fungi thrive in the spring as sap rises and oozes from wounds in trees or branches.
In March of this year, a river birch at the State Botanical Garden in Clemson was found to have a minor sap infection by Fusicolla orange slime.

I recently came across a tree with a white bubbling liquid slowly oozing from its bark, and had no idea what it was.
Why Is Sap Dripping From My Magnolia Tree?
I saw two flowing birch trees in the river while camping on a lake island in Southern Indiana. The scientist in me immediately went to work, but not to Dr. Google, at least at first. I think it’s good practice to observe and brainstorm before getting the instant gratification of knowledge. This helps keep the cogs moving. It’s also my aversion to technology outside of excursions. But mostly because I don’t have my own smart phone. Brainstorming time!
My campers and I debated about what caused the fluid – was it an infection, a defense mechanism, a symbiotic relationship, a natural cycle of the tree. Beer always helps with these discussions. So are campfire jam sessions. I highly recommend both.
The foamy liquid is like water, not too slimy or viscous. I came closer and smelled it — I remembered cheese. Okay, I thought, we have mold. Interestingly, in the same trees that showed bubbles, there were bullet holes. Important?
We drank and sang and had deep scientific discussions. Maybe we did a little more of the first two. However, on the boat ride the next morning, I spent some time wondering if those trees were going through the natural metabolic process of the tree, or if they were sick from an infection or injury, or both.
Peaches Oozing Clear Sap
When I got to the nearest googling device that day I typed “white foamy fungus on a tree” and, voila, the term slime flux came up. I’m not as far off as I’d hoped either – brainstorming success before googling!
Slime flux, also called wetwood, is a general term for the water-soaked portion of deadwood within living trees that occurs in both deciduous and coniferous trees. Fluid is usually seen oozing from a crack or wound in the tree, giving the skin a wet appearance. The cause of wetwood, however, has been attributed to a number of things. Many sources (for example, here and here) claim that a range of bacterial infections are the cause of the waterlogged state; others say that the infections may be secondary; that flowing fluid is a fertile ground for bacteria, yeast, and fungus, but the presence of water is due to internal causes or water flow.
However, they are present, either through the roots or through the wound, the microbes are present under the skin of the fermentation of sugars due to the decrease in oxygen content, which causes an increase in carbon dioxide. The gas accumulates in the trunk and increases the internal pressure, resulting in the gas escaping from the weakest points of the trunk. This explains the lump I saw. Other fermentation products, such as acetic and butyric acid, can cause pungent odors, which will explain the smell.
The bad news is that there is no treatment for wetwood. Arborists used to recommend holes in the trees to let the gas out, but then it was determined that exposing more heartwood could do more harm than good.

The good news is that wetwood, or slime flux, will not usually kill a tree and is actually quite common. Unhealthy trees will not benefit from the infection, however. Injured trees are more susceptible to falling slime flux. It makes sense. If you have an open wound, opportunistic bacteria will usually be in abundance. Moral of the story: maybe it’s not a good idea to use a tree for target practice, but it made for a great science adventure.

Coutts, M. P. & Rishbeth, J. Formation Of Wetwood in Grand Fir. European Journal of Forest Pathology 7, 13-22 (1977). While running the trails in Monte Sano after several days of steady rain, I noticed a foamy substance on the cut trees. In a tree, there is a bubble of foam at the base of the tree, and a sml amount of clear water appears to drip from the bark immediately above the bubble. On another tree, foam appeared to be coming from the bark about 3 feet above the base and seeping down the tree. Any idea what it is? Thank you –
