Slime Flux and Traginops irroratus at base of mature Chestnut Oak ? #875659
Asked July 02, 2024, 1:05 PM EDT
Sizeable chestnut oak in my neighborhood that has moist, darkened area at base. Affected area is attracting many Traginops (my best guess with the help of google), ants, etc. The ground is wet at the base beneath the damage area but not around the entire tree. Generally, the tree is still pretty firm but there are some spots that you can push in and squish with your finger (I have a video but couldn't attach). From what I've read slime flux won't kill a tree and may "fix" itself depending on extent of rot and if stressors can be eliminated; however, there is some concern that the tree is compromised and this problem would open the tree up to other issues. Wondering how much the slime flux (assuming that is even the correct diagnosis) affects the tree's overall structure since it is in a residential area and very tall. thank you for your input

Expert Response
Slime flux microbes can ferment sap flowing from a wound, including on trees experiencing stress, but it's hard to say from the photos if this tree is suffering from any serious conditions. We recommend having a certified arborist assess it in person (or two, if you want to get a second opinion). Even though they cannot cure every condition, arborists can also look for sources of tree stress from its immediate environment, like girdling roots, that might be able to be addressed.
