My area has been in drought conditions for a few years. The mandatory water restrictions that followed have stressed out the Chinese flame trees growing along my parkway, so much so that they started oozing sap. It didn’t help that some of the pruning that my city did this year were very close to the trees’ roots. I noticed honey-like sap coming from my trees a few weeks ago. I suspected some type of infection and today, the city’s tree expert called me and said that the trees are not in any danger of dying (thankfully), but they do have a bacterial infection. He said I am to water the trees every other day for a week and to use a balanced fertilizer along with it. I will also be allowed to water more frequently henceforth. I asked him about the drought playing a role in my trees’ plight, and he said it was likely a factor. I suspect that the trees are infected with something called bacterial wetwood disease (https://extension.tennessee.edu/publications/Documents/SP631.pdf).
I am grateful to have caught this infection early and will treat it as recommended, particularly to help heal the vulnerable wounds that may become targeted by insects and/or birds that may worsen the problem, and in fact, these wounds are likely vulnerable to even worse tree infections. I hope that watering and fertilizing the tree will, indeed, be the right medicine for these fine trees.
