Question
Hackberry
I have been looking at a sick Hackberry that I can't determine what's wrong with it. I think it's a bacterial infection of some kind but not sure. It is approximately 36"dba and surrounded by a concrete patio. Root flares are good. Has 3 main branches. Two are dying and one is ok. It has these round spots that are now oozing. We are in a drought with 105+temps. Have additional photos if needed.
AnswerSuzie:
I am unable to tell much from your photo. Often it is difficult to make an accurate diagnosis from photos. You are welcome to send another one if you wish, but be sure to review it on your computer to be sure it is in focus and shows what you wish before you send.
There is indeed a bacterial disease of trees called slime flux or bacterial wetwood that involves an ooze. This disease can affect many types of trees and as you can read, it can occur during hot/dry conditions. Below is a web page that contains a bulletin that I have previously prepared on that subject.

From your description of the dying branches, it does sound as if there is some level of decay within those branches. Most often, the decay, whether it is caused by a fungus or bacterium is slow, yet a progressive situation that is irreversible. At some point, tree removal may become your best option, especially if it or its branches may pose a safety issue for person or property. To get an accurate tree health assessment, you should consider contacting an arborist in your community (check yellow pages)or contacting your local county Agricultural Extension Office. These folks can often come out to your property and evaluate the tree "in person". They have an office in each county, usually in the county courthouse building. There is usually no fee associated with an Extension visit.
