Large Oak Tree Dying

We have a large native oak tree on our property in East Texas. It may be a water oak, but I'm not sure. Two different landscape folks have told me it has what is commonly referred to as "crotch rot". The tree is turning black at the large fork on the main trunk and this black area is wet and has an odor like vomit. I was told the tree could not be saved and we should cut it down (before it gets weak and falls). Any comments, suggestions for this disease?

Others know more than I, but I will give it a shot.

I think a know what you are talking about because I have seen what you described. I believe it is cause when two leaders grow V shape instead of a U shape. V leaders will have decay and debris in the crotch it can be devastating towards the health of the tree. Sometimes problems show up years later. Some I have seen sap stains down the trunk. I think all these problems are cause because of lack of air.That is why when trees are young remove one of the leaders. Now if your trees have U shape leaders, then the trees are in good shape in good long life.

As for your water oak there might be some other suggestions, but mine maybe remove one of the leaders. I know, hate to mess up a beautiful tree as well :roll: .

So you mean cut off half the tree? And then wouldn't the remainder of the tree be suceptible to disease. The area where the two "trunks" fork is probably 4-1/2 to 5 ft off the ground with a diameter of approx 2 feet. So, are you saying just pick a side and cut the other side off? The smelly sappy resin is dripping from the fork down the center of the tree all the way to the ground.

I will try to take a picture of it this weekend and post. Any other suggestions - Howard do you know what this is?

Well, maybe there is another way (better way :? ). Like I said, others know more. Help us "pros."

I wonder....

Could you somehow drill a hole into the tree to provide drainage? Put in a pipe or plastic drain line.

I would also think cutting out one half would work. I don't think you'd make a flush type cut but enough to increase circulation. Does the crotch area get any sunlight? Direct sun might keep it drier. I wouldn't just wait and see because eventually this tree will get sicker and die. Better to destroy it trying to fix the problem. A new tree can be planted ASAP to replace your loss.

Sorry you have to do any of this and possibly loose a gem in your yard.
