Is my tree dying?

Asked October 16, 2018, 10:23 AM EDT

We have an older flowering crab apple tree in our back yard that developed a hole in its trunk at the furcation of it's branches. We saw info online that says to try and cover it to prevent water from getting to it and not to fill it with anything. However the hole seems to be going deeper into the tree trunk, something like mold is growing and the wick is very soft almost mushy. Otherwise the tree appears healthy. What can we do to help it to heal? We really want to keep it! Thank you for your time!

We viewed your photos. This looks like a type of heart rot in the cavities of the tree. There is no treatment. The tree will eventually decline and you will have to consider removal. For an onsite diagnosis regarding the health of the tree you may want to contact a certified arborist to make sure it is not a hazard. http://www.treesaregood.org/
