We have a yaupon holly on the SWt side of our home and the bark is splitting. What causes this and how can I fix it? We have 2 yaupons but only one is having issues at this time.
We recently lost a 40 yr old crab apple tree due to a beetle, we used a systemic liquid and it seemed to help but not enough because after 80 mph winds two huge limbs came down and tree had to be taken out. Is there a possibility that the yaupon has the internal beetle as well?
The yaupon is at least 15 years old.
I would appreciate your input in this matter.
