Mayten tree

Asked May 14, 2018, 8:32 AM EDT

My mature 25 year old mayten tree is experiencing signs of dying. 30% of the tree has lost all leaves and branches seem brittle and dying. This has been going on slowly for 4 years. Mushrooms have grown at base of trunk which is another sign of a dying tree. I have fertilized and watered deeply in warm weather once a week. Is this some kind of disease? I’ve read the life span is 50 to 150 years so it it is relatively young. Any suggestion on what I can do to save my beautiful Mayten?

Here’s some general information on the care of Mayten trees:

Watering: 15-20 gallons per week for the first 2 years; 15-20 gallons twice a month for the 3rd year; as needed after 3 years (varies by soil, sun, and wind conditions).

Maintenance: Early pruning needed to train to desired shape; pruning needed less frequently with age. Removal of root suckers. Sidewalk clean-up during seed capsule drop.

Tolerance: Drought (once established), any soil, fog.

Special Considerations: Prefers sun and space. Needs good drainage. Does not tolerate strong or gusty winds. Can be susceptible to aphids during bloom.

Also, Mayten tends to be invasive – do you see any suckers or small trees at the base of the large tree? The suckers and small trees compete with the main tree for nutrients.
