Japanese Horn Beam Dying

Asked May 15, 2020, 8:52 AM EDT

For the second year in a row, one of the Japanese Hornbeam trees that Friends of Trees team planted in my parking strip is dying. They thought it might be a fungus in the soil, but as they do not have a certified arborist, they suggested I contact you. Parts of the tree look healthy, but certain branches are losing their leaves (drying up, turning brown and falling off). The affected areas are increasing. A new Japanese Horn Beam in our adjacent parking strip seems to be doing fine. Thanks for any assistance you can provide.

Here's information about hornbeam issues:

It's likely the canker diseases. The drainage and growing conditions are likely different than the neighboring tree and it is more stresses and susceptible to the disease.

I would prune out the dead and dying branches and wait and see what happens.

Good luck.

Thank you!
