Dying Outdoor Ming Aralia

Question

My outdoor ming aralia has been living well for the past five years. It’s planted in the ground and is about seven feet tall. This year, almost all of the leaves have fallen off. I’ve tried fertilizing it, but nothing seems to bring it back. It gets new leaves, then they turn yellow and fall off. What can I do to bring it back to life?

Answer 1

This sounds like it may be a fungus, though could also be thrips (a small insect).

I would recommend treating the plant with neem oil. It will address both fungus and insect issues.
