Umbrella Tree

Question

I’ve had an umbrella tree for over 25 yrs. The conditions seem fine but the plants leaves are dropping off, still green and healthy. Watering is fine and lights ok too. It’s like the plant is dying as quick as it grows. Also, no pests. Any idea what could be causing this? Someone suggested root rot. Is there anything I can do to save this tree?

Answer 1

I am leaning towards it being a fungus of some kind. There are several that could cause this. If it were root rot, you would see yellowing of the leaves before they fell. Treat the plant with a fungicide and, if possible, improve the air flow around the plant to help discourage fungus growth.
