Q.Why Is My Waxleaf Ligustrum Ailing?
The upper half of this plant’s leaves are all browning, and some leaves are drying out completely. I increased watering frequency and quantity but it had no effect. Is this a fungus? or a problem with the roots? Thank you.

Unfortunately, your photo did not come through. I am unable to diagnose the issue at hand. I would guess that overwatering has lead to fungal infection. You may need a fungicide. This article will help:
