I was recently given a variegated boxwood bonsai but within a week the leaves started turning brown and many are falling off. It has quickly degraded and I am afraid of loosing it entirely.
It shows no signs of bugs.
I've made sure its well watered.
I moved it to a cooler area, and in both places it had mostly indirect sunlight but quite a bit of light.
It hasn't been excessively fertilized.
I don't know why its fairing so poorly. The only thing I can think of is if there was root damage when it was transplated shortly before I got it, but the person who did it is experienced and that doesnt seem likely.
Any ideas? Whats causing it? What can I do? Any help would be greatly appreciated.
