Hi all! I've been browsing the forum here, so I can see it is full of people in similar conditions, but I believe that my predicament is somewhat different than what I've seen covered already.
So, one month ago, I purchased a nice, healthy looking chinese elm. Keeping it indoors, I noticed that leaves started to drop after about a week, which is what I had expected. However, much to my dismay, the leaves continued to drop. The leaves are very discolored when they drop; they are gray at the tip and fade to yellow then to green at the base. I have noticed a faint grayish residue on the leaves, but I had just chalked that up to minerals from my tap water precipitating out as the water dried off the leaves.
The tree is still throwing healthy new growth, so I believe that the watering/fertilizing regime is alright, but some of the new growth has turned gray and shriveled like all the rest. I have begun treating the leaves with neem oil, but I am not seeing a drastic improvement.
Are there any other methods I could try to revive my bonsai?
Thanks for reading!
