I purchased this Bonsai from a big box retailer a few weeks ago and can't seem to ID this tree. It looks similar to a boxwood but I'm not completely sure. Also I've been out of the office for two weeks and when I came back I noticed leaves dying. I'm assuming it's from lack of water so I watered it and made sure to soak it until water came out of the hole on the bottom. About an hour later the leaves in the pictures that are yellow turned brown and fell off. I assumed if it was due to lack of water they would perk back up instead of turning brown.
I don't know the last time this tree was fertilized as I purchased at a big box retailer. So I'm thinking that may be an issue as well?
I didn't find the right solution from the Internet.
