I have a young Chinese elm bonsai that can't be older than 2 or 3 years. I've had it in more or less the same conditions since early fall. I live in Oregon, and have kept it indoors since october. Planning to take it outside in the spring.
It has been healthy for the fall and started dropping leaves in the winter, which hasn't concerned me. However after a trip over the holidays (a friend was watering it for me) I arrived home and found a fungus growing on the soil surface. Along with this there was a considerable amount of leaf drop (browning fully and partially depending on the leaf). I did a quick repot and made sure that there wasn't any root rot.
Since I repotted I thought it was doing quite well. There has been a lot of buds breaking, which seems unusual for january, but it has been a sunny winter. But today I noticed that the new leaves have slowed growth and are starting to brown on the edges.
Most of the leaves have fallen off the tree, and I'm not sure if these new ones are going to make it. Should I be concerned, or is this standard chinese elm behavior this time of year?
Any help would be much appreciated. I just want to make sure she doesn't die on me!
