I recently bought a young gingko biloba (maidenhair) bonsai from a nursery that looked healthy two weeks ago. I brought it home and have since watered it twice. I put it outside in the day and it gets 1 hour of full sun but is in the shade for the rest of the day.
Since I bought it, the lower leaves have started browning in a weird way that starts from the middle. So far it has effected one leaf very badly and some other leaves are displaying brown spots.
I'm guessing the problem is that I'm overwatering it, but I wanted to make sure I'm not overlooking a larger issue.
I've included a picture of the badly affected leaf and the whole ginkgo!
Any advice would be appreciated!
