Q.What Is Wrong With My Plumeria?
I’ve had it since September as sticks that I planted. A few months ago it produced the below two leaves. I’ve been watering it about every 2-3 weeks. Yesterday when I went to move it outside, the small leaf was still attached but curled. This afternoon when I went to check on the plant, the small leaf had dropped off. The larger leaf now has brown spots. The pictures are from the top and bottom sides of the leaves.

It appears to have been overwatered, leading to infection!
This can happen when the soil is not allowed to dry out, thoroughly, down to at least 2 inches between waterings.
Treatment will consist of a fungicide/bactericide and keeping all infected growth removed and away from the plant.
