Hi everyone,
It is almost July here in Los Angeles (too late in the season to repot) and I am having lots of trouble with a Chinese elm that was gifted to me in April in nursery soil.
Tree showed signs of black spot and was loosing leaves so I defoliated completely and sprayed with neem oil and anti fungal copper spray, drenched the tree. Sprayed like this for two weeks, once a week.
Tree recovered mostly and after two weeks is showing lots of new growth. However, Im on week three and these leaves shown in the palm of my hand are new leaves showing sign of black spot.... the other photo is from before I defoliated.
should I defoliate again and repot? July seems like a rough time to repot plus I just defoliated two weeks ago.
The tree is in partial sun shade and I am watering twice a week throughly.
