I have a Jaboticaba tree, now three or four feet in height and about one year old, in our garage under a sun lamp and developing a powdery substance on its leaves. I am in NJ zone 7b. It is late October. I generally water from above and it is planted in a pot with drainage but it is level, meaning the top roots are not above the dirt. I would say top leaves look like they are developing what looks like a looks “powdery mildew.” I do not want this exotic to die and would love for it to eventually flower and fruit…..though I do only have ONE tree.
1. How to improve its health?
2. How could it ever bear fruit?
Any advice it helpful…Gina, NJ

Powdery Mildew is usually easy to identify.
Usually caused by damp conditions and lack of air flow.
Treat the plant and perhaps adding some air circulation in your garage area may improve the damp conditions. Don't aim it directly on the plant.
Here are some links for you.
