The picture you are seeing at the top of this page is taken from one of the banana plants that I brought last month to my home garden. When I bought it from the local nursery the plant was fine. I planted it in the ground and after a couple of days I noticed the black spots on my banana leaves.
In this article, I will tell you what causes these black spots on the banana leaves and how to cure them.
The issue has been reported on gardening forums and communities multiple times by multiple gardeners. I find out that this happens mostly after transplanting it or repotting.
What causes banana leaves to have these black spots?
Take a look at the other pictures.
Banana leaves black spots
On this type of banana plant, it is absolutely normal to have dark marks or black markings on the leaves.
We usually identify "Dwarf Cavendish" banana plants with these black spots. (Especially the Musa variant)
You can also notice this issue in a few other dwarf banana varieties.
It's also a characteristic of the G9 banana plants.
I started hating the internet to resolve the gardening issues. I could not believe my eyes that so many websites are giving us treatment for this specific issue not even knowing this is a normal phenomenon.
If you see the black spots on regular banana plants (not the dwarf), then only you have to worry and look for treatment.
Generally after repotting, transplanting, or changing the location the plants go stressed. When they will adapt the new environment, they will be fine.
If you notice darker black spots on regular banana plants, buy any fungicide made for banana plants and apply.
Do not forget to read the application instruction on the package.
In general, overwatering can show symptoms like stem rot or yellow leaves. Only black spots are an indication of fungal infection. (I am ignoring rare bacterial infections)
