Q.

I Have Just Repotted My Indoor Banana Plant With Recommended House Plant Soil, But I Wondered If John Innes No. 2 Would Be Better?

My banana plant has wilted after reporting help should I use John Innes no.2 soil? Also I have other banana plants with black spot; what is the best anti fungal treatment for this please? This photo was taken a couple of days a go but much more wilting has happened.

No I believe that soil would be too nutrient rich for the plant. It sounds like they all have the same underlying issue, though... overwatering.

Make sure that your container has plenty of drainage to allow all extra water out. They should never be allowed to remain in fully saturated soil.

Make sure that the soil dries out completely down to about 3 inches before watering again. If the container has no drain hole then you will need to let it dry out almost completely down to the bottom between watering.

You will want to treat with a fungicide as well. These articles will help:
