I have black spots on my cassia leaves. I sprayed with garden fungicide and after a few days black spots returned, so i removed them. Is this normal?

It can be for wetter seasons. Along with treating the top of the tree multiple times, I would also treat the soil!

Use DOLOMITIC LIME and WETTABLE SULFUR to cast around the tree's root zone. This will help with infections, as well as condition the soil.

You might benefit from having your local extension service take a soil sample to find out, exactly, what is going on. This article will help you to find the closest one to you: https://www.gardeningknowhow.com/extension-search
