Q.Cassia Tree Leaves Turning Yellow W/ Spots

Zone 32950 | allisonsunny added on March 26, 2020 | Answered

My 1 year old cassia tree has leaves turning yellow with tiny brown spots. Brown spots are also on some of the green healthy leaves. Does anybody know what this is and what is going on? I don’t wanna lose this tree and I actually have 2. Is not enough water or is it a disease.

That is a bacterial or fungal blight. Common this time of year, but with some perseverance and time, you can get rid of it.

Your first line of defense will be to clean up any debris around the tree. Then trim off as much of the affected growth as possible. Treat with a fungicide/bactericide, and apply DOLOMITIC LIME and WETTABLE SULFUR, according to all packaging instructions, to the soil around the tree.

This should suffice for treatment, but you may need to do it for a few seasons until it is cleared.
