I live in Jacksonville, FL. A month ago I planted a Cassia tree (5 ft tall, 1. 5 inch diameter trunk). Nearly all the yellow flowers were gone. This week I noticed that some of the foliage is turning yellow. I watered daily for the first week and then twice a week. Lots of pine straw in the area cleared for the planting. I read, however, that the soil should not be too alkaline. I was under the impression pine needles are acidic. Mixed in a half cup of shrubbery food (16-4-8) with the compost at planting. Did I over fertilize?
It is possible that the roots were burned by the fertilizer when planted. The plant may also have an air pocket in the soil and the roots are drying out. Step firmly around the base of the plant to collapse any air pockets. I would also flood the area with water, meaning leave the hose running at a medium speed on it for 20-30 minutes. This will help wash out excess fertilizer and will also help further collapse any pockets in the soil.
I have a new cassia tree and need to know about planting it and its care.

I have a small golden splendor (cassia) tree that is approx 3 feet tall. It has split into 2 straight trunks about 8 inches from the ground. Should I cut off one of the trunks?
That is really up to you. It is more of an aesthetic choice than one for the health of the tree. You can remove one, if you don't want 2 trunks, but the tree will be fine too if you leave them both.
My tree looks droopy and the branches closest to the tree are looking bare. I'm not sure if the tree just needs food and, if so, what should I feed it? I do not see any bugs but is there a spray to keep it fungus and bug free?

Neem oil is both an organic insecticide and fungicide should either issue be affecting your cassia. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I planted my cassia tree last year. I trimmed it 3 months ago and it has a lot of dead leaves branches on it. It seems the new growth on it only stays green for about a week.

I have a cassia tree that is not doing well. It looks like it has red spots on the limbs and the lower branches are dead. The top is still blooming a little. Can you recommend what I can do about it?
It sounds like it has a fungus. Treat the plant with a fungicide, like neem oil, and this should help to clear it up.
Is my Cassia tree dead? The tree looks brown and is bare. I shaped it in autumn. If not, what should I do to make it look alive and produce the yellow flowers?
