My Duranta has leaves that turn yellow and start rolling up. I have treated it for insects. Any suggestions?
It is in a container and a tree form.

Without seeing the damage, I can take a few guesses and offer insight as to what it could, possibly, be.
Usual suspects include overwatering, nutrient deficiencies of nitrogen, calcium, magnesium, or iron, depending on where the yellowing is occurring. Other problems could be pH issues, or infections.
Depending on the exact issue, you will either treat for fungal infection, or give it a boost of nutrients by adding an all purpose fertilizer. Restorative pruning may, also, be necessary.
