|My bush has leaves with brown spots turning yellow and dropping. What should I do?|
|It's normal for the oldest leaves, those near the center and lower down on the plant to turn yellow and fall off. They will be replaced by healthy new leaves. If the yellowing leaves are scattered within the plant, this is probably the cause.
Fungal diseases can also affect acuba leaves. If the yellowing and spotted leaves are the newer growth or the problem seems to be affecting most of the growth, a fungal disease is probably the cause. In this case you can prune to remove the affected leaves and stems and apply a fungicide such as Fertilome Liquid Systemic Fungicide. Best wishes with your acuba.
