PlantPalOrange or rusty spots on leaves
Look for tiny raised spots under the leaf that release orange or brown powder.
What to check first
Check whether the spots are raised and powdery. They may sit below lighter marks on top of the leaf. Flat brown marks or corky bumps without powder are less typical of rust.
What to do now
Pick up affected fallen leaves. If only a few leaves are badly affected, remove them while dry. Water at the base and give the leaves room to dry.
What to watch next
Check for fresh powdery spots on new leaves. If they keep appearing, find guidance for the plant species before deciding on treatment.
