Hi Sally,

Hibiscus can be attacked by a number of sap sucking insects, such as aphids, mealybug, spider mite and whiteflies. It is likely what you are seeing is a substance called Sooty Mould. This is produced as a result of the insect sucking the sap from the plant. The first thing to do is to kill off the insect that is attacking the plant. We would suggest a product called PestOil . This product will suffocate the pest and at the same time help to lift off the Sooty Mould that is covering the leaf. To help the plant recover, apply an organic plant starter and root booster called Yates Dynamic Lifter Liquid Concentrate.
