Q.Yellow Scale on Hibiscus Leaves
I have washed the plant, showered it with water several times and sprayed with light detergent solution. The scale attacts the buds particularly, but also the leaves. My plant is a twined base and flowers beautifully when not attacted. I have tried chemical sprays and root granules to no avail. What can I do?

Try using neem oil. I have found that nothing works better than this for scale and aphids. Here is more information on it: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
