Answer:
Hi Rosina, I really need a photo to diagnose your problem. Chinese Tallow Trees don’t usually get scale infestations – this is why the instructions say: “please try NOT to diagnose your problems yourself”. In my experience, these trees like a fertile soil and plenty of moisture. Perth has infertile soils that are very dry in Summer. So, water the tree once a week with a sprinkler for at least 25 minutes, and fertilise each Spring with Osmocote slow release granules. In case it actually is scale, spray the tree with Eco Oil in November. Don
