Lemon tree

Question

My lemon tree is getting attacked by some insect. Some kind of glossy film and also beginnings of black specks on the leaves. What can I do? Is there something I can purchase or a home remedy?

Answer 1

The symptoms you see are probably caused by sooty mold and by aphids or scale insects that promote sooty mold growth. See these articles for control options:
