Medium_lemon_tree lemon tree leaf has a lot of mold and the trunk has small rounded black spots like insects eggs

Answer: Hi Fa,
The lemon tree has been attacked by scale which will affect the health of the plant. These insects suck the sap from the plant and excrete a sugary substance. The sooty mould grows on the sugary substance and sometimes you will find ants on the plant as well. Apply some Pest oil onto the tree ensuring the scale are well covered. You may need a second application in 7-10 days. Fertilise the lemon with some Dynamic Lifter for Citrus and apply some Yates Uplift Organic Liquid Fertiliser to help improve the health of the plant.
