Diseases in citrus trees manifest themselves in the form of fungi, bacteria, viruses, viroid, and mycoplasmas. The most deadly of the common citrus fruit tree diseases is Huanglongbing (HLB) previously known as greening disease that once infected, reduces the life expectancy of citrus trees to 5 years.


What are the black/yellow/brown spots on citrus leaves?

Citrus Greasy Spots are caused by an airborne fungus that establishes itself on wet decomposing fallen leaves. The fungus will then make its way into the tree with wind and rain. This causes leaves to have yellow spots with brown blisters that eventually create greasy black lesions.

Once you have removed the problem wood, you can trim it down to your desired shape and size. Try not to expose too much wood to the sun as lemons, like most citrus is susceptible to sunburn. In the case that you do expose too much of the trunk, you can always apply tree paint to protect your tree from sunburn.
