Issue With Fruit On Lemon Tree

Question

Curious about what is covering the skin on my Meyer lemons. Tree and leaves look healthy and the inside of each lemon is unaffected. Thank you.

Answer 1

It could be melanose, a fungal disease. The interior fruit is usually unaffected, as you say. Here is more information and tips to keep it from returning. Also, the leaves in the background look chlorotic so I included information about that, too.
