Meyer Lemon Tree
I hope you can help me. I have a Meyer lemon tree in my yard, about 5 yrs old. They have big grey and white "stains" on the trunk and branches. They "LOOK LIKE" the coloring of swallowtail caterpillars. Also, the leaves don't look healthy. I have attached 3 pics. Please let me know what to do. Thank you, Carol

Unfortunately I am not able to see your pictures. Discoloration of tree trunks could be frost damage or dry root rot. The following articles discuss some diseases that can cause branch or trunk problems in citrus trees.
