Hi everyone - hoping someone has some advice about my navel orange tree. I noticed some lesions in the bark and oozing sap at the bottom of the trunk. I don’t know how old the tree is, but it’s large-ish (about 12 feet wide and 8 feet tall) and looks healthy otherwise. It's growing well, the leaves are green and not falling off and there is a lot of new fruit on it. If there’s something amiss, I’m hoping that it’s early enough that I can do something to prevent damage. Thoughts on what it could be? Thanks in advance!
