Hello! This is my first post, hoping the knowledgeable people here can help me out . We've been living in this house for about a year and a half (Tampa Bay area in FL), and have a gorgeous big orange tree in the yard. Shortly after we moved in we had a smaller one next to it removed because it was dead (I forget what the arborist said had happened, but it was a rot or fungus common in the citrus trees in this area right now.) I've been worried ever since that our lovely big tree contracted the rot from the smaller one, and I've been keeping an eye on it for symptoms. So, with that in mind, I have a few questions (see pictures for reference):
1) Is the new branch that sprouted a good thing or a sucker that needs to be removed? Included close ups of its leaves and the ones on the main tree for comparison.
2) Is the fungus at the base benign or an issue?
3) Is the big patch of bark peeling a problem or normal?
Thanks so much for any insights! I'd do a lot to keep this great tree alive .
