    Welcome to r/arborists! Help Us Help You: If you have questions about the health of your tree, please see our [Posting Guidelines](https://old.reddit.com/r/arborists/wiki/posting_guidance) wiki page for help with effective posting. **Please answer the questions listed there to the best of your ability.** ***Insufficient pics/info will will likely result in the removal of your post!!*** ([See rule 3](https://www.reddit.com/r/arborists/about/rules).)

    Visit the main wiki page for [Critical Planting/Care tips and Common Errors to Avoid](https://old.reddit.com/r/arborists/wiki/index); there’s sections on why planting depth/root flare exposure is so vital, along with sections on proper mulching, watering, pruning and more that I hope will be useful to you.

    If you’re posting about a tree ID (not permitted here; [see rule 1](https://www.reddit.com/r/arborists/about/rules)), see that wiki page for other subs and smartphone apps to try.

    Here is how you can arrange a [consult with a local ISA arborist in your area](http://www.treesaregood.org/findanarborist/findanarborist) (NOT a ‘tree company guy’ unless they’re ISA certified) or a [consulting arborist](https://www.asca-consultants.org/search/custom.asp?id=3818) for an on-site evaluation. A competent arborist should be happy to walk you through how to care for the trees on your property and answer any questions. If you’re in the U.S. or Canada, your Extension (or master gardener provincial program) may have a list of local recommended arborists on file. If you’re in the U.S., you should also consider searching for arborist associations under your state.

    If you are one of our regs and/or you work in the industry and do not want this message in your future posts, please pick an appropriate user flair (options available in the sub sidebar on PC, and on moble if using a browser).

    Hard to tell without more bark removal but this could be a man early white rot. Do you live in a particularly wet area where the soil doesn’t drain well?

    I’d stay away if you’re allergic to bees…

    It looks like a bacterial slime flux. I’ve had some efficacy in doing a systemic phosphonate fungicide bark treatment. Call an arborist that does treatments.
