"Hello, I live in the northeast corner of Alabama and in early Feb., I pruned our muscadine vines. Two of the vines are still "bleeding" and forming an orange colored build-up. Should I do something? If so, what? Thank you for your time, D.L."
It's slime mold, a species of Fusarium. It grows in the sap. Looks bad but is harmless. When the sap stops running, the mold will dry and flake off.
That reminds me of another question I'm often asked about vines "bleeding". I'll deal with it in a separate post.
