This dirt like thing is on much of my Skip Laurel. It’s a mold right? Can you help identify the mold, cause and remedy?

  • Can you check beneath the leaves to see if there's anything there that shouldn't be - also the woody stems. You're looking for shield shaped objects on the stems, or fluffy white deposits under the leaves, or even small insects under the leaves.

    It looks like sooty mould, or sooty mould previously formed and dried out a bit - sooty mould is associated with heavy aphid or scale infestation. Does the black mould wash off if you try, or is it actually in the leaf?

Sooty mold is exactly what it is. Confirmed by someone who saw it live.
