Anyone know what caused these spots on my staghorn fern and what I need to do to get rid of them?

This could be fungal (Rhizoctonia) or bacterial in nature. It appears that the lesions only affect a small amount of the frond, so that's a good thing. If it were my staghorn, I would use a sterile sharp knife and cut away the damaged lesion, extending the cut into healthy green tissue. I would then dab the cut borders with hydrogen peroxide and repeat the hydrogen peroxide application the following day. I would then sprinkle those cut-out areas with cinnamon. Be sure your staghorn gets bright indirect light and air movement. Also, you want that/those staghorns to dry out well before re-watering. Over-watering is the cause for most staghorn problems.

If this has only occurred on one frond, and the above treatment/change of conditions seems to have worked, leave the frond alone. IF the lesions form again, I would remove that frond. You don't want the rest of the plant to become infected.

Thanks for that advice! That is the only frond that has been infected so far. I'm going to take your suggestion and remove the lesions today when I get home.

Good luck with the staghorn, Kandace. I grow a lot of them. Do let me know how the plant does. You can get my "real" email address from my website.
