Caring for a Staghorn Fern: Restringing and Understanding Spore Spots

A staghorn fern (Platycerium) owner asked if the plant needed restringing and whether black spots on fronds were a problem.

Black Spots Are Normal

The black dots are spores (reproductive structures), a sign of a healthy, mature plant. No treatment needed.

Restringing

Only restring if the fern feels loose on its plaque. The typical method:

1. Use the same gauge wire and screws.
2. Insert new screws into the wooden plaque.
3. Secure wire on one side, wrap around the root ball, fasten to the opposite screw, wrap back around, and secure to the first screw.

If you’re uncomfortable doing this, take the plant back to the shop where you bought it—they’ll usually restring for a small fee.
