How do you care for Staghorn Fern?
| Light | Bright dappled light or partial shade; avoid hot direct sun; very low light invites disease and pests |
|---|---|
| CO₂ | Likes some moisture but needs air movement; excess humidity causes black spot (no figure in sources) |
| Temperature | ≥ 5°C |
| Placement | NOT for a closed terrarium: it grows far too big (fertile fronds to about 90 cm) and needs air movement; sealed humid air promotes black spot. Open terrarium: only a young plant on a mount in a very large open vivarium/paludarium, and expect to move it out as it grows. Best mounted on a wall or board as a houseplant. |

Black patches and rot at the base from overwatering or humid stagnant air (black spot fungus); scale, mealybugs, aphids, spider mites. Brown felt under the fertile frond tips is normal spore patches, not disease.
How do you fix Staghorn Fern problems?
Mount on a board, bark or tree-fern slab over a pad of sphagnum, tied with plastic, nylon or non-copper wire.
