How often to water Staghorn fern
- Spring–Summer (Mar–Sep)
- Every 4 days
- When the moss or mix dries, soak the plant in a bucket for about ten minutes or water it heavily, as a guide; a mounted plant dries faster and needs shorter gaps.
- Autumn (Oct–Nov)
- Every 7 days
- As it cools the moss dries more slowly; generally water two to three days after it dries.
- Winter (Dec–Feb)
- Every 10 days
- Keep it on the dry side in winter, watering about four to five days after the moss dries, during a mild day.
Light and placement for Staghorn fern
A bright, airy spot is about right, from sheer-curtained light up to morning sun in spring and autumn; in shade the shield fronds stay small, and midsummer sun scorches.
Overwintering Staghorn fern
Overwintering guide: 5°C (41°F) or above
It takes down to about 5°C, but overwinter it at a bright window indoors on the dry side, avoiding cold water and direct heater airflow.
Fertilizing and repotting Staghorn fern
Fertilizer
Diluted liquid fertilizer about once or twice a month from May to September; a few slow-release pellets tucked behind the shield fronds are enough, and none in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Staghorn fern
- Left with dry moss, the antler fronds droop and die.
- Overwatering in winter rots the growing point.
- In too little light the shield fronds fail to develop and the plant weakens.
Tips for growing Staghorn fern
- Shield fronds turning brown is natural; leave them in place.
- The white fuzz on the fronds guards against drying, so do not rub it off.
- Mounting it on a board or cork with sphagnum moss shows it at its best.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
