🌱 How to Care for Elkhorn Fern to Prevent Thrips?

💧 How to Water

Water by submerging the mount or misting the shield fronds thoroughly, then let the medium dry out almost completely before watering again, roughly every 7-10 days in warm months and less frequently in winter. Never let the plant sit in standing water.

☀️ Lighting

Place in bright, indirect light. A spot near an east- or west-facing window works well; avoid intense direct afternoon sun, which can scorch the fronds, but a little gentle morning sun is tolerated.

🪴 Ideal Soil

Skip regular potting soil. Mount on a wood or cork slab with a pad of sphagnum moss, or pot in a chunky, well-draining epiphyte mix (bark, perlite, coarse peat) that mimics its natural life on tree bark.
