Lighting Needs: Sharktooth ferns (Polystichum munitum) thrive in moderate to bright indirect light. Avoid direct sunlight, which can scorch their foliage.

Watering: Keep the soil consistently moist but not soggy. Water the fern when the top inch of the soil feels slightly dry, allowing excess water to drain from the pot.

Humidity: Maintain moderate humidity levels for optimal growth. Regular misting or using a humidity tray can help create a suitable environment.

Temperature: Sharktooth ferns prefer cooler temperatures between 50-70°F (10-21°C). Protect them from extreme heat and sudden temperature fluctuations.

Soil: Plant the fern in well-draining soil with good moisture retention. A mix of peat moss, perlite, and pine bark can provide the right balance.

Potting: Choose a pot with drainage holes that's slightly larger than the current root ball. Repot when the plant becomes root-bound, typically every 2-3 years.

Fertilization: Feed the fern with a balanced liquid fertilizer every 6-8 weeks during the growing season (spring to early fall).

Pruning: Trim away any yellow or brown fronds at the base to encourage new growth and maintain a neat appearance.

Pests: Keep an eye out for pests like scale insects or aphids. Regularly inspect the foliage, and if pests are present, treat with insecticidal soap or neem oil.

Propagation: Sharktooth ferns can be propagated through division. Separate the plant into smaller sections with roots and replant them in appropriate-sized containers.

Mulching: Apply a layer of organic mulch around the base of the plant to help retain soil moisture and provide nutrients.

Winter Care Reduce watering and fertilizer frequency during the winter months when the fern's growth slows down.

Air Circulation: Ensure some gentle air movement around the plant to prevent fungal issues. Avoid placing it in excessively stagnant or damp conditions.
