Care Guide

Pteris ferns are relatively easy to care for, and they make great houseplants or additions to shaded outdoor gardens. Here are some care tips:

• Water: Keep the soil evenly moist, but not waterlogged. Water when the top inch of soil feels dry to the touch.
• Fertilization: Feed the plant monthly during the growing season with a balanced liquid fertilizer.
• Soil: Use a well-draining potting mix or soil that is rich in organic matter.
• Sunlight: Pteris ferns prefer bright, indirect light or partial shade. Avoid direct sunlight, as it can scorch the leaves.
• Hardiness Zones: Most Pteris ferns are not cold hardy and are best grown in USDA zones 9-11.

Common Pests & Diseases

Pteris ferns are generally resistant to pests and diseases, but they can still be affected by some common issues:

• Spider mites: These tiny pests can cause yellowing and wilting of the leaves. Treat with neem oil or insecticidal soap.
• Scale insects: These pests can cause yellowing and stunting of the plant. Treat with insecticidal soap or horticultural oil.
• Root rot: Overwatering or poorly-draining soil can lead to root rot, which can cause the plant to wilt and die. Avoid overwatering and make sure the soil has good drainage.
