Appearance
The fronds of Nephrolepidaceae are typically long and arching, with finely divided leaflets that give them a delicate, lacy appearance. The fronds may be bright green or have a bluish tint, depending on the species. Some species have fronds that are more upright or even pendant. The spores of Nephrolepidaceae are typically produced on the undersides of the fronds in structures called sori.
Care Guide
Nephrolepidaceae ferns are generally easy to care for and make great houseplants. Here are some tips for keeping them healthy:
- Water: Water your fern regularly, keeping the soil moist but not waterlogged. Avoid letting the soil dry out completely.
- Fertilization: Feed your fern with a balanced fertilizer every 2-3 months during the growing season.
- Soil: Use a well-draining potting mix that is rich in organic matter.
- Sunlight: Nephrolepidaceae ferns prefer bright, indirect light. Avoid direct sunlight, which can scorch the fronds.
- Hardiness Zones: Nephrolepidaceae ferns are generally not hardy outdoors and should be kept indoors in most climates.
Common Pests & Diseases
Nephrolepidaceae ferns are generally not prone to serious pest or disease problems, but they can be affected by a few common issues:
- Spider mites: These tiny pests can cause yellowing and webbing on the fronds. Treat with insecticidal soap or neem oil.
- Scale: These insects can cause yellowing and distortion of the fronds. Treat with insecticidal soap or neem oil.
- Brown spots: Brown spots on the fronds can be caused by overwatering, underwatering, or low humidity. Adjust your watering or mist the fronds to improve humidity.
Habitat
Nephrolepidaceae ferns are found in a wide range of habitats, from tropical rainforests to temperate woodlands. Some species are epiphytic, meaning they grow on other plants, while others are terrestrial, growing in soil. They can be found worldwide, but are most diverse in tropical regions.
