Info
Nephrolepis undulata, also known as the Wavy Sword Fern or Undulated Boston Fern, is an attractive fern species native to tropical and subtropical regions. It is a popular houseplant and is also grown in gardens for its decorative and air-purifying qualities. The plant features long, arching fronds with undulating leaflets, giving it a unique and graceful appearance.
Plantation
-
Location: Choose a location with bright, indirect light. Avoid direct sunlight, as it may cause the fronds to scorch and turn brown.
-
Soil: Plant Nephrolepis undulata in a well-draining, peat-based potting mix with added compost or leaf mold.
-
Container: Select a pot with drainage holes to prevent root rot. The pot should be slightly larger than the root ball, allowing for growth.
-
Spacing: If planting multiple ferns in a garden, space them about 18-24 inches apart to give them room to grow and to promote proper air circulation.
Growing
-
Watering: Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of soil feels dry to the touch.
-
Temperature: Nephrolepis undulata prefers temperatures between 65-75°F (18-24°C) during the day and slightly cooler at night.
-
Humidity: Maintain high humidity levels around the plant by misting regularly or placing the pot on a tray filled with water and pebbles.
-
Fertilization: Feed the fern with a balanced, water-soluble fertilizer diluted to half strength every 4-6 weeks during the growing season (spring to summer).
Care
-
Pruning: Trim dead or damaged fronds regularly to maintain the plant's health and appearance.
-
Repotting: Repot the fern every 2-3 years, as it becomes root-bound, using a slightly larger pot and fresh potting mix.
-
Pest control: Inspect the plant regularly for signs of pests like spider mites, mealybugs, and scale insects. Treat any infestations with insecticidal soap or neem oil.
