Caring for a sword fern (Nephrolepis) in mineral substrate requires a few special steps to ensure the plant stays healthy and pretty. Here are a few tips:
-
Location: Place the sword fern in a bright spot, but without direct sunlight. A bright area with indirect light is perfect.
-
Temperature and humidity: Sword ferns thrive at temperatures between 18°C and 24°C. Maintain a relative humidity of at least 50% to keep the plant healthy. You can increase the humidity by placing a shallow bowl of water next to the plant or using a humidifier.
-
Watering: Water your sword fern regularly to keep the mineral substrate slightly moist, but avoid waterlogging. Make sure that no water remains in the saucer. If the substrate becomes too dry, the leaves can turn brown and die. A good trick is to pour about 1/3 of the amount of water over the substrate and put the rest in the water tank.
-
Fertilization: Fertilize your sword fern every 2-4 weeks during the growing season (spring and summer) with a half-diluted liquid houseplant fertilizer. There is no need to fertilize in winter.
-
Care and cleaning: Remove dead leaves and clean the fern regularly to improve ventilation and prevent mold growth.
-
Pests and diseases: Watch for signs of pests such as spider mites or aphids. If you spot any, isolate the plant and treat the pests with insecticides.
By following these tips, you can keep your sword fern healthy and beautiful in the mineral substrate. Remember that sword ferns are sensitive and it may take some time for the plant to get used to the new substrate. Patience and regular care are the key to success.
