Answer: Your Australian Sword Fern is one of the most adaptable of all ferns grown indoors. It likes heat and humidity, and moist soil so don't let it dry out again. It also thrives on a constant source of nutrients so try feeding your plant with a half-strength dilution of liquid fertilizer every 2-3 weeks. It's normal for the oldest fronds to die off. As long as you have new growth emerging from the center of the plant, your sword fern is healthy. Prune away the dead fronds to make room for healthy new ones; if the air is dry (as is often the case during winter indoors), mist your plant everyday. When the weather warms, take it outside and hose it off periodically, both to discourage spider mites and to remove any dust from the fronds. I think once you regularly increase the humidity around your fern it will grow lush and thick and lovely. Enjoy!
