Growing Nephrolepis (Lemon Button Fern)

Known as the Lemon Button Fern, Nephrolepis cordifolia 'Duffii' prefers bright, indirect or filtered light indoors, evenly moist soil, and air that is not dry (see below for ways to increase humidity around your plant). Provide warm temperatures (60 ° F and above). Fertilize monthly in early spring and again in summer with a water-soluble fertilizer (20-20-20) mixed at ½ the recommended strength. Can summer outdoors in a shady spot.

Humidity: Most houseplants are native to tropical or subtropical regions of the world, where relative humidity is typically very high. They suffer in the dry air produced by furnaces and woodstoves. The best way to increase the humidity around your plants is to run a humidifier nearby. You can also set plants in trays filled with pebbles or gravel. Add water to a level just below the tops of the pebbles (if the potting mix in the pots comes in contact with the water, the mix will draw water into the pot, which will cause the mix to become saturated, eventually leading to rot). Refill trays frequently to replace water lost through evaporation. (Our Humiditrays perform the same function without the need for pebbles.)
