Introduction

The Lemon Button Fern (a.ka. Nephrolepis cordifolia “Duffii”) is a beautiful, low-maintenance plant that is perfect for both indoor and outdoor spaces. It is a dwarf variety of the Boston fern and only grows to a maximum size of 12 inches tall. The fronds are small and round, and they range in color from bright green to yellow-green. The plant gets its name from the lemon scent it gives off during its active growth. The Lemon Button Fern is native to humid tropical regions of Asia, Australia, the West Indies, and Central America, so it thrives in warm, moist environments.

Light Needs

It grows under tree canopies in its natural habitats, so it does not need direct sunlight to thrive. However, it will grow best in medium bright, indirect light.

How Often to Water Lemon Button Fern

Like most ferns, do not let your plant dry out completely. Keep the soil moist but not soggy. The best way to do this is to water your plant when the top inch of soil feels dry to the touch. Be sure to empty any excess water from the saucer after watering so that the roots do not sit in the water.

Fertiliser

It’s is a slow grower and does not feed heavily. A light application of liquid fertiliser every 2-3 months during the growing season is sufficient. Be sure to follow the directions on the fertiliser package so that you do not overfeed your plant.

Soil

Lemon Button Fern prefer a loose, well-drained potting mix. It is said that they can do well in any type of soil until the soil is well-draining. You can make your own by mixing equal parts peat moss, sand, and perlite.

When To Repot Lemon Button Fern

They do not need to be repotted frequently. You can wait to repot your plant until it becomes rootbound in its pot. When you do repot, be sure to use a pot that is only 1-2 inches larger than the current pot.

Humidity

Lemon Button Ferns prefer high humidity, but they will tolerate lower humidity levels as well. If you live in a dry climate, you can increase the humidity around your plant by grouping it with other plants, running a humidifier, or setting the pot on a tray of pebbles and water.

Temperature

Lemon Button Ferns should be kept between 60-80°F (15-26°C).

How To Propagate Lemon Button Fern

Lemon Button Ferns are typically propagated by division. You can do this by carefully removing the plant from its pot and gently separating the root ball into two or more sections. Each section should have several healthy roots and at least one frond. Plant the divisions in individual pots filled with fresh potting mix and water them thoroughly.

Other Names

Nephrolepis cordifolia “Duffii”, Sword fern, Erect sword fern, Little-leaved sword fern, and Fishbone fern.
