Houseplant of the Week: Lemon Button Fern

Posted on by

The Lemon Button Fern (Nephrolepis cordifolia ‘Duffii’) is a charming and compact variety of fern that has gained popularity among plant enthusiasts for its delicate appearance and easy care requirements. Its small, rounded fronds and fresh lemony scent (when brushed or crushed) make it a delightful addition to indoor gardens and terrariums. Here’s everything you need to know about this lush, vibrant plant:

Growing Your Lemon Button Fern!

Light – The Lemon Button Fern thrives in bright, indirect light. Direct sunlight can scorch its delicate fronds, while low light may slow its growth. A spot near an east- or north-facing window is ideal. If grown under artificial lighting, fluorescent or LED lights work well.

Watering – These ferns prefer consistently moist soil, but avoid waterlogging. Allow the top inch of soil to dry slightly between waterings. Overwatering can lead to root rot, while underwatering can cause fronds to turn brown and crispy.

Humidity – As a tropical plant, the Lemon Button Fern loves high humidity. If grown indoors, consider placing it in a bathroom, using a humidity tray, or misting it regularly. A humidity level of 50% or higher is ideal.

Temperature – The fern thrives in temperatures between 60-75°F (15-24°C). Avoid exposing it to drafts or extreme temperature changes.

Soil – Well-draining, rich soil is essential. A mix of potting soil with peat moss or coconut coir works well. Adding perlite or sand ensures proper drainage.

Fertilizer – Feed the fern with a diluted liquid fertilizer every 4-6 weeks during its growing season (spring and summer). Avoid fertilizing in the fall and winter when growth naturally slows.

Pruning and Maintenance – Remove yellowing or dead fronds to keep the plant healthy and encourage new growth. Its compact size requires little pruning overall.
