The nephrolepis cordifolia, which is also called the lemon button fern or fishbone fern, is a hardy houseplant that is easy to take care of and great for people who are new to gardening. This fern is a great addition to any indoor plant collection because of its small size and lush green leaves. Discover how to take good care of your nephrolepis cordifolia by reading on.
Overview of the Nephrolepis Cordifolia
The nephrolepis cordifolia is a small type of the well-known Boston fern. It comes from Asia and has gracefully arching leaves that smell like lemons when they are crushed. In general, these ferns get about 12 inches tall and 12 inches wide.
Some key traits of the nephrolepis cordifolia:
- Thrives in medium to bright, indirect light
- Prefers warm, humid conditions
- Grows best in acidic, moist soil that drains well
- Low maintenance and quite hardy
- Propagates easily by division of the rhizomes
- Non-toxic to pets
Providing the Right Growing Conditions
The nephrolepis cordifolia is not too picky, though, and can handle a variety of conditions in the home. So, making sure your fern has the best conditions will help it grow.
Light
This fern does best in bright, indirect sunlight. An east or west-facing window is ideal, as it will receive gentle morning or afternoon sun. Direct sun will scorch the delicate fronds, so be sure to keep the fern shaded at all times. It can also tolerate low light, though growth may slow.
Temperature & Humidity
Warm temperatures between 60-80°F are preferred along with moderate to high humidity. The humidity levels found in bathrooms or kitchens will suffice. You can also place the pot on a pebble tray or use a small humidifier nearby.
Soil
Well-draining, acidic soil is best. Aim for a mix that retains moisture but never becomes waterlogged. Standard commercial potting mixes work well.
Water
Keep the soil consistently moist, taking care not to overwater. If the plant gets too dry, the fronds will turn brown and crack. Water the plants well until water drips out of the holes in the ground, then let the top inch or two of soil dry out before you water them again.
Fertilizer
Apply a diluted liquid fertilizer every 2-3 months during spring and summer. Ferns are light feeders, so don’t overdo it.
Displaying Your Nephrolepis Cordifolia
The lush, graceful fronds of this fern make it a perfect tabletop or desktop plant. Place it among other low-light plants or allow it to stand alone as a focal point. The lemon button fern also looks fantastic in hanging baskets, where the arching fronds can trail over the sides.
Pruning and Maintenance
Fortunately, this plant requires very little pruning or maintenance. Remove any dead or damaged fronds at the base to encourage new growth. Dividing overcrowded plants every few years will stimulate growth and allow you to propagate new ferns.
Propagating Your Lemon Button Fern
Propagating nephrolepis cordifolia from division is quite simple. Carefully remove the entire plant from its pot and gently tease apart the root ball, dividing it into smaller sections while keeping as many roots intact as possible. Re-pot each new division in its own container using fresh potting mix. Water well and place in bright, indirect light.
Common Concerns
This hardy fern will thrive with basic care, but may experience a few issues if conditions are not ideal:
- Dry, brown fronds – Increase watering frequency and humidity
- Wilting fronds – May indicate either too much sun or overwatering
- Yellowing fronds – Usually a sign of too much sunlight
- Crispy fronds – More humidity needed
- Few new fronds – More fertilizer may be required
Fortunately, these problems are easily remedied by adjusting care. Your nephrolepis cordifolia will reward you for years to come if provided with the proper growing environment. It’s an excellent choice for beginning gardeners and makes a lush, graceful addition to any indoor plant collection.
