Fern: Lemon Button
In their native environment, lemon button ferns grow as understory plants and are accustomed to indirect light conditions. When grown indoors, they grow best in medium, indirect light but can also tolerate low light or bright light conditions. However, never place your lemon button fern in direct sun as it will burn the delicate leaves.
Lemon button ferns thrive in acidic soil that is moist, loamy, and well-draining. That being said, these ferns are highly adaptable and can do well in a variety of soil conditions. For the most part, a standard houseplant soil is perfect for these little ferns.
As with most ferns, the lemon button fern should never be allowed to fully dry out. Water your fern at least once a week to ensure that the soil stays consistently moist. While these ferns appreciate consistent moisture, never waterlog the soil as it can lead to root rot.
Temperature and Humidity
These ferns prefer warm, humid conditions. For the most part, typical household temperature and humidity levels should be fine for lemon button ferns, although if your house is particularly dry your fern will appreciate some added moisture. Try placing your lemon button fern near a small humidifier or in a high-humidity room like the bathroom or kitchen.
Ferns are generally light feeders and the lemon button fern is no exception. Apply a balanced fertilizer diluted to half strength every few months during the growing season.
Due to their compact size, lemon button ferns do not require any aggressive pruning to keep them happy and healthy. However, it is normal for some fronds to die off throughout the year—especially in the fall and winter months—and removing these dead fronds will help to keep the plant tidy and make space for new ones. Use a sharp pair of scissors or pruning shears to remove browning or dead fronds by making clean cuts near the base of each frond.
