Fire Fern

Fire Fern prefers to be kept in a state of consistent, even moisture. Water the plant evenly every 3 to 4 days as water needs can vary from home to home. Aim to keep the soil damp but not soggy, and avoid over-watering, as this can cause root rot.

Fire Fern prefers bright, indirect sunlight and should be kept away from direct sunlight which can burn its delicate leaves. Consistent access to natural, filtered light, however is essential to keep its colors vibrant and healthy foliage growth. If the leaves begin to look washed out and stretched then it can be a sign of too much sunlight, in which case the plant must be moved to a cooler, shadier spot.

Fire Fern prefers warm temperatures of 70°F (21°C) or higher, and temperatures should not drop below 50°F (10°C). As it’s a tropical plant it does not like temperature fluctuations, so ensure to keep temperatures stable and consistent.

Fire Fern needs to be kept in quite humid environments and requires between 40%-60% humidity. If the air is too dry, mist the plant regularly as this can mitigate the need for a humidifier in small spaces. Regular and thorough misting around the foliage, especially in the evening, is essential.

Fire Fern needs a well-draining soil that holds some moisture but is also light in texture, such as a sphagnum peat moss based soil. It’s essential to avoid heavy, clay based soils as this can lead to root rot.

Fertilizing is important for keeping Fire Ferns in peak condition. Use a balanced fertiliser with a low nitrogen content and a higher middle numeral to ensure lush leafy growth. Fertilize twice a month during the autumn and spring, and once a month during the summer. Always fertilize less and more often rather than applying too much and not often enough.

Unfortunately Fire Fern is prone to pests such as scale, mealybug, and even spider mites if the humidity is not high enough. If any of these pests become an issue, insecticidal soap or neem oil can be used to get rid of them. If using either of these, it is best to spray in the morning and late evening when temperatures are cooler. Be sure to spray the entire plant, both on the leaflets below and leaves above, as the pests can hide in the center of the leaves or between the leaves and stem.

Repotting isn't strictly necessary every year as Fire Fern grows quite slowly, but should be carried out every few years to ensure the plant doesn’t become pot bound. The best time to do this is during the spring or summer, using new, sterile potting soil mixed with equal parts of compost.

Fire Fern doesn’t require much pruning, just occasional dead-heading and grooming when needed. If leaves become overly large they can be gently snipped off with sterile scissors to keep the plant looking neat and tidy. It’s important to avoid pruning back too much foliage as it restricts the growth potential of the plant.

Mulching may be necessary for Fire Ferns if planted outdoors. If grown indoors, however, mulching in-unnecessary. It’s best to use well stredded bark or coir chips for mulching outdoors, which should be applied at least twice a year in spring and summer.

Fire Fern can be propagated by laying the rhizome on top of a pot filled with moist sphagnum moss and then covering it with a thin layer of soil. This should be placed in an area with humidity and good light and is likely to be rooted within a few weeks. Once established, the root system can be divided through gently tugging the stems apart.

Support won't be necessary as Fire Fern does not climb and is not a trailing plant. However, if it does need to be supported due to its height or staking then moss covered sticks or wires can be used.

Fire Fern does not have a distinct rest period, however, it’s best to stop all fertilizing during the winter months. As long as light and temperature levels remain consistent, plants can grow in the winter.

Fire Fern is not toxic to pets.
