Air Plant vs Lace Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Air Plant
Tillandsia spp.
Air plants are epiphytes, meaning they grow without soil, absorbing moisture and nutrients from the air through specialized structures called trichomes on their leaves. They come in various shapes and sizes, from small, spiky varieties to larger, cascading forms. Their leaves can be silvery-green, gray, or even reddish. Air plants are popular for their unique growth habit and low-maintenance care, making them ideal for displaying in terrariums, hanging planters, or mounted on driftwood. They are primarily outdoor plants but can be grown indoors with proper care.
Lace Fern
Nephrolepis exaltata 'Bostoniensis'
The Lace Fern, a cultivar of the Boston Fern, is prized for its delicate, finely divided fronds that create a lacy appearance. It's an evergreen perennial fern, typically grown indoors as a houseplant, although it thrives outdoors in warm, humid climates. Its arching fronds bring a lush, tropical feel to any space. People grow it for its air-purifying qualities and its ability to add texture and visual interest to indoor environments. It is not naturally an indoor plant, but adapts well with proper care.

❓ Frequently Asked Questions — Comparing These Plants
Air Plant
What are the light requirements for Air Plant?
Air Plants need bright, indirect light to thrive. They can tolerate some direct morning or late afternoon sun, but avoid intense midday sun, which can burn their leaves. An east-facing window is often ideal. If your Air Plant is kept indoors, consider supplementing with a grow light, especially during the darker months. Signs of insufficient light include pale leaves and stunted growth. If the leaves turn reddish or brown, it could indicate too much direct sun. Place your Air Plant a few feet away from a sunny window or use a sheer curtain to filter the light. Proper lighting is crucial for photosynthesis and overall health.
How do I care for Air Plant?
Air Plants require bright, indirect light and good air circulation. Water them by soaking them in a bowl of water for 15-30 minutes every 1-2 weeks, depending on the humidity and temperature. After soaking, gently shake off any excess water and allow them to dry upside down to prevent rot. Mist your Air Plants in between soakings, especially in dry environments. Fertilize them sparingly with a bromeliad fertilizer diluted to half strength, adding it to the soaking water every month or two during the growing season. Avoid direct sunlight, which can scorch the leaves. Ensure good air circulation to prevent fungal growth. With proper care, your Air Plants will thrive and may even produce beautiful blooms. Regular observation is key to understanding your plant’s specific needs.
How do I propagate Air Plant?
Air Plants are primarily propagated by pups, which are offsets that grow from the base of the mother plant. Once a pup reaches about one-third the size of the mother plant, it can be carefully separated. Gently twist or cut the pup away from the mother plant, ensuring you don’t damage either plant. The pup can then be cared for as a separate plant, following the same care instructions as the mother plant. Propagation is best done during the growing season (spring and summer). Avoid separating pups that are too small, as they may not survive on their own. With proper care, the pups will grow into mature plants and eventually produce their own pups. This is a slow but rewarding process, allowing you to expand your Air Plant collection.
Lace Fern
What are the light requirements for Lace Fern?
Lace Ferns require bright, indirect light to thrive. Direct sunlight can burn their delicate fronds, causing them to turn brown and crispy. An east-facing window is often ideal, providing gentle morning sun. A north-facing window can also work, but be sure the fern receives sufficient ambient light. If your Lace Fern is placed in a location with less natural light, consider supplementing with a grow light. Avoid placing the fern near south- or west-facing windows without a sheer curtain to filter the harsh sunlight. Rotate the plant regularly to ensure even light exposure and prevent it from leaning towards the light source. Observe the fronds for signs of insufficient light, such as pale green color or leggy growth.
How do I care for Lace Fern?
Lace Ferns thrive in bright, indirect light. Avoid direct sunlight, which can scorch their delicate fronds. Water regularly, keeping the soil consistently moist but not waterlogged. Use well-draining potting mix to prevent root rot. Maintain high humidity levels by misting regularly, using a humidifier, or placing the fern on a pebble tray filled with water. Fertilize monthly during the growing season (spring and summer) with a diluted liquid fertilizer formulated for ferns. Repot annually in the spring to refresh the soil and provide room for growth. Prune away any dead or yellowing fronds to encourage new growth and maintain a tidy appearance. Protect from drafts and sudden temperature changes. Monitor for pests such as spider mites and scale, and treat promptly if detected.
How do I propagate Lace Fern?
Lace Ferns can be propagated by division or spores. For division, carefully separate the rhizomes during repotting, ensuring each division has healthy roots and fronds. Plant each division in its own pot with well-draining potting mix. For spore propagation, collect spores from mature fronds and sow them on a sterile potting mix. Cover with a plastic dome to maintain high humidity. Keep the mix consistently moist and provide bright, indirect light. Spores can take several weeks to germinate, and it will be several months before you have a plant large enough to pot up. Division is the much easier and faster method.
