How to Plant Bird’s Nest Fern
Planting a bird’s nest fern begins with choosing the right environment. These ferns are native to tropical rainforests, where they naturally grow on tree trunks as epiphytes.
-
Soil: Choose a light, airy mix that drains well but still holds some moisture. A combination of peat moss, perlite, and pieces of orchid bark creates the perfect growing medium for healthy roots.
Pot: Select a pot with good drainage holes. Clay or terracotta pots are ideal since they naturally absorb excess water, helping to keep the soil moisture balanced for the fern.
-
Position: Place the fern in bright, indirect light. Direct sunlight can scorch its delicate fronds.
Bird’s Nest Fern Care
Bird’s nest fern care is simpler than most indoor plants if you follow a few golden rules:
-
Light: Keep it in filtered or indirect sunlight. Too much shade causes slow growth, while direct sun burns leaves.
-
Watering: Always water the soil, not the central “nest,” as trapped water can cause rot. Keep soil evenly moist but not soggy.
-
Humidity: These ferns thrive in 60–80% humidity. Lightly spray the fronds from time to time, or place a humidifier nearby to maintain the damp air these ferns love.
-
Fertilizer: Feed monthly during the growing season with a diluted liquid fertilizer. Avoid overfeeding as it can burn roots.
Types of Bird’s Nest Fern
There are several varieties of bird’s nest fern and related hybrids, each with unique frond patterns:
-
Asplenium nidus – The classic species with smooth, wavy-edged fronds.
-
Asplenium austral gem – A hybrid with tougher, glossy fronds that tolerate lower humidity.
-
Crispy Wave Fern (Asplenium nidus ‘Crispy Wave’) – Recognized by its tightly ruffled fronds, excellent as an indoor air purifier.
-
Bird’s Nest Fern ‘Osaka’ – Characterized by narrow, curly fronds that create a dramatic display.
Pruning Bird’s Nest Fern
Unlike other ferns, pruning here is minimal. Simply:
-
Remove yellow or brown fronds at the base with clean scissors.
-
Never cut the central rosette (nest) as this is where new leaves grow.
Propagating Bird’s Nest Fern
Birds nest fern propagation is a bit tricky compared to other houseplants. They do not produce offsets like succulents. Propagation is usually done by spores:
-
When fully grown, bird’s nest ferns develop tiny spores along the undersides of their fronds, which serve as their natural way of reproducing.
-
Collect the spores and spread them on moist peat moss.
-
Keep in a warm, humid environment until tiny ferns appear.
Since this is slow, most gardeners prefer buying young plants instead of propagating at home.
Potting & Repotting
When it comes to potting a bird’s nest fern plant:
-
Move the plant into a slightly larger pot every couple of years to renew the soil and give the roots more space to expand.
-
Handle gently, as roots are delicate.
-
Choose a pot only one size larger to avoid overwatering risks.
