Asplenium australasicum is one of several popular and beautiful ferns grown as houseplants.
In return the Birds Nest Fern will give you lots of naturally glossy leaves arranged in a circular pattern which resemble a bird's nest (hence the common name for these houseplants).
These Ferns have very few problems. They're particularly good indoor plants for bathrooms or a frequently used kitchen because these places tend to have a steamy atmosphere.
POSITION Keep this evergreen in bright, indirect light and constant room temperature. It won't go dormant. With consistent care, it will grow year-round.
SOIL When choosing a potting mix, bear in mind the plant’s epiphyte habit, growing on other plants in its natural habitat, and choose a very loose, free- draining medium. Bark, grit and pumice or an orchid mix work well.
WATER Water thoroughly, then allow the top 2.5 cm of soil to dry out slightly before watering again.
Fronds that are yellow and wilted are a sign of overwatering. Cut back on water and trim off damaged fronds. Check the plant's roots to see if they have rotted - if they're mostly black, get rid of it. It's too far gone.
MAINTENANCE Repot in spring, when the roots have filled the pot. Move the fern to a pot that's only slightly larger. Use a pot with a drainage hole to prevent soggy soil.
Feed during the growing season at a low dosage. There is no need to feed during the winter at all, as these aren’t hungry plants and you could risk damage.
