brown spots on birds nest fern Asplenium nidus 'Crispy Wave'

brown spots on birds nest fern Asplenium nidus 'Crispy Wave'The Bird's Nest Fern is an explosion of greenery wherever you keep it. It likes brighter light than the ferns that grow in the UK, since it's evolved in the South Pacific, but still should be kept out of direct sun. It is an epiphyte, so it grows onto trees or rocks rather than into soil; make sure its roots don't sit soggy and that plenty of air can get to them.

Scientific Name
Asplenium nidus (nest fern) 'Crispy Wave'

Common Name
Bird's Nest Fern, Pleated Bird's Nest Fern

Origin
Native to tropical Southeastern Asia, Eastern Australia, Hawaii, Polynesia, Christmas Island, India, and eastern Africa

Light
Likes bright, indirect light; a splash of direct sun in autumn and winter will help with its dormancy. Not suitable for low light where it is at higher risk of root rot.

Water
Allow the top third of the soil to dry out between waters; this will mean less frequent watering in less bright spots!

Humidity
Average humidity is fine for the Bird's Nest Fern; A humidity tray would be appreciated but misting can cause issues with the foliage. A hose down to clear it of dust every so often will be helpful as long as the leaves are able to dry out.

Soil
Use a well-draining soil mix, for example with added bark, to allow plenty of air to get to the epiphytic roots. Add bark or an Orchid blend to soil designed for Ferns for the perfect mix. Repot every few years in spring as the plant grows.

Food
Feed every four weeks with water in the growing season, reducing to every six in autumn and winter.

Temperature
Temperatures between 12-26°C are ideal for this plant. It can be brought outdoors in summer, but make sure it's in a shady spot, and watch for pests when bringing it back in!

Pet-safe
Yes, but too much nibbling won't be good for pets, small humans or the plant!

Sprouts Top Tips
Water into the soil directly to prevent extra water sitting on the leaf and causing issues. If the potting mix is drying out slowly, you can poke the soil with a chopstick or similar sized stick to allow more oxygen in and mimic the movement of insects.

Did you know?
Asplenium are epiphytes, so will grow in unusual places, including in walls and split stones!
