Crispy Wave Fern
Crispy Wave Fern (Asplenium nidus) is a popular houseplant with long, thin fronds of foliage that resemble a wave or curl. The fronds appear in light green hues, while the stalks are dark green. Crispy Wave Fern does well in humid environments and prefers some indirect or full shade. It is especially well-suited to living in terrariums or bottle gardens. Crispy Wave Ferns are popular for their ability to grow well in indirect and filtered light, which is often seen in modern apartments or offices. With proper care, this houseplant has the potential to be an attractive and low-maintenance addition to your home.
Crispy Wave Ferns should be watered thoroughly when the top inch of soil is dry to the touch. Allow the soil to dry out completely before re-watering. It is important not to over water, as this will cause root rot. Allow water to run through the pot and then discard any excess water that remains in the saucer.
Crispy Wave Ferns prefer either medium to low light levels, or bright, indirect, filtered light. Avoid placing your plant in direct sunlight, as this will damage it irreparably. The fern should not be placed too far away from a window either, as it may suffer from poor growth or long, leggy foliage if given too little light.
Crispy Wave Ferns prefer temperatures between 55–65°F (12–18°C). Avoid placing your fern in temperatures above 70°F (21°C) and ensure that any drafts are kept to a minimum.
Crispy Wave Ferns need high humidity. To increase the relative humidity around your plant, try grouping it with other houseplants or misting it weekly. Use a water spray bottle filled with room temperature water and lightly spray the leaves.
In terms of soil, Crispy Wave Ferns prefer a fast draining, organic potting mix. Commercial potting mixes designed for ferns or other moisture-loving plants are also suitable. A mix of 1/3 peat moss, 1/3 perlite, and 1/3 compost is also commonly used.
Crispy Wave Ferns should be fertilized once a month. Use a balanced all-purpose fertilizer diluted to half the recommended strength. Be careful not to over fertilize, as this can be detrimental to your plant's health.
Crispy Wave Ferns are prone to infestations from several pests, including aphids, mites, mealybugs, and thrips. Aphids are small and green or black and can be scattered throughout the foliage. Mealybugs are small, white, fuzzy bugs that leave a waxy deposit behind them. Mites are difficult to see, but will cause a webbing on the underside of the leaves. Thrips can leave dark spots on the leaves and are most likely to be found on the underside of the fronds. To address an infestation, first treat the plant with insecticidal soap, as this should take care of the problem. If the problem persists, it is best to discard the plant, as chemicals and further treatments may not be successful.
Crispy Wave Ferns should be in an organically rich potting mix for optimal growth. Depending on the size of your plant, you may want to do a full repotting every 2–3 years, replacing the old soil with new soil and a larger pot. If the plant needs repotting but is still contained in its current pot, you may want to top dress with fresh potting mix instead.
Crispy Wave Ferns should be pruned regularly to prevent them from getting overgrown. Use sharp, sterilized scissors or shears and cut away any yellowed, brown, or damaged fronds. You may also need to trim the longest fronds occasionally to encourage bushier foliage growth.
Mulching can be used to help keep the soil around your plant moist and cool in the heat of summer, and to help prevent the spread of any fungal diseases. Sphagnum moss, pine needles, or bark chips are all suitable mulches that can be used for this purpose.
Crispy Wave Ferns can be propagated by division or from cuttings. To propagate from cuttings, simply take a few cuttings from the plant and stick them in a pot filled with damp soil or moist sphagnum moss. The cuttings should take root within a few weeks. To propagate by division, carefully remove the plant from its pot and separate the rhizomes with a sharp knife. Replant in a separate pot and you have a new plant!
Crispy Wave Ferns can benefit from the addition of a moss stick or stake for support. Place the moss stick or stake in the pot and then carefully weave the fronds around it for support.
Crispy Wave Ferns are inactive in the winter months, with a rest period occurring between December and April. They should be given less water than they usually require during this time, but not neglected entirely, as they will still need some moisture. Fertilization should be stopped entirely during the resting period.
Crispy Wave Ferns are not toxic to pets or toddlers and can safely be kept in a home with children.
