Crispy Wave Fern Care

This epiphytic tropical plant will thrive if kept in a warm, humid environment. It will require consistently moist soil and very high humidity to proliferate. 

Crispy Wave Fern Soil

The Crispy Wave Fern will grow best in a mixture of organic compost, pine bark, and perlite. Alternatively, you may utilize a commercial cacti/succulent mix. 

Crispy Wave Fern Fertilizer

The Crispy Wave Fern will not require much fertilization. However, it will benefit from a monthly feeding during the warm growing season of spring and summer. Utilize a diluted, balanced fertilizer indicated for houseplants. Do not feed your plant in winter. 

Crispy Wave Fern Watering

As a plant accustomed to the tropical rainforest, the Crispy Wave Fern will prefer to be kept evenly moist at all times. Therefore, the soil of your crispy wave fern should be kept moist but not oversaturated with water or soggy. Additionally, this plant is sensitive to cold or overly warm water and will prefer room-temperature water. The crispy wave fern is also sensitive to chemicals in tap water. Therefore, it is best to water your crispy wave fern with rainwater, distilled, or filtered water. 

Crispy Wave Fern Light Requirements

The Crispy Wave Fern will prefer to be grown in filtered indirect light. Placing your crispy wave fern next to a northern-facing window will be perfect. Ensure that you do not expose your plant to direct sunlight, as this causes foliage to scorch and burn from too intense of direct sunlight. 

Crispy Wave Fern Temperature & Humidity

Being a tropical plant, your crispy wave fern will like to remain consistently warm. You should strive to keep your Crispy Wave Fern between 60-72 degrees Fahrenheit and never above 100 degrees Fahrenheit or below 55 degrees Fahrenheit. Additionally, this plant is sensitive to quick fluctuations in temperature. Therefore, keep your plant away from drafts, AC units, heaters, and cold windows. Your crispy wave fern will prefer to be kept in high humidity, between 60-90 percent. You will likely need to increase your home’s humidity to keep this plant happy. Consider investing in a humidifier to reach the ideal humidity.

Repotting Crispy Wave Fern

The Crispy Wave Fern will only need to be repotted as soon as it visibly is too large for its container and is toppling over. Select a container that is 2-3 inches larger than the previous container. Repot your plant, refresh the soil, tamp lightly, water thoroughly, and place it in indirect light. You may opt to choose a larger pot if you would like your crispy wave fern to grow larger quicker. Alternatively, you may decide to keep your plant in a small container and refresh the soil, and trim down some of the roots to keep it compact in size. However, this plant will not grow well if it does not have ample humidity no matter the container size it is provided.

Crispy Wave Fern Maintenance & Pruning

You will only need to prune your Crispy Wave Fern for aesthetic purposes. Periodically remove any discolored, dead, or diseased foliage using sharp, clean shears. If you notice foliage with brown spots or foliage that is rotting at the base, you may have an overwatering problem.

Crispy Wave Fern Propagation

This Fern is not easy to propagate, and propagation is often left to professionals. The Crispy Wave Fern may not be propagated by root division or stem/leaf cuttings.

To propagate your Fern, it will need to be done either through tissue culture or spores. You may collect spores of your Crispy Wave Fern by leaving a mature leaf on a paper plate for a few days. This leaf should have visible clusters of spores on the underside of the leaf. After the leaf has dried, collect the spores from the plate and sprinkle them on moist peat moss. Keep the peat moss moist in a shaded area and mist frequently to encourage sprouting. After the sprouts have become a couple of inches tall, replant them into their own individual containers. Keep in mind that propagation through spores is quite difficult and can rarely be successfully completed by inexperienced gardeners. However, the end result is worth the trouble if you are able to propagate your Crispy Wave Fern successfully.
