Where should I place my Crispy Wave Fern?

Crispy wave fern comes from the tropical area. As They are from this area they love shaded low light. They prefer low light. Bright light can harm their leaves.

Place your Bird nest fern in some area where direct light couldn’t come. You can avoid the window if you want. Or you place them in a window then make sure a curtain gives a shade. The north-facing window will be pretty cool. Or you can set it in your bathroom. It will be a great place for crispy wave plants.

Bright light has an impact on the leaves. The leaves burn in bright light. The leaves turn yellow. Direct bright light gives you crinkle leaves. 

However crispy wave fern isn’t doing well in bright light. always ensure that bright light can’t receive them.

You can rotate them to get the light on every side when they are placed in the light. Then You find every side a beautiful shape.

They thrive on low light. In lower light they give you flatter leaves.

When I gave my fern low light I found a healthy bird nest fern. 

Sometimes I thought that the light was too low but I am surprised it is pretty well in such a condition. Don’t be worried if They are in low light. Just avoid the bright light.

Crispy Wave Fern Watering

As I mentioned before, their native is a tropical area. For this, they love moist soil. Moist means not wet soil. It likes dampness when you touch the soil. When you find the surface of the soil is dry then water it. You can check it by hand. Put your hand in the soil if you found the soil dry then water it. 

You can check it in another way. Take the pot in your hand. If you find it lighter than previous watering then water your plant.

In watering some terms should be taken under consideration.

The quantity of water depends on the environment, the size of your pot and plant. In growing seasons like summer and spring, they need much more water than winter. 

Water your Crispy wave plant once or twice a week. Don’t allow it to dry totally.               

Although it can tolerate dry soil. If it is going in repetition then it’s harmful Sometimes people forget to water for a couple of days. And make the mistake of giving too much water. Don’t do it. give the exact water and give it regularly. because over-watering causes root rot. 

 Water your bird nest plant in the morning. It gives enough time to absorb the water. Regular Night watering makes a brown spot in leaves. avoid night watering. 

Evening watering is not good for evaporation. 

 Give your plant the room Temperature water. Coldwater causes leaf drops. Coldwater gives them a shock. You can use distilled or filtered water. If you can’t afford this then take the tap water and leave it one day in your room. 

You can give the water from above. In this case, you can use this cute looking elephant-shaped watering can.

Take those kinds of pots that have holes. So that water can drain properly. People sometimes give water in the rosette center. It can’t drain the water.  

By Maintaining this process of watering you can find a healthy Crispy wave plant.

Which types of soil is best for Crispy Wave Fern?

The fern is epiphytic as we know. they grow in another tree. they don’t love normal potting soil. Avoid The normal potting mix always for Crispy fern.

The crispy Wave fern-root needs aeration. Chunky Potting mixture I mean coarse particles is pretty good. you can use perlite or Peat based potting mix. 

They love the soil being moist. Dry soil is not well for them. Birds nest fern prefers moist and well-draining soil. They face root rot problems. That’s why soil  should be well draining.

When you buy it, use the same soil with your perlite mix soil. In repotting you should be careful about your potting mix. Use the same quality of soil as you use before.

My plant is good in organic soil. First, I made a mistake using normal soil and found a very bad result. Use the best organic soil.

Make sure that your organic soil is clean because insects can be harmful to them. 

Temperature for Crispy Wave Fern

Asplenium Nidus is good at 18-23 degrees celsius. In Fahrenheit, it is (70-80 degrees). Indoor is the best place to locate them. This temperature will give you shiny beautiful leaves. under 55 degrees F (13 degrees C) and above 100 degrees F is deadly. In a warm environment, I mean high temperature the leaves turn yellow. Leaves are a dropout in this situation. 

The cool temperature also takes them under trouble. The leaves look brown in the cold.

They can’t bear the fluctuation of temperature. Don’t place them under the air conditioning. Avoid the place which is beside the heater.  

Too many Drafts and Warm areas must be avoided. Check the room temperature by a thermometer. And where you find the suitable temperature, place them. 

Crispy Wave Fern Humidity Criteria

For coming to the tropical area They prefer the higher humidity. especially in the winter, you should be more careful about the Humidity. 

In (60-90%) humidity the crispy wave plant thrives. as in the winter, You don’t give much water. You can increase the humidity in some simple way.

Firstly you can buy a humidifier. It will boost up the Humidity. and You shouldn’t worry about the humidity if a humidifier is in your room.

Secondly, You can place some plants together. make a small swarm with your plant. It will Increase Humidity.

Thirdly If you have not enough plants to make a community then use a pot with some water. And set the pot near to your plant. It is very helpful to raise humidity.

You can mist your plant leaves with water. In this case, you can use a spray bottle. But it sometimes may cause problems. To do this some people overwater their plant and it brings root rot problems.

Another cool idea I have used. I placed my plant in my bathroom and I don’t have to worry about humidity. It is very helpful for temperature fluctuation problems. This is helpful for the Light also.

In the bathroom, they are doing better than in bedroom.

Ensure the humidity for your Bird nest fern. lower humidity can cause death for your plant.

Crispy Wave Fern Fertilizer

Your beautiful crispy wave fern is not a greedy plant. You can feed them once a month. This month will be the growing season.

They don’t need fertilizer in the winter season. I mean from September to February. You can use normal liquid fertilizer. Liquid fertilizer is a good choice.

All-purpose plant food like miracle-gro you can use. You should dilute it to half strength and use it as a liquid fertilizer. 

avoid overfeeding, because overfeeding can burn the root. In spring if you use the fertilizer you will find healthy and beautiful birds nest fern. But not in the winter.

Crispy Wave Fern Propagation

Crispy wave plant propagation is not like other fern or plant. It can not propagate in a normal way. You can’t cut the leaves like other plants.

You should wait for their spores. It’s a long term process. It’s not so easy also. Here I will tell you the steps need to propagate fern from spores.

But if you are a houseplant enthusiast and wanna go deep into the propagation of Crispy wave fern from spores, I think you should watch the video below. This guy has over 5 years+ experiences on growing fern from spores.

Propagation Steps for Crispy Wave Fern from Spores

  • Collecting the spore
  • Collecting in the field
  • Sterilize the frond
  • Prepare the Growing Medium
  • Start with extra Water
  • Add boiling water after sometime
  • Sow the Spores
  • Put them in some light and Let them Grow
  • Patch out the Gametophytes
  • Patch again to turn the Gametophytes into Sporophytes

I think in mature leaves you can find the spore in the perfect environment. You will find some tiny sprout. 

Then collect the leaves and set them on a piece of paper. or you can use a paper bag. Some days later you can collect the spores. In another way when the spores are dropout from the fronds you can collect it. To grow them you need a moist medium.

Peat moss gives a good result for a moist medium. I use peat moss. It gives me such a cool result. A shady area is needed in propagation. You can take it under a glass or plastic and grow the spores. mist it daily.

When it is large then you can transfer it to a pot.

However, it is a very hard process. I failed at first then gradually I can manage it. 


when you find your plant root is too large then you should take it into another pot.  In repotting, always use the larger pot from the previous one.

As I mentioned before they are epiphytic plants so they love organic compost. When you repot it first ensure you take the larger pot than before. 

Take a pot that has a hole in the bottom.  

And take the organic soil. make sure they are clean. You can use some soil from the previous pot. After repotting observe and take care of it. 

Look whether it is set in its new home or not.

Common Pests Attack

Some people overwater their plant it Causes root rot as well as fungal problems. Check the soil so that water can’t make the pool. Using well drainage soil and a proper pot is a solution for this. 

In boosting up the Humidity you mist the leaves sometimes. Science misting may inspire fungal and Bacterial Infection. You can use other ways to increase Humidity.
