1. Sunlight and Location Requirement
Anthurium crystallinum is a tropical plant that grows under shades of large trees in its natural environment.
Therefore, while keeping them either indoors or outdoors, you need to maintain the same growing environment.
So what does it imply?
You will need to grow them in shades if you are growing them outdoors.
However, if you are growing them indoors, you will need to provide sufficient light and shades.
It is best to provide them with 10-12 hours of bright indirect light.
Along with that, it is better if you can provide them 2-3 hours of morning sun or afternoon shades.
Generally, the light requirements of Anthurium crystallium when grown indoors is about 70-85% sunlight. And, while growing outdoors, they need 20-40% of the outdoor’s light.
Symptoms of Insufficient Light
- Reduced photosynthesis and thus less plant energy production.
- Stunted growth
- Wilting and curling of leaves. Generally, it is the plant’s defense mechanism to save energy and reduce moisture loss.
- Drooping and falling of leaves.
- Hindrance in plant’s physiological function thus stressing the plant.
Symptoms of Extreme Exposure to Sunlight
- Browning of leaves edges
- Leaves turn crispy and dry
- Discoloration in leaves and flowers
- High rate of transpiration. It causes excessive water loss from the plant’s leaves, thus disturbing the plant’s moisture level.
Tips for Maintaining Adequate Light
- Introduce the plant to a brighter space. It is best to place your plant near an eastern-facing window as the plant can receive a few hours of morning light. However, you can place your plant near the eastern or southern-facing window (within 5 feet).
- Avoid shifting your plant from a brighter space to lower light space.
- Use a light and a slightly transparent curtain or drape to protect plants from the scorching sun.
- If your plant is not receiving sufficient sunlight, introduce them to artificial grow lights. Providing 8-12 hours of L.E.D. Lights are sufficient for Anthurium crystallium.
- As the intensity of natural lights is low in winter, it is better to give your plant a few hours of artificial light.
2. Watering Requirements
Anthurium crystallinum grows in the tropical rainforests under shades where the soil is generally damp and moist.
Therefore, you need to maintain the same moisture level in the soil as in their natural environment.
However, while doing so, you need to be careful that you do not waterlog the soil.
It is best to water your Anthurium crystallinum once a week in summer and twice or thrice in winter.
Anthurium crystallinum is an epiphyte bearing aerial roots that imbibe waters and oxygen present in the soil.
Hence, if you constantly go on watering them, it disturbs the plant’s natural physiological function.
You should always be cautious while watering them as they are prone to both underwatering and overwatering.
Symptoms of Watering Problem
Both overwatering and underwatering generally show similar symptoms. However, the difference can be identified if you pay close attention.
- If your leaves are entirely yellow with some brown patches, then your plant is experiencing prolonged drought.
- But, if the leaves are yellow at the edges and limp, it might be facing an overwatering problem.
- Generally, overwatered leaves are limp, soft, and mushy, while underwatered leaves are dry and crispy.
- Excessive watering might cause root rot, fungal growth, low soil aeration, and foul order in the soil.
- Similarly, underwatering causes curling, stunted growth, and wilting of leaves.
- Using too hot or cold water might stress your plant.
Tips to Maintain Adequate Watering
- Always water your plant thoroughly until the water does not run out of drainage holes. It helps to flush out extra salts present in the soil.
- Water your plants with either room temperature water or tepid water.
- You can also opt for a self-watering device by constantly checking the moisture level.
- Let the top 2-3 inches of the soil dry out in between waterings.
- You can check soil moisture by inserting your finger 2-3 inches deep in the soil or by using a soil moisture sensor.
- Empty the saucer soon after the water drains out of the pot.
- Avoid using water that contains excessive salts.
3. Favorable Temperature
As Anthurium crystallinum is a tropical plant, it adores slightly warm temperatures. However, they are not resistant to extremely high temperatures.
Therefore, it is essential to maintain an ideal temperature for their proper growth.
Extremely high or low temperature and constantly fluctuating temperature create hindrance in their growth.
Generally, the ideal temperature for Anthurium crystallinum is 65 to 75°F (18 to 24°C).
When the temperature goes beyond 80°F, it causes high moisture loss, low photosynthesis rate, and stunted growth.
Similarly, when the temperature falls below 55°F, the survival rate of your plant drops.
In harsh conditions, the cellular activities cease, the cell might burst and thus degenerate plants’ functioning.
Therefore, if you reside in the northern zones, you might need to bring the plant indoors during winter.
Tips to Maintain an Ideal Temperature
- Avoid keeping your plants near windows or doors during frosty winter nights.
- Cover the plants with a frost blanket or transparent blanket to protect them from cold.
- If the plant is smaller, you can keep the soil warm by using heating pads.
- You can provide insulation by covering the top layer of the soil with mulch such as straw and dried leaves.
- Avoid placing your plant in a sunny location during summer.
- You can balance out high temperatures by increasing humidity around the plant.
4. Ideal Humidity
Being a tropical plant, Anthurium crystallinum craves high humidity.
In their natural environment, they grow under shades where the water constantly evaporates.
Therefore, you need to recreate such an environment in your living space to grow them healthier.
Ideally, it is best to provide them with relative humidity above 70%.
Lack of humidity leads to curling, wilting, discoloration, and falling of leaves of your plant.
In addition, when the humidity is low in the environment, plants tend to lose their leaves, decreasing the surface area for transpiration.
The humidity indoors is about 40%. So, you will need to put on extra effort to maintain the ideal humidity for your Anthurium crystallinum.
Tips to Maintain an Ideal Humidity
- You can increase the humidity around the plant using a humidifier. By far, it is the most effective way of increasing humidity. However, it may be a higher side considering the budget.
- Next, you can use a wet pebbles tray under the pot. The water in the tray evaporates gradually, increasing humidity around the plant.
- Group your Anthurium crystallinum with other plants. It helps to increase humidity by natural perspiration. However, it also increases the chances of pests and diseases infestation.
- Next, you can mist the leaves every morning.
- Alternatively, you can place your plant in a humid part of your house like a well-lit bathroom.
5. Soil Type
The fundamental feature of Anthurium crystallinum is it is an epiphyte. Therefore, it grows on tree surfaces, on sides of hills, or any other moist surface.
Hence, its active environment does not demand a specific type of soil.
However, if you can provide them with the best soil, Why not? Why risk when you can easily maintain a good quality soil for them?
It is best to grow them in well-draining, porous, light, and nutrient soil rich in organic matter.
If the soil is poorly draining, it locks water in the soil. The water takes up the space of tiny air pockets present in the soil. As a result, the roots choke and suffocate.
Furthermore, the phenomenon seriously impacts the photosynthesis rate of the plant.
If you want to prepare the soil for your Anthurium crystallinum at home, follow the recipe below.
- Mix 1 part of potting Mix
- 1 part of peat moss or coconut coir
- 1/2 part of perlite or pumice
- 1/2 part of coarse sand
- 1/3 part of sphagnum moss
- And, 1/2 part of organic compost or worm casting increases microbial activities in the soil.
Pro Tip: You can use charcoal, wooden chips, pine barks, rice husk, etc. to make the potting mix light and porous.
Alternatively, you can buy a commercial potting mix that can be used directly. For this purpose, you can use,
- Miracle-Gro potting Mix
- Sun Bulb 5011 Better-Gro Phalaenopsis Mix
- Espoma AP8 8-Quart Organic Potting Mix
- Dr. Earth Pot of Gold All Purpose Potting Soil
Another thing to keep in mind about soil type is soil pH.
You need to maintain slightly acidic or neutral soil pH between the range of 6.0-7.0.
6. Adequate Fertilization
Proper fertilization is key to healthy and lush green plants.
Like any other plant, your Anthurium crystallinum too requires adequate fertilization for its proper growth.
Lack of fertilization in them causes several problems like stunted growth, limping, and drooping of leaves.
Also, nutrition deficiencies negatively impact the photosynthesis rate that might stress the plant.
Anthurium crystallinum is not a heavy feeder. Therefore, it is sufficient if you fertilize your Anthurium Crystallinum once a month in the growing season.
Generally, it is best to use organic fertilizers like worm casting, chicken litter, animal manure, etc.
Also, organic fertilizer helps in increasing the microbial activities in the soil and enhances the soil quality.
But, you can also use all-purpose liquid fertilizer or any other synthetic fertilizer like N.P.K. in a ratio of 5-5-5.
However, dilute the ratio to half as they are not heavy feeders.
Besides, overfertilization causes a high amount of accumulated salts in the soil, which causes the burning of foliage and stunted growth.
Here are some of the commercial fertilizers that you can use for your Anthurium crystallinum.
- Jobe’s Organics 09524 Purpose Granular Fertilizer
- Miracle-Gro Liquid All Purpose Plant Food
- Miracle-Gro Water Soluble All Purpose Plant Food
- Dr. Earth 71164 91164 1 lb 5-5-5 MINIS Life All-Purpose Fertilizer
7. Growth Habits
Are you worried because your Anthurium crystallinum is growing slow?
If so, relax your nerves. Generally, Anthurium crystallinum shows two different growth phases.
When the plant is young, it generally grows fast or at a moderate rate. But, once the plant matures, its growth rate is decreased.
A mature Crystal Anthurium grows about 50 cm every 2-5 years. It produces a new leaf only in a frequency of 3 to 4 weeks.
Since crystal Anthurium is a shrub, its growth is more lateral.
On average, Anthurium crystallinum gains a height of about 30-60 inches.
Similarly, its spread is about 18 inches when grown in an enclosed environment.
However, if it grows naturally in open space, its leaf can grow about 90 cm (60 inches).
8. Flowering Habits
Have you seen Anthurium crystallinum bloom?
Do not frown upon them if you did not know they do produce flowers. They produce flowers only when you provide them with the best care.
However, the flowers are not very attractive. They produce yellow-green or near-white flowers in clusters on the stem.
If grown properly, they can develop into peace lily-type spathes.
The flower blooms during spring and summer. You can increase the number of flowers by fertilizing them with phosphorous-rich fertilizer.
But, I suggest you not keep their flowers as they are not very attractive.
Plus, when the plant focuses on flower production, its energy is invested in flowers rather than on the foliage development.
Therefore, focus more on its foliage rather than flower production.
9. Pest Infestation
There is a brighter note when it comes to pest infestation in Anthurium crystallinum.
Generally, they are a resilient and robust plant that does not usually attract pests.
Still, they get infested with pests. And, I know as sad as it may sound, your plant might have caught pests.
But, hey, you can get rid of them, so do not get overwhelmed.
Here is a list of common pests and their symptoms in Anthurium crystallinum.
|Scale||1. Brown bumpy and white cottony lumps can be seen on the undersides of the leaves

- On incidence, the patches may spread to leaves, stems, and roots.
- Stunted growth
- Wilting, drooping, and falling off leaves
- Foul order might come from the soil
- Roots feel mushy and rotten
- In the case of bacterial blight, tiny water-soaked marks appear on the underside of leaves.
- Cut off the infected part immediately with sterilized pruning shears or scissors.
- Apply fungicides containing copper, mancozeb, or thiophanate methyl to control leaf spot diseases.
- In case of root rot, repot it as soon as possible. While repotting, use a well-draining pot with porous and fast-draining Potting Mix.
- Increase air circulation around plants and in soil.
- However, if the plant is severely attacked, you might not be able to save it.
- Avoid misting leaves at night. It increases the chances of fungal growth.
- Likewise, avoid misting water on buds and flowers.
- Keep your Anthurium crystallinum separate from other infected plants.
- You can spray the plant with fungicides once a year to avoid infestation.
- Loosen the top layer of the soil to prevent fungal growth in the soil.
- Avoid overwatering your plant.
11. Regular Pruning
Another important care factor for the proper growth of Anthurium crystallinum is regular pruning.
Generally, pruning helps to enhance new and healthy growth in the plants.
However, your Anthurium crystallinum does not require much pruning.
It is ideal for pruning them once in 1-2 years during fall or the end of the summer.
Here are a few tips to take care of while pruning your Anthurium crystallinum.
- Anthurium crystallinum is toxic. Therefore, I always say safety first. Put on gloves, goggles, and masks while pruning your plant.
- The plant does not require extreme pruning, cut off only dead, dried, discolored, and infected foliage and flowers.
- Avoid pruning more than 20% of the plant as it might stress the plant.
- Always use sterilized instruments for pruning. Also, ensure the instrument is sharp to lessen the chance of harming the plant.
- Choose a spot that is out of reach of children and pets while pruning.
- Also, throw the pruned parts immediately in the garbage bin to avoid contact with children and pets.
12. Potting and Repotting
Using the right pot is equally important as watering or fertilizing your plant. The type and size you choose affect the growth rate and health of the plant.
If you use a pot that is extremely small in size, it might choke your plant. Similarly, if you use a large pot, there are two plausible negative impacts.
The first is the plant gets sufficient space for root development. Thus, it will invest most of its energy in root development rather than shoot development.
Next is the soil in a larger pot that takes time to dry up. Thus, it might increase the chances of root rot and fungal growth in the soil.
The ideal pot size for your Anthurium crystallinum is 8-10 inches pot. However, you can use a 6 or 7 inches pot for a younger plant.
Besides the pot size, pot material also plays a vital role in shaping the plant. You can find a variety of materials in the market.
The material differs in terms of durability, aesthetic value, affordability, and accessibility.
You can choose any of the pots that you find convenient.
Here is a table with various pot materials, their Pros, and Cons.

Repotting Anthurium crystallinum
Anthurium crystallinum is a plant that adores being slightly root-bound. Therefore, you will not require to repot the plant more frequently.
Generally, you can repot your Anthurium crystallinum every two years. Similarly, the best time to repot it is during spring, when the plant grows rapidly.
Moreover, the plant exhibits stunted growth, yellowing of foliage, discoloration, and sluggish growth when repotting.
Next, you can know about its repotting requirement inspecting the drainage holes.
If the roots are severely tangled and poking out of the drainage holes, you might need to repot them.
Tips to Repot Anthurium crystallinum
- First thing first, you need to put on safety measures like goggles, masks, and gloves.
- Then, take the plant out of the pot gripping the base of the stem.
- Fetch a clean pot that is 2 inches wider and taller than the earlier pot. Ensure that the pot has good drainage holes.
- Now, layer the bottom of the new pot with pebbles.
- Then, almost half of the pot with well-draining Potting Mix. Insert the plant at the center of the pot, then fill it will soil from the sides.
- However, avoid filling it up to the brim. Instead, leave small space to add compost or fertilizers in the future.
- Then, water the plant thoroughly and place it in a bright area.
Whether you want more of Anthurium crystallinum or gift it to someone, propagation is the easiest way.
Moreover, propagating plants are cheap, effective, fun, and adventurous.
If so, why waste dollars buying the same plant from a nursery when you can produce one?
When you propagate Anthurium crystallinum by the asexual method, you can obtain genetically identical sisters plant. Isn’t it cool?
Generally, you can propagate crystal Anthurium by
- Root Division
- Stem cuttings
The best time to propagate your Anthurium crystallinum is in spring and summer, when the plant grows rapidly.
If you are ready, let us hop into the propagation method.
Propagating Anthurium crystallinum Via Root Division
It is the easiest and most successful method of propagation. It is because the plant already possesses a well-developed root and shoot system.
Now, let us begin with the steps.
Step 1: Moisten the soil of your Anthurium crystallinum a day before propagating it.
Step 2: Now, put on safety measures like goggles, masks, and gloves.
Loosen the top 25% of the soil. Then, take the plant out of the pot gripping the base of its stem.
Step 3: Untangle all the roots. Simultaneously, remove the soil from the plant.
Step 4: Now, look for sister plants or offsets. Once you find it, gently separate the baby plant from the mother plant. Here, you can use a sterilized knife or blade to cut the roots you find separating by hands difficult.
Step 5: Take a clean pot and layer its bottom with pebbles. Then, half fill the pot with soil, sphagnum moss, or LECA medium of your choice.
Step 6: And place the new plant at the center. Finally, fill the pot with the medium you are using.
Step 7: Water the plant thoroughly if propagating in soil and place it in a bright space.
If you are propagating the plant in water, take a clear jar and fill it with tap water. Then, place the plant and change the water once every 3-4 days.

Propagating Anthurium crystallinum Via Stem Cuttings
You can easily propagate Anthurium crystallinum by stem cuttings.
But, before that, you need to understand the basic feature of the plant.
Anthurium crystallinum is an epiphyte that has aerial roots. The point from where the aerial roots emerge is the plant’s node.
You can generally find the node at the base of the stem.
It is the very thing that you need while propagating your crystal Anthurium by stem cuttings.
To propagate your Anthurium crystallinum by stem cuttings, follow the steps below.
Step 1: Choose a stem that has vivid aerial nodes along with 1-2 leaves.
Check for pests and diseases infestation. If the part is healthy, then snip off it with sterilized pruning shears or blades.
Step 2: Make sure you are using a sharp instrument while taking cuttings. Cut the stem just an inch below the nodes.
Step 3: Now, the stem thus obtained is ready to be propagated.
At this point, you can apply rooting hormone to the cuttings. However, the step is optional.
Step 4: Now, propagate the stem either in soil or water medium.
If you are using soil propagation, make sure to bury the nodes in the soil. Whereas if you are propagating in water, dip the nodes into the water.
The cuttings will start producing roots in 2-4 weeks.
Pro Tip: Make the incision at a 45-degree angle to increase the surface area for rooting.
14. Toxicity of the Plant
Generally, all varieties of Anthurium are toxic, and so is crystal Anthurium.
The plant contains calcium oxalates, which cause harm to humans and pets when injected or in contact.
If the chemical enters the human body, it causes breathing difficulty, swollen lips and tongue, nausea, vomiting, and burning sensation in the stomach.
Likewise, it shows the signs of drooling, pawing at the mouth, and vomiting in pets.
Similarly, if one comes in contact with its sap, it can cause skin and eye irritation.
Thus, I advise you to keep the plant away from the reach of children and pets.
Also, you need to seek medical help if you or your children are exhibiting such symptoms.
For, pets you can consult a local veteran or Call the APCC at (888) 426-4435.
