Taking Care of the Anthurium Crystallinum:

Before moving on to the in-depth discussion about the care of this beautiful and extraordinary plant. First, let’s talk about the crystallinum’s very basic care requirements:

Light Needs of the Plant:

Provide your Anthurium crystallinum with bright light, but it doesn’t hit it directly. This is because they love bright light, but they grow naturally in environments where they would still be receiving some shade. Direct light can destroy the foliage of your plant.

Watering the Plant Correctly:

Anthurium crystallinum should always remain moist. An important point for your information is that MOIST does not mean WET. Let’s understand this. Moist soil has a little humid wateriness, whereas wet soil has large amounts of water.

Anthurium crystallinum thrives in above-average humidity. It is best to replicate its natural environment of tropical rainforests, where it is always moist.

During the growing season, keep the top inch of the soil moist. Water the plant regularly, especially during summer. Never allow the soil mix or growing medium to dry out.

Talking about areas with humid weather, the plant can survive without water for up to two weeks. A secret for healthy plants is distilled water instead of tap water. Tap water has many minerals that can slow the growth of plants.

Temperature Requirements:

Moving onto the temperature requirements, this plant can grow well in normal household temperatures. But usually, it prefers warmer temperatures.

It thrives in a warm temperature range of 65-80 degrees Fahrenheit (18-26 degrees C). You should keep your plant above 55 degrees Fahrenheit at all times.

Keep your beautiful plant away from open windows and vents in winter. These plants can easily cope with changes. Somehow manage a constant temperature for your Anthurium.

For a quick recap, putting them in a warm area with humid air is best.

Soil or Potting Mix for the Anthurium Crystallinum:

As we all know, epiphytes need not be tightly packed into the soil. Instead, they need a well-draining, loose potting mix that holds some moisture.

Now, this might sound a bit anonymous! But the main thing is that the potting mix needs to keep some moisture and get rid of most of the water.

Anthurium Crystallinum

For making your own potting/soil mix, we recommend a soil mixture with one part perlite, one part coconut coir, one part sand, one part peat moss, one part pine bark, two parts orchid mix, and a few handfuls of compost.

This mixture will be quite airy and will keep your Anthurium roots to be able to breathe well.

Fertilizing the Plant Properly:

To fertilize this plant, a diluted liquid orchid fertilizer high in phosphorus is great. A basic slow-release or balanced houseplant fertilizer can work well too. Use the fertilizer monthly during the growing season (spring and summer).

Similarly, you can give your Anthurium some crushed organic matter about once a month to help with healthy and balanced growth. Again, this is copying its native environment because that’s how its epiphytic roots would receive nutrients in the rainforest. Plants can benefit from the addition of compost as a nutrient source.

Repotting of Anthurium Crystallinum:

The plant is a relatively slow grower, so you won’t need to repot it frequently. Instead, repot this plant when it becomes rootbound. Signs that a rootbound has occurred and you should consider repotting the plant include:

  • Roots coming out of the pot’s drainage holes
  • Testing if the roots are coiled around the bottom of the pot or the outside of the soil by taking the plant out of its pot.
  • Stunted growth and a general sad-looking plant

Use a pot with good drainage that is the next size up from the current pot when repotting. When possible, repot plants in the spring and summer when they are growing.


The crystallinum does not need proper pruning, but you should always keep checking and removing any dead or dying leaves.

Propagation of Anthurium Crystallinum:

The easiest way to propagate this plant is by simply dividing a plant growing in the same pot.

Slowly take the entire plant out of its pot and identify a piece with its root system. Make sure the piece has at least one leaf, but the more, the merrier.

Separate the root systems but be careful not to damage the roots. This can be done by hand, with a pair of clean, sharp scissors to cut the roots away from each other.

Set the new plants gently in appropriately sized pots. Never use big pots because they can lead to water clogging.

Water the plants and care for them how you normally would. A break would occur in growth, but soon they will grow normally.

The best recommendation is to do this during the growing season (spring and summer.

Anthurium Crystallinum Care in a Nutshell:

  • Give it bright but indirect light for long periods
  • Always keep it moist
  • Provide it with humidity and warm temperatures
  • It is best to use a loose, well-draining potting mix that retains some moisture
  • Use a balanced houseplant fertilizer, always in diluted form
  • Repot when growth slows down, or rootbound occurs
  • Remove any dead or dying leaves and clean, fresh leaves
