When the plant is underwatering, it will cause curling leaves. Therefore, maintain the water requirement for this plant.

In an area with a good humidity level, the anthurium crystallinum can survive without water for around two weeks. However, when winter comes, it is advised to water the plant with lukewarm water.

Light Requirements

Place the anthurium crystallinum under bright light, but not direct sunlight. Direct sunlight will cause burning leaves. Generally, it requires 70-85% sunlight. In other words, you will need to provide consistent light exposure.

If you grow the plant outdoor, you can place the anthurium crystallinum under a tall tree where it will prevent the direct sunlight fall on its foliage. Here, light is very important to its growth. When it is placed under the shade, the plant will grow slower.


Due to its origin which is in tropical forest, the plant loves higher humidity. In its natural habitat, this plant gets so much evaporation of water.

When it comes to fertilization, organic fertilizer is the best choice. Your fertilizer should contain nitrogen, phosphorous as well as magnesium. Besides, the anthurium crystallinum responds well to liquid fertilizer.

Here we don’t suggest you chemical fertilizer due to the potential salt build-up. If you do this, it is suggested to flush the root.

For the best growth, choose a slow-release or organic fertilizer. The diluted fish emulsion once a month is also great to promote growth and keep the plant healthy.

  • Next plant each section into a different soil mix.
  • Provide the necessary nutrients and conditions such as humidity, temperature, lights, as well as fertilizer.
