Taking care of Colocasia Black Coral


The Colocasia Black Coral is quite fond of water. Therefore, the perfect technique to water your plant is to give the water every week, especially in the summer season. The amount of water should be sufficient to keep the soil moist until the next shift.

It can quickly take up the water through the roots when grown near a pond, river, or stream.

If the plant is not given the right amount of water, it can suffer drought. Therefore, it is also recommended that drainage holes are created in the pot to remove excess water retained at the bottom of the plant.


The plant needs moist soil to grow healthy. If the soil dries out, there is a chance that the plant will die.

For potting the plant indoors, it needs good drainage. It cannot survive in soggy soil; hence holes can be made to facilitate drainage. In addition, the soil should have air circulation and be nutritious for growing a healthy Colocasia Black Coral plant.


Colocasia Black Coral cannot grow through indirect exposure to sunlight. The ideal sunlight to meet the requirement of your plant would be bright but indirect sunlight. To be kept as a houseplant, it must be held in a place where it receives partial shade.

The plant shows its best colors when kept in the sun; however, keeping it in direct sunlight can scorch the leaves and make the plant lose its black color.


Colocasia Black Coral can survive well in warm temperatures if it is not kept in direct sunlight. However, very high temperatures can increase the chances of infectious attacks and diseases.


Humidity is significant for the growth of any plant, especially for plants that are grown in tropical areas. Therefore, we can say that Colocasia Black Coral needs high humidity.

In drier regions, it is suggested that you keep a humidifier to give the plant suitable humidity for developing healthy growth.


This Colocasia Black Coral loves to take nutrients; therefore, the soil should provide the plant with sufficient nutrition to grow properly.

However, fertilizers should be given in a moderate amount as too much of them can damage the plant.
