Care Guide

There are several main keys you should pay attention to when caring for the plant. The alocasia bisma is a plant that is sensitive to light changes, watering habits, humidity levels, and also temperature. To keep the plant thriving, make sure you mimic its natural habitat.


Water Requirements

Alocasia bisma enjoys moisture. You can water the plant every two weeks as well as mist it. However, be careful with the watering habit, you should not overwater it. The plant indeed loves moist soil, but not wet one.

To help you decide the right time of watering the plant, check if the 2-3 inches of the top soil is dry. Besides, let the water dry out first in between watering to prevent the plant from root rot.

On the contrary, this plant cannot withstand dryness. It will cause the edges to go brown.

Light Requirements

Place the alocasia bisma in a medium to a bright place. But you should not place the plant under direct sunlight because it will scorch the foliage. You also should not place the plant in a shady area as it will slow down its growth. Consider using the grow light to boost plant growth.


Alocasia bisma is a plant that loves high-humidity areas. If your house cannot provide this condition, you can create it. You can buy a humidifier or create a pebble tray. And another way to increase the humidity level is by creating a mini biome in which the plant can share humidity. You can group the plant.

However, you should remember, when grouping the plant, make sure each of them is free from pests and diseases.


Aim for a temperature between 18-25ºC. Avoid drafty areas and a place near the heating system.

Fertilization is required to help the plant thrive. General-purpose fertilization will do just fine, and you don’t have to give the plant booster because it will damage the plant.


The best thing about the plant is you don’t need regular pruning. If it is needed, you will only need to prune the plant to remove the damaged part or prevent it from diseases.

If you want to prune the plant, use clean pruning shears.


Repotting is required when you see the roots start to root bound. Or, you see the roots start growing out of the drainage holes.

In choosing the new pot, you must pick the one that has one size bigger than the current one. Don’t choose a pot that is way too bigger because it will possibly submerge the plant with water that later can lead to root rot.


Propagation can be done by using the stem method. Follow these steps:

  • Cut the healthy stem of the alocasia bisma
  • Prepare a soil mix in a pot with a depth of around 20-30 cm. You have to make sure the pot has drainage holes.
  • You can use the compost soil mix in this case.
  • Next, plant the stem of alocasia bisma but just half of the stem.
  • After you have finished planting the alocasia bisma, place it in a bright area but not under direct sunlight.
  • Make sure the soil is moist and check its condition often. If you find it dry, water it soon.


The alocasia bisma is not meant to be eaten. The plant is toxic to both people and animals. Place the plant away from children’s and pets’ reach.

Pest and Diseases

Pay attention to pests and diseases if you want your plant to thrive. The alocasia bisma is susceptible to spider mites, whiteflies, mealybugs, earwigs, cutworms, thrips, and leafminers.

Some indications tell your baby is sick, such as:

  • Stunted grow because of a lack of nutrients
  • The leaves look paler which indicates nutrient deficiency
  • Spotted leaves that indicate spider mites damage
  • Curling leaves that indicate a lack of watering
  • Soft spots and roots that indicate root rots because of excessive water

Diagnosing alocasia disease can be very confusing. But you can start with the cultural conditions. If you know it is not the problem, then the chances are your plant is infected with bacterial problems and fungal infections.
