Alocasia Ninja

A Beginner's Guide to Alocasia Ninja Care | All you Need to Grow!

Alocasia Ninja

Family: Araceae
Common Name: African Mask, Elephant Ears
Botanical Name: Alocasia reginula ‘Ninja’

This overly confident Elephant Ear does not like to be confused with its close relative Black Velvet, as this particularly stealthy alocasia has earned its second stripe. If you look closely you can see that the Ninja has two pronounced white stripes along the leaf margins. Family squabbles aside, the Alocasia Ninja will produce slightly large leaves, but still remain small in stature.

Important! Alocasia are poisonous if ingested, so be very careful if you have pets and/or small children.

Light is critical for all plants, but especially for Alocasia reginula ‘Ninja’. Bright indirect light for about six hours a day is enough to keep these houseplants healthy. Alocasia can handle lower light or fewer hours of bright indirect light, but in order for the plant to really thrive it needs plenty of bright indirect light.


Alocasia has medium water requirements, which means they don't like to completely dry out, but they also don't like to sit in standing water. You want to let the soil dry out until 3/4 of the soil is dry. Alocasia reginula ‘Ninja’ doesn't like to be overwatered so if you are unsure about if it's necessary to water them, it's best to err on the side of caution and refrain from the rain head!

When you water these houseplants, saturate the soil and let the water run through the drainage holes in the pot. Well draining soil is very important for plants like alocasia. These houseplants simply do not tolerate wet feet.


Warmer temperatures are ideal for alocasia houseplants. These tropical plants prefer to stay between 60-80 degrees. Avoid drafts that can occur near windows and doors and also avoid placing the plants near heating or cooling vents.


The more humidity the better for Alocasia Ninja. These beautiful indoor plants thrive with high humidity, so placing the plant near a humidifier or using a pebble tray with water will provide the extra dampness they crave.


Proper nutrition will help your alocasia push out big, beautiful leaves. Fertilize when the plant is actively growing during the warmer months. Use a ¼ diluted complete liquid fertilizer when watering or you can use seaweed or fish emulsion. Alocasia needs their beauty rest and they require a dormant period. Do not fertilize during the colder months when the plant is not growing.

Pro Tips

  1. Routinely treat the plant and the soil with horticultural oil like neem oil. These houseplants are prone to pests, so taking preventative steps can keep the plant healthy and beautiful.
  2. Plants need clean leaves to effectively complete the process of photosynthesis. Gently clean the leaves using a damp cloth to not only keep the houseplant looking amazing but also to allow the alocasia to grow to its full potential.
  3. Don't be in a rush to re-pot. Alocasia likes to be slightly root-bound and prefers to stay in the same pot for a while. When you notice the roots beginning to poke through the holes in the grow pot or creep out at the top of the soil then it is time to re-pot.
