Black Velvet Alocasia are known for their velvety foliage and textured leaves.

This plant has a few specific care needs to know in order to keep your plant thriving and happy in your home.

  1. Water. Make sure to water your plant with distilled or reverse osmosis water since these plants are sensitive to the salts and minerals in tap water. Water your plant when the soil is dry to the touch.
  2. Light. Keep your plant in a spot getting bright indirect sunlight. This may be near a south, east, or west facing window or under plant grow lights.
  3. Fertilizer. Feed your plant with a natural or synthetic fertilizer during the active growing months from March through October.
  4. Humidity. Alocasias thrive in high humidity and would do best in a spot getting 60%+ humidity.

Alocasia Black Velvet thrive in bright indirect sunlight. Think of an area getting indirect sunlight, but never direct sunlight. Direct sunlight can scorch the delicate leaves of this plant.

A good spot for this plant would be near a south, east, or west facing window. If placing this plant near a window, make sure the window has a sheer curtain as you do not want to burn the foliage of this plant.

This plant can also be placed under plant grow lights as long as the plant grow lights aren’t too strong. I use T5 Barrina grow lights and they don’t burn any of my plants even though the plants are just a few inches away from the lights.


It’s important to water any Alocasia with distilled water or reverse osmosis water.

These plants do not like the salts, minerals, and chlorine from tap water. I feed my plants with the water from our reverse osmosis system which was under $200 on Amazon. You can also leave out tap water overnight and the water will be ready to use in the morning.

Give your plant water when the top two inches of soil are dry. This plant doesn’t like to fully dry out so make sure to keep a close eye on the moisture level. Check the plants soil moisture by using your index finger or a moisture meter.

Place your index finger about two inches deep to check the soils moisture level. You can do the same thing with a moisture meter.


Alocasia Black Velvet need well-draining soil in order to keep the plant thriving.

Since this plant likes to stay on the moist side, well-draining soil keeps good oxygen flow going through the roots. A simple soil recipe is 50% coco coir, 25% perlite, and 25% worm castings.

If you don’t want to make your own houseplant mixture, use a pre-made mixture like Fox Farm Ocean Forest that is made with a blend of earthworm castings, bat guano, sea-going fish & crab meal, forest humus, moss & more.


Black Velvet Alocasia do well in any home that is between the temperatures of 60 degrees F to 90 degrees (15 degrees Celsius to 32 degrees Celsius).


Alocasia’s need fertilizer to get the necessary nutrients to thrive in your home.

There are many types of fertilizer available and these include natural and synthetic fertilizer. If using a synthetic fertilizer, it’s important to dilute the recipe in half as synthetic fertilizers are often too strong and can hurt your plants.

I fertilizer all of my plants with a mixture of Liqui-Dirt and Dyna Gro. Every time I water my plants, they get a mixture of my favorite plant food and fertilizer. You can also use slow-release granule fertilizer which you sprinkle on top of your plants soil.

Fertilize during the active growing season which is typically March through October.


Alocasia Black Velvet need higher humidity to keep the beautiful velvety leaves healthy.

Humidity levels above 60%+ are ideal. If you don’t know what the humidity is in your home, get a hygrometer which can check the humidity wherever you place the plant.

To increase the humidity around your plant, I recommend doing the following.

  • Place plants together so they create a microclimate of higher humidity
  • Place your plant on a pebble tray with water so the water evaporates around your plant
  • Place your plant next to a humidifier so it gets the added humidity from the machine
  • Place your plant in a terrarium or greenhouse for consistent all day high humidity


Alocasia Black Velvet have a different propagation process than most plants.

To propagate this plant, you have to divide the growth into separate plants. Then you can replant the separate plants into your preferred substrate.

Many people put this plant in well-draining soil and even choose to grow the plant in leca.
