Alocasia reginula grows best under medium to bright, indirect light. Keep it away from direct sunlight as it can cause the leaves to be faded (bleached) and die. It also does well under a grow light where natural light is not adequate.
Too little light for Alocasia Black Velvet will signal dormancy to your plant which may cause the leaves to start dying in readiness for dormancy.
Regularly turn the pot to ensure that Little Queen gets light on all sides for even growth to prevent lop-sided growth. Check out this guide on understanding light for houseplants.
Water Alocasia reginula thoroughly and allow the top 2 in. of soil to dry out between waterings. Reduce watering during the cold season to keep the soil barely moist but never allow the soil to dry out completely.
Underwatering will signal dormancy to the plant which may cause the leaves to start dying in readiness for dormancy.
Alocasia Black Velvet does not like soggy soil as it is prone to fungal infestations like root-rot.
Therefore, ensure the pot has a drainage hole to prevent the soil from getting soggy. Read more on how to water houseplants.
Average warmth from 150C to 270C is ideal for Alocasia reginula. Below 150C, the plant may drop all its leaves and go into dormancy stage.
Alocasia Black Velvet also needs to be protected from draughts as it hates sudden changes in temperature. Check out this guide on understanding temperature for houseplants.
Alocasia reginula requires high humidity inorder to thrive. To raise humidity, set the pot on a wet pebble tray or use a cool mist humidifier.
Alocasia Black Velvet can also be grown in a bathroom or other moist areas in the home if the lighting is adequate. Check out these techniques on how to raise the humidity for houseplants.
Regularly clean the leaves by damp wiping them with a soft cloth to get rid of dust and discourage pests infestation.
Do not mist the leaves as the water droplets can spot the leaves. Read more on how to clean houseplants.
Feed Alocasia reginula with a balanced, liquid fertilizer every 4 weeks during the growing period. Withhold feeding during the cold season as the plant undergoes dormancy during this period and growth is minimal at this time.
Flush out accumulated salts arising from fertilizers every 2-3 months by running a stream of water through the soil until the water comes out through the drainage holes. Let the stream of water run for a few minutes. Repeat the process several times. Read more on how to feed houseplants.
Alocasia reginula prefers to be root-bound, therefore frequent repotting is not needed. Avoid frequent repotting as the plant can take long to recover from repotting shock. Repotting every 2-3 years should be adequate.
Repot into a 1 size larger pot during the growing season only if the roots have grown out through the drainage holes.
Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to fungal infestations.

Alocasia reginula (Alocasia Black Velvet) propagation can be done by plant division at the beginning of the growing season.
Carefully take out the Alocasia reginula from its pot and gently divide the rhizome into sections by cutting through with a sharp sterilized knife. Ensure that each section has 1-2 stems.
Plant the sections in individual pots in moist free-draining soil at the same depth that they were in the previous pot.
Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.
Place the set up in a warm, well-lit place and maintain the soil moist until new growth emerges after which routine care can begin.

There are three possible reasons why the leaves in Alocasia reginula are dropping and the plant is dying. These three reasons signal dormancy for Alocasia reginula and hence the leaves die in readiness to enter dormancy.
This happens during the cold season (winter) when the plant undergoes dormancy. Even if the foliage may die, the underground rhizome is still alive and can regrow under favorable conditions.
One possible reason why the leaves in Alocasia Black Velvet are dropping and the plant is dying is too little light.
Move the Little Queen to a brighter spot and ensure it receives medium to bright, indirect light or instal a grow light if the natural light is inadequate. Check out this guide on understanding light for houseplants.
