Why does it look black?
Alocasia black velvet is so attractively black because its leaves absorb light energy across the visible spectra. This means that they do not reflect any light. Besides, the veins of this plant reflect almost all of the visible spectra producing the black-on-white contrast of the leaves. Isn’t it interesting!
Even more interesting is that when you crush the leaf open, the typical green chlorophyll comes out.
How do differentiate between a healthy and diseased plant?

Causes and solutions to alocasia black velvet leaf curling
As a commonly grown indoor plant, Alocasia reginula ‘Black Velvet’ will comfortably grow in most household conditions. But problems can be faced while growing this little queen. Alocasia black velvet leaf curling is one of those. The probable causes of alocasia black velvet leaf curling and its remedy are discussed below:
Underwatering and overwatering stress
Alocasia plants are tropical plants and need plenty of moisture to survive. Proper watering and moisture regulation are vital parts of alocasia plant care routines.
If black velvet leaves are curling downwards, it could be due to underwatering or overwatering issues.
what to do?
Insert your index finger into the potting mix to determine the soil moisture level.
Water the plant and drain out excess water. Too much moisture will cause root rot, and the black velvet leaves will turn yellow in the long run.
Growing black velvet plants in containers will need fertilizer. Fertilization helps it to thrive and grow to its full potential. But black velvet plants are not heavy feeders like other houseplants. It would be best to play safe to avoid over-fertilization.
What to do?
It is recommended to fertilize the plant once or twice a month during the growing season. Black velvet usually goes dormant in winter and will not utilize the nutrients after fertilization.
Using a substrate with good drainage is important to prevent this plant from developing black velvet leaf curling. This plant is susceptible to root rot and does not like to sit in wet soil.
What to do?
The soil for black velvet should be coarse well-draining soil. Opting for a granular mix high in orchid bark and sand will help to provide the necessary drainage and root aeration, and you can supplement with additional perlite or vermiculite as necessary.
A mixture of these will create soil that will help to avoid any soggy or moist conditions.
Black velvet is a slow grower. So, you don’t need to repot too often. This could mean repotting the plant once every 1–3 years. But remember it will often reach a maximum size of 10-18 inches wide and tall; keep that in mind when considering what size pot to use for your little queen.
Temperature and humidity
If black velvet is exposed to cooler temperatures, it will go dormant until the temperature is increased.
The best temperature to maintain for the black velvet ranges between 59°F and 80°F.
The black velvet needs a humid environment (ideally 65% or more), and misting should not be the only way you provide humidity, placing a pebble tray nearby is a good way to increase the humidity around the plant consistently. The preferred levels for humidity are between 60%-75%.
Found on the jungle floors of its native countries, Alocasia black velvet loves to bask in the dappled sunlight that’s able to break through the canopy.
In the home, this means Alocasia black velvet will thrive in a bright spot with lots of indirect light.
North-facing windows are a good bet for guaranteed indirect light, but East-facing can work too as long as the morning sunlight isn’t too strong. It is possible to sustain lower light environments, but without enough light, it may go dormant.
Alocasia black velvet requires only minimal pruning, mostly through the removal of any dead or yellowing leaves. If you wish, you may choose to remove any of the lower leaves to maintain the shape or appearance that you prefer.
In addition, due to the texture of the leaves, it is necessary to check the leaves for dust and debris. Wipe off the leaves of your little queen with a damp cloth.
