Humidity Tolerance

Despite being a tropical plant, Alocasia Red Secret can tolerate low humidity. It can grow in a house where the humidity levels are not as high as 80%. But low humidity levels will affect the freshness of its foliage. It will not have such shiny leaves in low humidity.

Dormancy

This beautiful species goes dormant as soon as winter hits. Low light and low temperature are its key signals to enter its resting phase. As soon as your Alocasia plant enters its dormancy period, move it to a warmer spot. Do not overwater or fertilize it during these days.

Alocasia Cuprea Care

Alocasia Cuprea care involves three times watering per week and two times fertilization per month. It prefers well-draining soil with a pH of 5.0-8.0. The temperature required is 10-29°C. It needs bright, indirect sunlight. It prefers 80-95% humidity in its surroundings. Its growth zones are 11 and above.

Water Requirements

This gorgeous Alocasia needs average watering. It has similar needs to any average houseplant. You need to water it two to three times every week. Never over-water your plant. Overwatering makes the plant susceptible to root rot. With root rot, your plant cannot survive for long. Underwatering is also never a choice.

The easy way to check if your plant needs watering is to stick your finger in the soil to 1-2 inches. If you feel damp or moist soil, do not water. If your finger comes out dry, water your plant right away. Always pour lukewarm water into your plant’s pot.

Soil Requirements

Alocasia Cuprea needs well-draining, organic soil to thrive. Well-draining soil does not allow water to stand; this prevents the plant from getting root rot. This plant can grow in a wide range of pH, from slightly acidic to slightly basic. The pH can range from 5.0 to 8.0.

You do not need to buy a special potting mix for this plant. You can make a potting mix on your own at home. A mixture of coir fiber and perlite suits well for this plant. Coir fiber resembles the properties of sphagnum moss, but it contains more nutrients (it is a good thing here). Perlite increases more aeration, so it lets the soil breathe.

Sunlight

Alocasia Cuprea needs indirect sunlight to remain fresh and shiny. Its leaves need the correct light exposure to maintain their beautiful colors. You can place this plant in an east or north-facing window. In both these spots, this plant receives bright, indirect light, which is sufficient for its proper growth.

If the plant does not get enough light exposure or is made to sit in bright sunlight for too long, its leaves turn yellow. The leaves start to lose chlorophyll. This can kill your Alocasia plant. This is why plant placement is really important.

Temperature Requirements

Alocasia Cuprea is a tropical plant that can survive the climate of tropical and subtropical regions. The ideal temperature range for its optimal growth is 10-29°C. At night, it can survive temperatures as low as 12°C and as high as 18°C. It is the normal household temperature. You can easily grow it inside your home. It won’t bother you much for any temperature regulation. But if you grow this plant outdoors, you will have to be a lot careful about temperature fluctuations. In winters, move its pot indoors to prevent it from getting any cold injury.

Humidity

Alocasia Red Secret loves to live in areas with high humidity. Its natural habitat offers it high moisture, so you will have to do the same inside your home. It needs 80% to 95% humidity in its surrounding air. This moisture level is a lot higher than the normal household humidity. This is why you should increase the humidity through several simple tricks. You can place your plant over a pebble tray. For this, take a tray and fill it with pebbles. Then fill the tray with water; water should never be at a lesser level than the pebbles. Place the plant on top of the tray. As water will evaporate from the pebbles, it will all go to the plant’s foliage. It will do the trick and increase the humidity for this plant.

Fertilizer

This beautiful Alocasia plant is a heavy feeder. It needs to be fertilized often to thrive and flourish. Fertilizing the plant will provide it with all the essential micronutrients that are necessary for the lush growth of its foliage. You should add fertilizer to this plant’s soil after every two weeks.

You can use liquid fertilizer or regular all-purpose fertilizer. Make sure to dilute the fertilizer to half of its strength before adding it to the plant. Never fertilize this plant in winters. Winter fertilization will build up salts in its soil and will kill the plant eventually.

Grooming and Pruning

Brown leaves, yellow stems, and damaged roots need to be pruned. At the beginning of each growing season, take out your gardening shears, disinfect them, and prune the damaged foliage of this Alocasia; this plant will benefit from it. Disinfecting the shears is important so that the plant is not exposed to any infection. Yearly pruning does not only groom the overall appearance of the plant but also makes room for new growth. Never prune your plant in winters. This is because, during those days, the plant is in its resting stage. Pruning will further slow down its growth.

Re-potting

This beautiful plant needs to be re-potted after every two years. When the plant is root bound, it needs a new home. Every two years, when you see outgrowth in the draining hole of this plant, prepare a new pot for it. Always use a pot that is one size bigger than the original one. This must be done in the growing season, which is spring.

Propagation

Propagation of Alocasia Cuprea can be done through root division and in water. These two processes may sound difficult, but they are not. Let’s learn the easy steps to carry out these processes.

Through Root Division

  • Take a separate pot and half-fill it with potting mix.
  • Now take out the healthy Alocasia Cuprea from its pot.
  • Shake off excess soil.
  • You will notice some clumps of roots on it. These are the baby offsets.
  • Use a sharp blade or knife to cut some of those clumps. Never forget to sterilize the knife beforehand.
  • Place the baby offsets into the new pot and fill it with more potting mix.
  • Water the pot and place it in a well-lit spot.
  • In just some days, you will see a baby Alocasia growing out of the soil.

Water Propagation

  • The process for getting baby offsets is the same as above.
  • Once you get the clumps, take a bowl and fill it with water.
  • Do not fill it to the brim.
  • Clean the clumps, remove any soil, and place them into the bowl of water.
  • Make sure the roots are under the water.
  • Change the water after 10 days.
  • Once new roots start to grow and reach 4 inches, move the clumps to a new pot.
  • The pot must have a good potting mix.
  • Place the pot in a bright spot, and watch the plant grow into a young, beautiful Alocasia.
