Alocasia Regal Shield Care

The Alocasia Regal Shield is resistant to heat and drought, but it is very vulnerable to cold. This elephant ear plant is remarkably low-maintenance and simple to look after, so long as you can give it high humidity, healthy soil, and bright light.


A loamy, rich, acidic soil with good drainage is necessary for Alocasia Regal Shield because it is a heavy feeder. For this plant, a typical potting mixture with perlite additions will do. However, a mixture of perlite, fir bark, and coco coir in a 2:1 ratio would make a better growing medium. In order to add some extra nutrients, additional organic matter, such as compost or worm castings, may be added at a rate of about 10%. Every two to three years, the soil should be changed because this plant consumes a lot of food.


To support its growth throughout the growing season, the best Alocasia Regal Shield care will require routine feeding. This plant will benefit from a monthly feeding of a liquid fertilizer that has been balanced and dilute. To avoid chemical burn, make sure you adhere to all label instructions. During the winter, avoid feeding your Aloe. Mid-fall, feeding may be stopped.

This plant prefers a constant moisture level that isn't excessively wet. Before rewatering, let the top inch of soil dry out completely. Rainwater or distilled water are preferred because this plant is sensitive to chemicals in tap water. Wintertime watering needs to be cut back. Too much water will cause an Alocasia's leaves to droop. Alocasias that have been submerged will have wilting leaves.

Light Requirements

This plant prefers strong, indirect light that is up to 85%, like that coming from a west or east-facing window. Avoid placing your plant in the sun's direct path because the sun's scorching rays can seriously harm it. This plant's container should be turned frequently. By turning the container, you can maintain the plant's steady growth and gorgeous foliage as it quickly moves toward the light. If your Alocasia doesn't get enough light, its foliage will become dull.

Temperature & Humidity

Regal Shield Alocasia enjoys heat and humidity because it is a tropical plant. The ideal temperature range is between 68 and 77 degrees Fahrenheit, though it can withstand temperatures as high as 86 degrees. Never allow the temperature of your plant to drop below 60 degrees Fahrenheit as this could result in long-term damage. High relative humidity is ideal for Regal Shield's growth; it should never fall below 60%. It is advised to frequently mist the leaves or use a pebble tray or humidifier.


This plant can easily become top-heavy, so it's important to choose a heavy container for potting that has plenty of room for the roots to breathe. Choose a pot that is 1-2 inches bigger than the prior pot, and make sure it has enough drainage holes. Every two years, repotting should be performed.


Late winter to early spring is the ideal time to prune. Remove any diseased, discolored, or damaged leaves with sterile shears. Dusting can help maintain the luster of foliage.

Alocasia Regal Shield Propagation

Root division makes it simple to spread the Alocasia Regal Shield. This particular Alocasasia is known to have numerous offshoots growing from the mother plant, which may be divided and replanted into their own container. The best times to propagate plants are in the spring or summer when they are actively growing. Remove the mother plant's root ball and some soil before starting a new plant to propagate. After that, use your hands to gently separate some of the clumps. The clumps should then be planted in their own container, the soil should be refreshed, it should be thoroughly watered, and indirect light should be provided.

  • The best time to propagate is early spring, early in the growing season.
  • Propagation stresses out your plant in the same way that repotting does. So, only attempt propagation when you have a healthy and mature plant.
  • Don't propagate if you have a new plant or recently relocated it.

Propagation through Root (Clump) Division

  1. Water your plant and sterilize a knife blade with 70% isopropyl solution the day before you plan to propagate it.
  2. Unpot your Alocasia Regal Shield and flip your plant over. To see the rhizomes, roots, and petioles, gently tease out the soil with your fingers. Keep the roots intact at all costs.
  3. Slice through the rhizome with the sterilized blade to separate the pup from the mother plant. Make sure the pup that was separated has established roots and petioles.
  4. The pup needs to be repotted in moist potting soil. Select a pot with drainage holes that is large enough to accommodate the pup's roots and rhizome as well as its size.
  5. Place the mother plant's pot back in the ground.
  6. Maintain a warm, humid environment for both plants with lots of indirect light. If you have a humidifier, put it next to the plants and set the humidity level to 80%.
  7. Root development in the baby plant and the recovery of your mother plant will both take about 3–4 weeks. While this is happening, your plants might exhibit signs of stress.
  8. Your plants' recovery is evidenced by new growth!

Propagation by Offsets

  1. Use a clean cut with a sterilized knife to separate the mother plant from the offset by cutting at the base of the stem.
  2. Replant the offset in a potting soil that is evenly moist. In a few weeks, it will begin developing its own roots.
  3. Make sure to keep both plants in a warm, humid environment with plenty of indirect light. If you have a humidifier, put it close to the plants and set the humidity level to 80%.
  4. Both plants might exhibit some signs of stress, but they will get better in a few weeks.

Propagation by Bulb Harvesting (sometimes Called Corms)

Bulb harvesting is another method of propagating your Alocasia Regal Shield. The development of a new plant takes longer when it comes from a bulb, of course.

  1. Two days before propagation, water your plant.
  2. With care to prevent damaging its roots, remove your plant from its container.
  3. Take out any extra soil so you can look at the roots of your plant. Several bulbs are frequently hidden beneath the ground and entangled in the roots.
  4. When choosing mature bulbs, look for ones that are thick, round, hard, and easy to pull away from the roots. In an established plant, you should be able to find 5–10 mature bulbs.
  5. Separately, plant each bulb in a brand-new pot filled with new soil, root side down.
  6. Back into the original container, repot your mother plant.
  7. Water both plants.
  8. After being divided and replanted, you should anticipate that your mother plant will exhibit some signs of stress. Wait a few weeks and watch your mother plant heal.
  9. A successful propagation is indicated by new growth!
