The hardy but elegant Alocasia Regal Shield is widely growing from home to office and also garden. Besides simple care requirements, the fast-growing nature of this plant also helps a lot with bringing a fresh green look to your space.
This article will shed some light on this alocasia care, propagation, and tips for the best growth.
Alocasia Regal Shield, often called Alocasia Elephant Ear, is a cultivar originating from Africa. It has large foliages with heart-shaped and light veins on the deep green background and looks like the elephant’s ear.
The plant is grown for leaves, but some white or yellow long inflorescences may come on warm days. The mature Elephant Ear can reach 6 – 8 feet tall.
Would you like to grow your own Regal Shield? This video discusses watering, soil, and lighting conditions for Alocasia Regal Shields:
Alocasia Regal Shields thrive in rich, well-drained, and slightly acidic soil. For example, a potting mix includes peat and perlite for indoors and moist-retentive ground with active earthworms outdoors.
The ideal pH is around 5.5 – 7.0, and you can check it with a soil test kit. Then, adjust the pH by adding some sulfur to lower or lime to increase.
Alocasia care requires moist but not soggy soil. The plants may tolerate slight nonconsecutive drought, but it’s better to water them weekly or when the top 1-2 inches of the ground gets dry.
Do Elephant Ears like sun or shade? The answer is both but except for intense light sources. These plants love bright indirect sunlight.
For Alocasia care indoor, put them near a south or north-facing window and rotate the plant regularly since they tend to thrive toward the light direction.
Outdoors, grow them under large plants or a 40% shade cloth so that the plant can get some shade or filtered light.
As a tropical cultivar, Alocasia Regal Shields prefers consistent moisture with high humidity of up to 80%.
Alocasia Regal Shields thrive at a temperature around 68 – 86°F (20 – 30°C) for daytime and not lower than 60°F (16°C) for nighttime. The best condition is 77°F (25°C), while the weather under 60°F may make them turn dull and fall off leaves.
The significant reasons here are underwatering and low humidity. You should check the soil moisture regularly and maintain a hydrating routine.
The most common reason here is waterlogging, resulting in root rot. Identified by the roots are no longer white and firm but brown and slushy.
Now, check if you are overwatering or your pot is poor-drained. If excess water is slow-released, consider changing the soil or adding drainage material like activated charcoal to consume surplus water.
A significant cause for yellow leaves is salt buildup from over-fertilization. The solution is to water the ground 3 – 4 times deeply to wash off the salt.
Remember to drench the soil until the water drains out. Rainwater is the best way to go, but overnight freshwater is still sufficient to support the plant.
The best way to spread a rhizomatous plant is to divide its rhizome. Spring or early summer is ideal for distributing Alocasia Regal Shields, thanks to the great light and weather conditions.
- Gently dig the plant out of the ground or the pot.
- Separate the plant into parts so that there are roots and at least 1 – 2 shoots attached to each.
- Place the divided pieces into a moist potting mix, ideally an organic one such as peat and perlite with equal parts.
- Place the pot in a warm space and regularly moisten the soil with warm water.
- 2 – 3 weeks is enough for the plant to establish in the soil and generate new roots.
- 14 – 20 weeks is ideal for a baby plant to achieve full maturity.
Typically, you would need to repot the plant once every two years or more. It will take 2 – 4 weeks for the plant to return to normal growth.
There are 3 cues to change:
- The roots go out of the pot’s holes.
- The plant is so big that the container can’t hold it firmly anymore.
- The soil becomes poor-drained or low in nutrition after a long period.
Elephant Ear is a heavy feeder. Support the plant monthly with a water-soluble fertilizer with an N-P-K ratio at 20-20-20 or any homemade organic compost during spring and summer.
Alocasia is toxic for people and pets. So, keep it away from children and pets to avoid harming their mouth and digestive system from eating the plant.
Frequently Ask Questions (FAQ)
Can Regal Shield Alocasia take full sun?
If you want alocasia to be happy, find it shade! Alocasis are considered far more of an indoor plant than outdoor one, and can not grow well in full sun or hot locations.
They demand moist soil (even boggy soil) with lots of humidity to thrive (high humidity around the house is never a bad thing).
Is Alocasia Regal Shield poisonous?
Alocasia is a member of the Araceae or “Arum” family that are all are poisonous. They produce an irritant called calcium oxalate that can cause excruciating pain in the eyes, mouth, throat and stomach if ingested.
All parts of the plant including seeds, roots, leaves and flowers are toxic to humans so great care needs to be taken when handling Alocasia plants at home or in gardens with children or pets.
Does Alocasia purify air?
Air filtration plants are used to purify the air in hospitals, nurseries, and corridors.
Though Alocasia are not typically marketed as “air filtering plants,” they DO filter out high levels of pollutants from the air including toxins like CO2 which is linked to global warming.
They also produce oxygen making them user-friendly for people who suffer from asthma or other respiratory conditions that require clean constant oxygen flow.
