Regal Shield Alocasia Care Guide
watering requirements


Alocasia Regal Shield requires moderate water and performs best when the top few inches of soil are dry. The frequency of water depends on the environment, but the soak and dry methods are ideal for all Alocasias. This method helps reduce the risk of root rot. You can test through your finger whether your plant needs water or not. If the soil is dry one inch down, it’s time to water it. 

A constant moist soil is idyllic for Alocasia Regal Shields’s growth. We recommend watering the plant every three days in summers and reducing the water frequency in winters to once a week to ensure its vigorous growth. Keeping balance while watering the plant is imperative, as overwatering may cause root rot. Overwatering has serious repercussions as the plant foliage starts to get yellow, and root rot can eventually result in the plant’s death. When you notice sudden wilting or drooping of leaves, it’s a sign of under-watering. 

As for as the water for Alocasia Regal Shields is concerned, rainwater or distilled water is perfect for its growth. Pour the water slowly and evenly around the corners of the container until it begins to ooze from drainage holes. 

sunlight requirement

Light Requirements:

The plant is happiest indoors, getting bright and indirect light from the south or north-facing windows. Please place it in the sunniest window of your home but make sure that direct sunlight does not hit the leaves, or else they will start to scorch, which is irreversible. Likewise, rotate the Alocasia Regal Shield weekly as the plant grows towards the light. 

Keep your Regal Shield Alocasia in bright shades for outdoor light as it can withstand a bit of sun. It would be perfect to place it in some covered area outdoors where it’s mainly in the shade but receives dapple light. Direct morning and early evening sun is also suitable for its growth. When you keep the plant in these conditions, it will do wonders.

humidity and temperature

Humidity and Temperature Requirements:

Elephant ear plants do wonders in tropical conditions and grow well in hot and humid environments. These plants do super well outdoors during spring and summers when the humidity is about 70%. For indoors, it’s always better to keep a humidifier or pebble tray near the Alocasia Regal Shield for its profligate growth and health. In case of a lack of humidity, the plant might get attacked by spider mites.

As for the temperature, the Alocasia Regal Shield performs well in 70-to-80-degree Fahrenheit outdoors; it also does well at 90 degrees. However, you would have to keep an eye on the soil as it might dry faster in hotter temperatures. Please do not keep the plant under 65-degree Fahrenheit as it won’t survive. When the indoor temperature drops in winter, the elephant ear might go dormant, and for that cause, you would have to water it less. 

soil requirement

Soil Requirements:

Alocasia Regal Shield requires acidic soil for its healthy growth. The perfect PH level of potting soil should be between 5.5 and 7.0. This PH level effectively holds all essential nutrients for plant growth, and to maintain the soil acidity, you can either add a layer of peat moss or spray diluted vinegar on the soil. For making a vinegar solution, you will need to add two drops of vinegar to a gallon of water. 

Moreover, potting soil of Regal Shield Alocasia should be well drained and well aerated to prevent root rot and other fungal diseases. Root rot is a complicated disease that can damage your plant ultimately. The soil should be able to retain moisture for the plant’s roots. Wet or musky soil isn’t good for Regal Shield as it has very bad aeration. 

Alternatively, you can prepare a soil mix to keep your plant healthy. For making the soil mix, Take one part of peat moss, one part of Perlite, and one part of Potting soil

Peat moss helps to keep the roots hydrated as it has excellent moisture retaining properties, while Perlite allows the water to drain quickly and preserves the soil well aerated.



Alocasia Regal Shield doesn’t need repotting for at least two years. The plant stays healthy in the same container for several years until it signals you. If you observe that the roots are growing out of a drainage hole, the pot is now small for the plant, and it needs a new home. 

Repotting is a simple process, and it should be done with care. Repotting must be done in the growing season because when the plant is moved to a new container, it remains in transplant shock for many days, but when you transfer the Regal Shield in spring or early summer, it comes out of shock quickly. 

We recommend using a new potting mix and fertilizers with every report as it will restock and recommence all used nutrients and minerals. 



We can define propagation as the multiplication of plants. Different methods are used to propagate a plant. Two methods are most viable to propagate the Alocasia Regal Shield; corms and plantlets. 

Plantlets Method

The plantlets are produced at the base of a plant. 

  • With the help of a disinfected knife, separate these little plantlets. 
  • Now, plant them into a little damp potting mix of one part peat moss and one part perlite. You can use sphagnum moss for growth.
  • New roots will start to sprout out from plantlets in one week. 
  • Watering during this time is very important. All you need to do is to properly water the plant and place it in a warm area.

Corm Propagation Method

  • Grab a container and fill it with a fresh potting mix or moist sphagnum moss.
  • Then, take the main plant from its pot and shake off its excessive soil. 
  • Tease the tangled roots with your fingers. While teasing the tangled roots, you will notice that some roots are forming corms. 
  • Take a disinfected knife, cut those corms, and plant them into the new container.
  • The corm should be partly submerged and partly exposed to the air in the pot. You can also cover the pot with plastic wrap to create a warm and humid effect or simply use a pot with humidity dome.
  • The most important part is to keep the soil moist and place the pot in a bright and warm spot. 
  • Within 4 weeks, the corms will root and a new leaf may appear.

Corm propagation method of Alocasia Regal Shield


The Elephant ear plant is a heavy feeder that requires monthly feeding. Most of the nutrients from the soil are used up as the plant ages. If you don’t apply fertilizer, your plant will stop growing and won’t be bearing any new leaves and buds. That’s why fertilizing the plant is important to encourage growth. 

To increase the organic content of potting soil, you must add some balanced animal dung, compost, or organic manure for nutrient rich soil. Otherwise, you can also use slow-release or diluted liquid fertilizer if you are short of time. But make sure to water the plant before adding any fertilizer. 

maintenance and cleaning


When it comes to maintenance of the Alocasia Regal Shield, it requires cleaning and pruning only. Cleaning is compulsory for plant growth. Regular cleaning and pruning will ensure the health of the Alocasia Regal Shield. Pruning dry and damaged leaves will maintain their energetic look. The ideal time for trimming is late winter and early spring.

The plant starts active growth at this time of year, so it is recommended to prune it during late winters and early spring. The appropriate way of pruning the leaves of the Alocasia Regal Shield is to slender them from the base. Dead, yellow, and old foliage must be trimmed away to boost growth. 



Like all other Alocasia plants, the Alocasia Regal Shield is also toxic to pets and humans. It would help if you keep your children and pets away from this plant; it contains calcium oxalate crystals, which can irritate lips, tongue, mouth, and throat. In rare cases, nausea, vomiting, and diarrhea have been reported after ingestion.

Generally, the symptoms develop quickly and may last for half a day.  It’s recommended to protect yourself while working with this plant.

Pests Diseases & Common Problems


Alocasia Regal Shield is a lovely plant, but it’s also not safe from pests. The most frequent pests that can infest your attractive plant are aphids. Along with aphids, mealybugs and spider mites may also attack your plant. 

It could be a severe problem for the plant, and you should start treating it as soon as you notice it. You can rub the leaves with a bacterial soap or neem oil to eliminate the pests. Spraying is also a good option, and you can spray a strong stream of water on the leaves to knock the pests off from the leaves.

Common Diseases

It’s essential to learn about the common diseases that Regal Shield may have so that you can address the problem immediately and prevent it from reoccurring. The most common diseases Regal Shield does have are;

Powdery Mildew

This disease produces a powdery white fungus on the Regal Shield’s flowers, leaves, and stems. It’s caused by lack of water and poor ventilation. To prevent this disease, make sure to water your plant correctly and if it’s already infected, ensure to get rid of affected areas. You can also use fungicide in serious cases. 

Bacterial Leaf Spot

If your Regal Shield plant leaves turn brown or have black edged lesions and release some fluid, your plant is likely affected by bacterial leaf spot disease. This disease can’t be fixed; the only cure is to clip the affected leaves and keep them dry for a few days. 

Leaf Edema

The discolored patches on the leaves of Alocasia Regal Shield mean that your plant is suffering from leaf edema. Leaf edema is caused by excessive watering. In that case, trim the affected leaves and shift the plant to aerated soil. 

Root Rot

Root rot is the most common disease in the Alocasia family. The root rot may cause the plant to wilt, leaves will become yellow and drop, and roots will turn brown. Root rot may kill your plant, and the way to save it is by reviewing your watering frequency and repotting the plant while cutting away the infected roots during the process. You may apply a fungicide to the soil to be safer. 

Common Problems

If you properly water your Alocasia Regal Shield and provide adequate sunlight, you can save it from many problems. But if the water and sunlight are not effectively provided, your plant may face some problems. 

Excessive watering may cause yellowing of leaves. To address this issue, water the plant appropriately and keep it in proper sunlight. 

Another issue that Alocasia plants face is the falling of leaves. The leaves fall when they receive too less or too much sunlight. To avoid this issue, place the plant in a proper spot where it receives sufficient sunlight. 

Using low-quality or excessive fertilizer will result in the accumulation of minerals in the potting soil and can turn the plant’s leaves brown. To treat this issue, water your plant three to four times until the excessive salts are washed away.
