Alocasia Regal Shield Care: Know the Origin, First!
The Alocasia Regal Shield is a cultivated variety that originated as a man-made hybrid, not occurring naturally in the wild. It was developed by crossing several different Alocasia species, including Alocasia macrorrhiza and Alocasia sanderiana.
The goal was to create a plant that had the most ornamental features from each parent plant, resulting in the dramatically shaped, beautifully veined leaves that Alocasia Regal Shield is prized for.
This tropical plant was first created by plant breeders in Philippines nurseries in the late 1900s by selectively breeding different Alocasia types. Since then, it has become a beloved houseplant around the world thanks to its exotic, tropical appeal and its ability to thrive as a container plant indoors.

All Growing Traits of Alocasia Regal Shield
I’ll talk about all the key things you need to know to grow your Alocasia indoors.
Lighting
Alocasia ‘Regal Shield’ thrives in bright, filtered light. When grown indoors, place it near an east, west, or north-facing window where it will receive plenty of gentle sunlight. Slowly acclimate the plant if moving it from a low-light area. Rotate the pot weekly so all sides get even light exposure.
If kept outside, situate in partial or dappled shade. The morning sun is great, but avoid the intense afternoon sun which can scorch the leaves.
Soil Preference
Well-draining, loamy soil with a slightly acidic pH is ideal for Alocasia ‘Regal Shield’. The soil should retain some moisture but not get waterlogged.
Mix in materials like perlite, bark chips, or coconut coir to improve drainage. Or use an aroid-specific potting mix. Test drainage by watering the plant well and checking 15-20 minutes later that excess water flowed out of the pot’s drain holes.
Watering Frequency
These tropical plants appreciate consistently moist (but not soggy) soil. Allow the top few inches of soil to dry out between waterings, then soak the pot completely. In summer, this may mean watering 2-3 times per week. In winter, reduce frequency.
Always check soil moisture with your finger before watering. If the soil feels dry and the plant looks droopy, it needs a drink. But take care not to overwater, as that can lead to root rot.
Temperature And Humidity
Warm and humid! These jungle natives thrive with daytime temps of 70-85°F and 60-70°F at night. Maintain at least 50% relative humidity. Use a humidifier, pebble tray, or regular misting to increase moisture in dry air. Avoid cold drafts.
If outdoors, grow Alocasia ‘Regal Shield’ in Zone 9-11 only. Move indoors before temps dip below 60°F.
Fertilization
Yes, fertilizing monthly in the growing season will promote lush growth.
Use a balanced liquid fertilizer diluted to half-strength. Or work some worm castings or compost into the soil. Discontinue fertilizing over winter when the plant goes semi-dormant. And never fertilize a stressed plant. Overfertilization can damage the roots.
Pruning And Shaping
Remove any old, damaged, diseased, or dying leaves at the base of the plant. Pruning helps direct the plant’s energy toward new growth. You can also cut off the main trunk after a few years of growth to encourage side shoots and a bushier appearance. Sterilize pruners before each cut with isopropyl alcohol.

How Can I Propagate New Alocasia ‘Regal Shield’ Plants?
These tropicals propagate easily through division. In early spring, uproot the plant and cut off younger side shoots (“pups”), making sure each has some roots attached. Replant the pups in small pots with well-draining soil. Keep warm and humid while they establish. Soon you’ll have brand new elephant ear plants!

Why Is My Alocasia Leaves Turning Yellow or Brown?
If older leaves turn yellow or brown while new growth looks fine, this is likely natural dieback. But yellowing along leaf edges or margins indicates overwatering. Brown crispy spots equal low humidity. Small brown spots may signal a fungal or bacterial infection.
So, isolate affected plants and treat them with a fungicide. Severe leaf damage usually requires replacing the plant.
How Do I Treat Pests on My Alocasia ‘Regal Shield’?
Check regularly for signs of infestation like sticky honeydew residue or webs on the leaves which indicate scale, mealybugs, or spider mites. Treat with insecticidal soap, neem oil, or horticultural oils. Repeat applications may be needed.
Maintain optimal growing conditions to avoid stressed plants that attract pests. Removing affected leaves can help contain the spread.
Why Isn’t My Alocasia ‘Regal Shield’ Blooming? How Can I Encourage Flowers?
Flowers are uncommon with these stunning foliage plants. And the plant needs to mature – around 3-5 years old – before it will bloom. Maximize chances by providing excellent care, consistent warmth and humidity, and bright light. Fertilize regularly in spring and summer.
Pinch off any flower stalks that form to help the plant conserve energy. But don’t be alarmed if your Alocasia never flowers. The leaves are the real showstoppers!
Is the Alocasia ‘Regal Shield’ Toxic or Dangerous for Pets or Kids?
Yes, unfortunately, all parts of this plant are highly toxic if ingested and can cause mouth irritation, vomiting, and difficulty swallowing or breathing. Keep out of reach of curious pets and children. Wear gloves when handling, as the sap can irritate skin. Seek medical help immediately if plant parts are swallowed.
Conclusion

Its fabulous foliage is well worth the effort. The ‘Regal Shield’ elephant ear is sure to become your new favorite plant.
