Methods for Potting and Repotting Alocasia Regal Shield
Alocasia ‘Regal Shield’ thrives in containers, but it’s crucial to understand that these plants can be quite top-heavy. It’s important to select a pot that offers a stable base. These plants should be repotted every few years when they outgrow their current container. In such cases, simply opt for a pot that is a few inches larger than the current one. Ensure it has adequate drainage holes for excess water to escape. Carefully tilt the plant sideways, tap around the pot’s edges to loosen the roots, then gently remove the plant and transfer it to the new pot with fresh potting soil.
Wintering
When keeping this plant indoors, make sure to position it close to a well-lit window in the winter to guarantee it gets sufficient light. The plant might enter a dormant state, requiring less watering compared to the summer months. Refrain from using any fertilizer.
Elephant ear plants should not be left outside when temperatures fall below 55 degrees Fahrenheit. In such instances, remember to bring the plant indoors.
Types of Pests
Alocasia plants are susceptible to spider mites. To prevent this, ensure that the plant is not becoming excessively dry. Spider mites consume the plant’s sap, leading to yellow or brown discoloration of the leaves. They can also induce the formation of red bumps on the plant by releasing a toxin during feeding. The appearance of webbing on the leaves is a typical indication of a spider mite infestation.
