If you want the best possible outcomes, you should schedule this work for the spring and summer, when growth is at its peak. After the blooms on your Variegated Alocasia have faded, you can harvest the mature seeds and scatter them over the garden.

In order to redirect the plant’s resources into leaf development, some farmers pick off the blossoms before they fully open. However, they emit a pleasant scent that you should absorb if at all possible.

Humans should keep a distance from variegated Alocasia plants. Children’s innate curiosity makes them more inclined to try tasting the leaves, increasing the risk that they will ingest some of them. There is less likelihood of a severe reaction if they have only had a small amount of food. However, if they have difficulty breathing or their tongue or lips swell, they need immediate medical assistance.

The sap from a Variegated Alocasia may cause irritation to the skin, and if it gets into the eyes, it can cause discomfort that lasts for hours. Soap and water can be used to clean the afflicted skin and remove any harmful microorganisms. A rash can also be treated with a lotion applied topically.

There are a few prevalent problems that the Alocasia Macrorrhiza Variegata might be experiencing. If you want answers to some of those questions, stay reading this article until you get to the end of it.

Pests and Diseases

Spider Mites

Because of spider mites, the leaves of the Alocasia Macrorrhiza Variegata plant begin to fall off. These bugs not only make the leaves darker, but they also leave behind streaks and spots on the surface of the leaves. It might be difficult to find spider mites with the naked eye, but you can recognize them by the thin webs that they spin on the underside of the leaves. They can be efficiently eradicated with the use of neem oil or an insecticidal soap.

Spider mites thrive in arid environments; to prevent their infestation, please maintain a high level of humidity surrounding the plant. It is possible to spray a solution consisting of Neem oil, dishwashing soap, and water. Spray the mixture generously all over the leaves, including the undersides of the leaves.


Mealybugs are a type of little insect that feeds on nectar and may do a significant amount of damage to your macrorhizos. The consistent use of neem oil and insecticidal wash can assist in the eradication of these pesky insects.


Thrips are very little insects that have wings and can fly. They frequently cause white spots to appear on the foliage and petals, and the excrement they leave behind leaves the foliage with very minute black markings. Controlling thrips is typically difficult to do. To get rid of them, you should employ a strategy that includes neem oil, pesticidal soap, and sticky traps.

Fungal Leaf Blight

The fungal leaf blight disease can cause lesions on the leaves, which then cause the leaves to secrete fluids. If this infection is not treated as soon as it appears on a plant, it can cause the plant to wilt and potentially die if it is left untreated. In order to effectively fight fungal leaf blight, early diagnosis is essential. Every other week, spray a fungicide that contains copper on the area that is affected by the infection.
