ORIGIN
Alocasia, also known as "arrow leaf" or "elephant ear", is a genus of plants native to the tropical and subtropical regions of Asia and eastern Australia. They are particularly common in countries such as Malaysia, Borneo, the Philippines and New Guinea. These plants typically grow in moist, shady rainforests and along river banks.
CARE
Light:
Alocasia plants prefer bright, indirect light, but can also tolerate partial shade. Direct sunlight should be avoided as it can burn the leaves. They thrive in bright rooms with filtered light.
Temperature and humidity:
Alocasia plants love warm temperatures between 18°C and 27°C. They prefer high humidity, which is why they can thrive in bathrooms or kitchens. In drier environments, regularly misting the leaves or setting up a humidifier helps.
Irrigation:
These plants require consistent watering, keeping the soil moist but not wet. Waterlogging must be avoided as this can lead to root rot. Watering can be reduced during the winter months.
Floor:
A well-drained, loose potting substrate is ideal. A mixture of potting soil with perlite, sand or orchid bark ensures good drainage and aeration of the roots.
Fertilization:
During the growing season in spring and summer, a balanced liquid fertilizer can be applied every 4 weeks. Fertilization is less necessary in autumn and winter.
Growth type
Alocasia plants are evergreen perennials with striking, large, arrow- or heart-shaped leaves. The leaves often have prominent veins and can be green, silvery, purple or patterned, depending on the species. Alocasia plants reach heights of 30 cm to over 2 meters, depending on the species and growing conditions. They grow from underground rhizomes that can spread quickly.
More information
Repotting: Repot every 1-2 years in spring to give the plant fresh soil and encourage root growth.
Pest control: Alocasia can be susceptible to pests such as spider mites, aphids and mealybugs. Regular inspection and, if necessary, treatment with a suitable insecticide or natural remedies such as neem oil is recommended.
Dormant phase: Some Alocasia species can go through a dormant phase in which growth is slowed or the leaves partially die. During this time, watering should be reduced.
Toxicity: Alocasia plants are toxic to pets and humans if parts of the plant are ingested. It is advisable to keep them out of the reach of children and pets.
Alocasia plants are a popular choice for houseplant lovers due to their impressive leaf structure and exotic appearance. With proper care, they can remain healthy and decorative for many years.
