Position your Alocasia 'Frydek' somewhere warm with bright but indirect light. Direct sun may scorch their leaves, and they will struggle over time if they're not receiving enough light.
As they originate from tropical climates, they do appreciate high humidity and warmth, so growing them in a bathroom or kitchen would be perfect (but not essential!).
Keep the soil fairly moist but allow the soil to dry out at least a third in between waterings.
When watering, thoroughly soak the soil until water drains out of the bottom of the pot. Discard any excess water in the saucer or decorative pot to prevent waterlogged roots.
In the winter months, reduce the amount of water you give your Alocasia, and don't be alarmed if it loses all its leaves. Alocasia's can go into dormancy as the temperature gets cooler and the days are shorter. It should push out new growth in Spring.
It's important to adjust your watering routine based on the time of year and specific environmental conditions like humidity and temperature.
