Alocasia lauterbachiana is a moderately easy plant to care for. It prefers bright, indirect light and high humidity. Overwatering can cause root rot, so allow the soil to dry slightly between waterings. Regular misting helps keep humidity up, and occasional feeding during growing season supports healthy growth.
