Watering. Water when the top inch of soil feels dry. Avoid letting the plant sit in water to prevent root rot. Increase watering frequency in warmer months and reduce in cooler months.
Fertilizing. Feed with a balanced liquid fertilizer every 4-6 weeks during spring and summer. Reduce feeding in fall and winter when growth slows.
Alocasia plants prefer bright, indirect light and high humidity. They need regular watering but the soil should not stay soggy. They can be sensitive to cold and drafts, so keep them in a warm spot. Occasional feeding during the growing season helps them thrive.
