Care Guide

💧 Water
☀️ Light Full sun

Calathea thrives in full light but also tolerates partial illumination. Coming from areas with plentiful sunshine, proper light considerably benefits its health and growth. Nevertheless, both excessive and inadequate light can harm its well-being.

Ideal: Full sun
🌡️ Temperature 20–37.8°C

Calathea comes from tropical areas, where the weather is generally warm and humid. Consequently, it is well suited to high temperatures and moisture. It does not tolerate sudden temperature shifts and prefers a steady temperature, so avoiding fluctuations indoors is important. It usually cannot endure cold conditions and needs warmer temperatures for growth. If the surrounding temperature falls too low, the plant may stop growing or even die.

Ideal temperature: 20–37.8°C

🌱 Fertilizer

Proper fertilization is essential for a Calathea's health and appearance. Fertilize Calathea in the summer, repeating the application monthly throughout the season. Nutrients provide energy for growth and help maintain the plant’s tissues. Regular fertilizing improves Calathea’s flowering, ensuring it produces the best blooms.

🪴 Pot & Repot 3-4 years

To repot a Calathea, pick a pot slightly larger than the previous one that provides good drainage. Repot during spring or fall, and use a well-draining potting mix. Plant it at the same depth as before. Thoroughly water the plant after repotting and place it in a warm spot with bright, indirect light. Avoid overwatering to prevent root rot.
