Black cardamom thrives in slightly acidic, rich, loamy soil. It’s a plant that prefers consistent moisture without being waterlogged, so regular watering is necessary, especially during the warmer months. However, it’s important to reduce watering frequency in the winter to prevent over-saturation.
This spice plant demands partial to full shade, avoiding direct sunlight to prevent growth stunting and foliage reduction. Temperature and humidity control are vital, with ideal temperatures between 72°F to 80°F (22°C to 27°C). Using a drip tray filled with pebbles and water beneath the pot can help increase ambient humidity.
Care and Maintenance
Fertilization is another critical aspect of caring for black cardamom. Apply a nitrogen-rich, low-potassium liquid fertilizer bi-monthly to support its growth. Regular monitoring for pests such as nematodes and thrips, along with diseases like capsule rot, will keep the plant healthy and productive.
Harvesting and Storage
Patience is key when it comes to harvesting black cardamom. Wait until the pods are mature before collecting them. Post-harvest, drying the pods in the sun is a common method to reduce moisture content, though it’s important to ensure they do not bleach out and lose their color.
