DETAILS

Care Instructions
Crinum americanum requires bright, indirect light and thrives in warm, humid conditions. It prefers consistently wet soil and should be watered frequently to maintain moisture. The plant does well in moderate temperatures and high humidity levels.
Soil
The swamp lily prefers loamy soil that retains moisture well. It is important to ensure good drainage to prevent waterlogging, although the plant can tolerate waterlogged conditions better than most.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season to support its nutrient needs. Reduce fertilization during the dormancy period.
Repotting
Repot Crinum americanum every 2-3 years or when the bulb outgrows its container. Choose a slightly larger pot and ensure the new soil mix is well-draining yet retains moisture. Handle the bulb carefully to avoid damage.
Propagation
Propagate the swamp lily by dividing the bulbs during the dormancy period. Separate the offsets from the main bulb and plant them in individual pots with a suitable soil mix. Ensure they are kept moist and in a warm, humid environment.
Pruning
Prune dead or yellowing leaves to maintain the plant's appearance and health. Pruning can be done throughout the year as needed. Remove spent flowers to encourage new blooms.
Toxicity
Crinum americanum is toxic to pets and humans if ingested. The bulbs and leaves contain alkaloids that can cause gastrointestinal distress and other symptoms. Handle with care and keep out of reach of children and pets.
