Care Instructions
Erythronium grandiflorum requires moderate temperatures and indirect bright light for optimal growth. It prefers a humid environment and should be watered regularly to keep the soil partially moist. The plant goes dormant in the summer, so reduce watering during this period.Soil
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is rich in organic matter to support its growth. Good drainage is essential to prevent bulb rot.Fertilizer
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant in early spring before it starts to flower, and again after flowering to support bulb development.Repotting
Repot Erythronium grandiflorum bulbs every 2-3 years in the fall. Carefully dig up the bulbs, separate any offsets, and replant them in fresh, well-draining soil. Ensure the bulbs are planted at the correct depth, typically 2-3 times the height of the bulb.Propagation
Propagate Erythronium grandiflorum by dividing the bulbs in the fall. Carefully separate the offsets from the main bulb and plant them in a suitable location with well-draining soil. Water the newly planted bulbs thoroughly.Pruning
Pruning is not required for Erythronium grandiflorum. However, you can remove spent flowers and yellowing leaves to maintain the plant's appearance and health.Toxicity
Erythronium grandiflorum is not known to be toxic to pets or humans. However, it is always best to handle all plants with care and avoid ingestion.Additional
