Soil Type
Water: Crowpoison thrives in well-drained soils and prefers a moderate moisture regime, requiring weekly watering. This bulbous plant is commonly cultivated outdoors and benefits from seasonal rains that align with its growth cycles, ensuring optimal hydration during active periods.
Fertilize: For optimal vitality, fertilize crowpoison with a balanced formula quarterly at 1 teaspoon per gallon during vigorous growth in spring and summer. Reduce in fall and winter, and ensure soil is moist to avoid root burn. Adjust fertilization according to seasonal growth cycles.
Pruning: Crowpoison is a resilient bulbous plant featuring grass-like leaves and star-shaped flowers. Prune from early to late spring, removing dead foliage and spent blooms to stimulate growth. Use clean, sharp tools for pruning to prevent disease and manage size, ensuring optimal health.
Propagation: Crowpoison propagates easily through tubers, ideally in Spring. Successful growth is signaled by new shoots. Careful handling of tubers is crucial to prevent damage.
Repotting: Repot crowpoison every 2-3 years in spring, using well-draining soil and a pot with drainage holes. Ensure the pot is appropriately sized for root growth. After repotting, water sparingly and provide bright, indirect light for optimal recovery and growth.
