Water: Originating from temperate regions, corn buttercup thrives with a balanced watering routine, requiring weekly hydration for optimal health. It performs best outdoors, benefiting from seasonal rainfall, which aligns with its growth cycles and enhances its resilience to drought.

Fertilize: Corn buttercup requires balanced nutrition through fertilizers during active growth, switching to high nitrogen pre-flowering. Fertilize bi-weekly at recommended doses, reducing for young plants. Seasonal changes affect application frequency. Use granular or liquid forms and ensure soil moisture. Wear gloves for handling.

Pruning: Corn buttercup is a hardy annual with bright yellow flowers and lobed leaves. Prune in early to late spring to manage growth and enhance blooms. Remove dead or diseased parts and thin overcrowded areas for better air circulation, using sharp, clean tools to minimize disease risk.

Propagation: Corn buttercup thrives in disturbed soils, especially agricultural lands. Propagation is done by sowing seeds in well-drained, loose soil. Sow seeds sparingly to prevent overcrowding. Gentle watering is crucial for germination. With proper care, corn buttercup establishes quickly, growing into mature plants.
