Water: Grass pea originates from temperate regions and requires moderate watering, thriving with consistent soil moisture but not waterlogged. It prefers well-draining soil, suits outdoor cultivation, and needs adequate water during its growing season while adapting to local climate conditions.

Fertilize: For optimal growth, grass pea requires balanced fertilizers during planting and high-nitrogen options during active growth. Apply monthly in spring, increasing to bi-weekly as growth peaks. Use quarter-strength solutions and water grass pea before fertilizing to prevent root burn. Reduce applications as fall dormancy approaches.

Pruning: Grass pea is a climbing annual with fern-like foliage and pea-shaped flowers. Prune in early spring to enhance growth, remove weak stems, and improve air circulation. Use clean, sharp tools for precise cuts. Regular maintenance promotes healthy blooms and a vigorous appearance throughout the season.

Propagation: Grass pea is a resilient legume that thrives with proper propagation. Start with high germination rate seeds, sowing them in well-drained, moderately fertile soil at shallow depths. Maintain consistent moisture with gentle watering to prevent waterlogging, which is crucial for healthy development.
