Ideal Temperature

Water: Flat pea thrives in temperate regions with moderate moisture and well-drained soil. Weekly watering prevents over-saturation or dehydration. It adapts well to varying rain patterns, making flat pea a resilient and versatile choice for diverse garden climates.

Fertilize: For flat pea, use a balanced fertilizer like a 10-10-10 mix in early spring, applying every 4-6 weeks until late summer. Adjust nutrients based on growth stages, and water before and after application to prevent root burn. Gentle incorporation into soil is crucial for optimal growth.

Pruning: Flat pea benefits from regular pruning, ideally in early to late spring as it enters active growth. Remove dead stems to promote health and blooms, avoiding heavy pruning to reduce stress. Pinching young shoots encourages bushiness while managing its vigorous nature.

Propagation: Flat pea is a perennial climbing plant noted for its vibrant flowers. Propagation involves sowing seeds in well-draining soil, with cold stratification to enhance germination. Maintain consistent moisture while avoiding waterlogging. Once established, flat pea self-seeds, offering low-maintenance floral expansion.
