Water: Tuberous pea originates from temperate regions and thrives in moderate moisture levels. It requires weekly watering but can tolerate brief dryness. As an herbaceous perennial, tuberous pea prefers outdoor settings to benefit from natural rainfall during its active growing season.

Fertilize: For optimal growth, tuberous pea requires balanced fertilizers during spring and late summer at half strength. Light, regular applications enhance growth and flowering, while over-fertilization can harm tuber development. Adjust feeding amounts seasonally, using liquid fertilizers for even distribution to maintain a healthy tuberous pea.

Pruning: Tuberous pea is a perennial vine that features attractive flowers and tuberous roots. Prune between early to late spring to promote healthy growth and blooming. Remove damaged stems and thin overcrowded areas, but avoid heavy pruning to prevent plant stress. Consult reliable sources for specific guidelines.

Propagation: Tuberous pea propagates well through sowing healthy, disease-free seeds in well-drained, organic-rich soil. Scarifying the seed coat can improve germination. Plant seeds a couple of centimeters deep and maintain consistent moisture without waterlogging. Ensure stable conditions and proper light for optimal growth.
