This outdoor plant is resilient to fluctuating conditions, effectively utilizing sporadic rain during its active growing season.

Fertilize: For purple vetch, use balanced nutrition fertilizers early in the growing season for root establishment. Transition to high nitrogen fertilizers during vigorous growth and bloom phases, applying monthly. Reduce applications during dormancy. Wear gloves and water purple vetch after fertilization for best results, ensuring strong development and abundant blooms.
