Water: Originating from temperate regions, narrow-leaved vetch thrives in moderate moisture, withstands low rainfall, and requires weekly watering. As an outdoor plant in meadows, it benefits from natural rain patterns that enhance its growth cycle through seasonal water variations.

Fertilize: For narrow-leaved vetch, use balanced fertilizers with higher nitrogen for growth. Apply quarterly, shifting to bi-monthly during active growth. Follow product guidelines to avoid over-fertilization. Adjust frequency seasonally, increasing in spring/summer and reducing in fall/winter. Conduct soil tests for tailored nutrition.

Pruning: Narrow-leaved vetch has slender leaves and purple flowers. Prune in early to late spring to encourage healthy growth by removing dead stems and ensuring proper air circulation. This practice promotes robust flowering, reduces disease risk, and maintains vigor for an attractive display throughout the growing season.

Propagation: Narrow-leaved vetch propagates by sowing fresh seeds in well-draining soil. A sunny spot encourages growth. Sow directly where narrow-leaved vetch will mature, as it does not transplant well. Lightly covering seeds and keeping soil consistently moist, but not waterlogged, supports germination.
