Water: Common vervain flourishes in moderate moisture, preferring neither extreme dryness nor excess humidity. It requires weekly watering and thrives outdoors, benefiting from natural rainfall as an herbaceous perennial.
Fertilize: For optimal growth, common vervain requires balanced nutrition fertilizers bi-monthly in the growing season, switching to high phosphorus as blooming approaches. Use fertilizers sparingly to avoid root damage, especially for younger plants. Adjust frequency seasonally and always water thoroughly after application to distribute nutrients and prevent root burn.
Pruning: Common vervain features slender stems and delicate purple flowers. Prune in early to late spring to promote fresh growth and bushiness. Remove dead stems for plant health. Regular pruning enhances flowering and prevents legginess, with optimal timing during the plant's active growth phase for recovery.
Propagation: Common vervain is a hardy perennial herb characterized by slender stems and pale lilac flowers. Propagate by dividing root clumps and planting them in well-draining soil with consistent moisture. Once established, common vervain tolerates various soil conditions, suitable for novice gardeners and expanding collections.
