Water: Heartleaf skullcap thrives in consistently moist woodland settings, requiring weekly watering for optimal health. Once established, it demonstrates moderate drought tolerance. When grown indoors, maintaining humidity and soil moisture, especially during the growing season, is essential for supporting vigorous growth and lush foliage.

Fertilize: For heartleaf skullcap, use a balanced, slow-release fertilizer in early spring for optimal growth. Monthly applications during the growing season promote flowering, but avoid over-fertilization to protect root health. Reduce feeding in fall, and consider diluting to half-strength to prevent nutrient burn.

Pruning: Heartleaf skullcap is a perennial with heart-shaped leaves and blue flowers. Prune from early to late spring before new growth to enhance health and promote bushier growth. Regular maintenance, including trimming spent flowers and dead stems, supports blooming and maintains shape.

Propagation: Heartleaf skullcap propagates best through division during dormancy, ensuring each section has sufficient roots and shoots. Plant divisions in well-draining soil, maintaining consistent moisture without overwatering. With proper care, these divisions develop into healthy plants, preserving the characteristics of the parent.
