Water: Heartleaf Arnica thrives in moist montane zones, requiring consistently moist soil. It prefers weekly watering to prevent prolonged dryness. As an herbaceous perennial, it flourishes outdoors, with adequate hydration essential for robust flowering and overall vitality during its growing season.

After seedlings harden, transplant them into individual pots to support root development before placing them in their final location.
