Plant Care Instructions

6-8 inches (15-20 cm) tall and 3-4 inches (7-10 cm) wide
Light Requirements
Hyacinths prefer full sun to partial shade, with at least 4-6 hours of direct sunlight per day. Indoors, they should be placed in a bright, sunny window.

Hyacinths do not require fertilizer during the growing season, but can benefit from a balanced, all-purpose fertilizer applied in early spring before the flowers appear.
Pruning Guidelines
After the flowers have faded, the flower stalks can be removed, but the leaves should be left to die back naturally. This allows the plant to store energy for next year's growth.
