Growing Information

Light Requirements: Plant in full sun for the best flowering, although partial shade is also suitable, particularly in warmer locations.

Watering: Water after planting and during active growth as needed. Keep the soil lightly moist while avoiding waterlogged conditions that can cause bulbs to rot.

Planting: Plant bulbs in fall, pointed end up, approximately 10–15 cm deep and 10–15 cm apart. Choose a location with good drainage.

Maintenance: Remove faded flower spikes after blooming. Allow the foliage to yellow and die back naturally so the bulb can replenish its energy for the following season.

Long-Term Care: Hyacinths can return in subsequent seasons, although flower spikes may become smaller over time. Allow foliage to mature fully before removing it, and avoid planting in areas where water collects.
