Growing Conditions

Planting Instructions
When planting star of Bethlehem bulbs, choose a location that meets their growing preferences. Dig a hole twice as deep as the bulb’s height and place it in the hole with the pointed end facing upwards. Fill the hole with soil, firm it gently, and water thoroughly.
Care and Maintenance
Once established, star of Bethlehem requires minimal care. Water regularly during the growing season, keeping the soil moist but not waterlogged. Mulching around the plants helps conserve moisture and suppress weed growth.
After the flowers fade, remove the spent flower stalks and trim any yellowing leaves. However, allow the rest of the leaves to wither naturally to ensure the bulb stores enough energy for future growth.

Ornithogalum can be propagated by dividing the bulbs. Lift the bulbs from the ground during the dormant period in the autumn and separate the offsets or bulblets from the main bulb. Replant the offsets at the same depth as the parent bulb.

Star of Bethlehem is occasionally susceptible to certain pests and diseases:
- Aphids: Small insects that feed on the sap of plants.
- Slugs and snails: Can eat through the leaves and flowers.

When purchasing ornithogalum bulbs, choose firm and plump ones with no signs of mold or damage. Look for reputable nurseries or online suppliers to ensure the quality and authenticity of the bulbs.
