Growing pregnant onion babies, also known as Ornithogalum longibracteatum, involves providing the right soil, light, and watering conditions. Here's a detailed guide on how to nurture these unique plants:
Soil Requirements
The foundation for healthy growth of pregnant onion babies is well-draining soil. Here's what to consider:
- Organic Matter: A good soil mix should contain lots of organic matter. Coco coir is an excellent option to help retain some moisture while allowing the soil to drain.
- Drainage: It’s crucial that the soil drains well to prevent root rot. Add perlite or vermiculite to regular store-bought potting soil to improve drainage. A handful of perlite should suffice.
- Ideal Mix: Combine regular potting soil with coco coir and perlite or vermiculite for optimal results.
Planting and Care
Follow these steps when planting and caring for your pregnant onion:
- Choosing a Pot: Select a pot with drainage holes to avoid waterlogging.
- Planting the Bulb: Place the bulb (the "pregnant onion") in the pot, partially burying it, with the top of the bulb exposed. The smaller bulbs that grow at the base of the plant can be left to grow in the original pot or separated to create new plants.
- Light: Place the pot in a location that gets bright, indirect sunlight. Direct sunlight can be too harsh and scorch the leaves.
- Watering: Water the plant thoroughly when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to rot. Reduce watering in the winter months.
- Fertilizing: Fertilize sparingly with a balanced liquid fertilizer during the growing season (spring and summer).
- Temperature: These plants prefer warmer temperatures and do best when kept between 60-80°F (15-27°C).
- Propagation: The small bulbs (babies) that grow at the base of the mother plant can be separated and planted in new pots.
Summary of Requirements

| Drainage | Essential, use perlite or vermiculite |
| Light | Bright, indirect sunlight |
| Watering | When top inch of soil is dry, reduce in winter |
| Temperature | 60-80°F (15-27°C) |
By following these guidelines, you can successfully grow pregnant onion babies and enjoy their unique appearance.
