How to Care
- Alliums are drought tolerant and watering of plants grown in the ground is not usually necessary. Plants dislike summer irrigation because this may cause the bulbs to rot. Alliums grown in containers will need regular watering, but make sure the compost does not become waterlogged.
- Regular feeding is not necessary but on poor soils, apply balanced fertiliser such as Growmore in spring.
- You can cut off the spent flower heads at the base but this is not essential as the dried flower heads look attractive in the border.
