How to grow and care for Allium bulbs - Plant 20cm deep and 10cm or more apart
- Stagger the planting over a few weeks in the autumn and winter if you want to and this will result in the blooms opening up over a longer period in the spring
- Alliums do best in sunny sheltered spots whene the wind is less likely to do damage.
- once flowers are finished or faded leave the foliage in place as the plant will naturally draw nutrients from them back into the bulb for next year.
- You can cut them back to the ground once the leaves and stem have shriveled.
- best to plant alliums in amonst other plants so as to not have the leaves visible. The leaves tend to die off just before flowering.

- Feed alliums during the spring and summer and finally just as the flower is finishing.

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.
