Why grow Alliums?
Alliums are tough, perennial bulbs (related to onions, shallots and garlic) that produce an excellent range of cut flowers or blooms for dried bouquets. They are hardy and easy to grow, with tall elegant stems that don’t overcrowd an area, making them perfect companions to other flowering annuals and perennials in any garden.
Where do I plant Alliums?
- Allium bulbs are remarkably tough, drought-resistant and will grow best in full sun.
- It is best to plant them somewhere you are unlikely to dig over, so that you don’t disturb them, as once planted, they can multiply naturally, and can be left untouched in the same area for years.
- They make an excellent addition to an ornamental border, and can be clumped together to give a block of colour along pathways, or used as layers of colour in larger beds, you can also mix them in with other flowers to add depth of colour.
How do I grow Alliums?
- Plant alliums in mid-Autumn in well-composted, free-draining soil that is slightly acidic.
- Plant allium bulbs in holes about 2 to 3 times as deep as their diameter.
- Water them regularly during dry spells but take care not to over-water as this may cause the bulbs to rot.
- After flowering, you can remove the deadheads, if you want, or leave them as they still add interest. Leave as many leaves as possible to put goodness back into the bulb for the following season.
- Alliums are fairly slow to multiply, but once the flowers have finished you can lift the bulbs if you choose, and remove the offsets for replanting immediately, although it may take a couple of years for these offset bulbs to flower.
