How to plant Alliums

• Plant Alliums in the Autumn for Spring flowering.
• Choose a location to plant your Allium Bulbs, they like to be in full sunlight and well-drained soil.

Planting Alliums in the Garden

• Once you have found the perfect spot in your garden to grow your Alliums, you need to dig holes in the flower bed that are three times the diameter of the bulb. For example, if the bulb is 5cm (2") in size then it needs to be planted 15cm (6") deep.
• Plant the bulbs about 20-30cm (8-12") apart. For impact, plant in groups.
• Alliums work well in rockeries and crowded gardens as they don't take up much space.
• Add horticultural grit to heavy soil to improve water drainage. 
• The Allium bulbs need to be planted pointy end up.
• Water the bulb well once in situ.
• To help the soil drain well it is also beneficial to spread mulch, wood chips and organic matter over the entire planting area.
• Alliums will flower around May/June.
• Cut the Alliums back at the end of their blooming season. They will then continue to grow in your garden year on year with very little maintenance.

Planting Alliums in Pots 

• Plant Alliums the same depth for pots as in the garden. Plant three times the diameter of the bulb. For example, if the bulb is 5cm (2") in size then it needs to be planted 15cm (6") deep.
• For a garden with limited space, you may want to produce a fuller pot display of spring flowers by layering your bulbs like a lasagne. Simply plant your bulbs deeper to start with, with the largest or latest flowering bulbs further down, moving to the smallest and earliest flowering in the top layer. The shoots from the lower bulbs will find their way around the other bulbs. If you are planting the Alliums first, allow 10cm (4") of soil underneath the bulbs.
• Use a good-quality, multipurpose compost. 
• Add horticultural grit to heavy soil to improve water drainage. 
• The Allium bulbs need to be planted pointy end up.
• Water the bulb well once in situ.
• To help the soil drain well it is also beneficial to spread mulch, wood chips and organic matter over the entire planting area.
• Alliums will flower around May/June.
• Cut the Alliums back at the end of their blooming season. They will then continue to grow in your garden year on year with very little maintenance.

How to care for Alliums

• Add a potash feed to enhance growth and strengthen the bulbs for flowering year after year.
• Allow flower to die back and remove any dead foliage in early Summer.
• Remove any dead stems that become detached from their bases.
• Alliums are hardy and can therefore be left in the ground all year round.
• Keep an eye out for any diseased foliage.
• Seldom need support.
