How to care for Allium Mount Everest & Allium Purple Sensation
This allium collection is happiest in direct sunlight.
Remove foliage when it becomes untidy, it won’t do the Allium any harm.
If soil is looking very dry in the spring, we suggest watering. Be careful as pots dry out quicker than borders.
Plant with lots of good quality, peat-free compost for best results.
This allium collection likes soil to be well-drained, try to mix in grit when planting.
How to plant an allium bulb
When is the best time to plant an allium bulb?
Plant allium bulbs between early September and early December.

Plant large bulb varieties around 15cm deep. For smaller bulbs, we suggest 10cm deep.
Most bulbs should be planted at a depth of roughly 2-3 times their own height.
How should you space your allium bulbs?
Smaller allium bulbs should be planted 8-10cm apart. Large bulbs should be planted around 15-20cm apart to allow their flower heads to shine.
For the XL varieties such Allium Globemaster, allow 30-40cm between each bulb.
Which way should the Allium bulb face?

Any other tips for planting bulbs?
For best flowering results, store bulbs in a cool, frost free, place until you are ready to plant them. Remove bulbs from their packaging so they can get some fresh air, but make sure your pets don’t nibble them. It is important to plant bulbs within the same season that they are supplied.
