Learn About Planting Allium Bulbs, The Graceful Globes Of The Garden

Alliums are an ornamental member of the Onion family. Their spherical blooms are made up of hundreds of tiny florets that are very attractive to bees and other pollinating insects. Because blooms appear at the top of tall slender stems, they look fabulous planted amongst lower growing plants. It’s easy to see why more and more of us are planting allium bulbs, as they bringing form and color to any garden. Dot throughout your beds and borders to add structure or plant in a container with tulips or other spring plants.


Planting Allium Bulbs: When To Plant Them

Alliums are amongst the most undemanding flower bulbs to plant, tolerating most types of soil and hardy down to zone 4. They should be planted in fall between September and November, before the soil freezes. You will rarely have to worry about watering them as they actually prefer dry conditions. Choose a sunny spot, water them when you plant them and then just wait for the lovely blooms in late spring and early summer.


Planting Allium Bulbs: How Deep Should They Be Planted?

Choose a spot with where the soil will not get waterlogged as alliums don’t like “getting their feet wet” as this may cause the bulbs to rot. Plant the bulbs about 3” deep and 6”- 8” apart: group them in threes or fives or scatter in drifts for a natural look.


Planting Allium Bulbs In Containers 

The stately forms of alliums look fabulous planted in pots and containers. You can plant them more closely than in the garden, just make sure there is good drainage and that the bulbs aren’t touching. Alliums are amongst the latest spring bulbs to bloom so they are ideal for extending the period of interest. Top tip: combine alliums in a pot with tulips and other spring-blooming plants such as daisies or pansies.
