Commonly Asked Questions

What month is best to plant allium bulbs?

Allium bulbs should be planted in the autumn, ideally from September through December. Planting during this time allows the bulbs to establish roots before the ground freezes.

Do alliums come back every year?

Yes, alliums are perennials. Once planted in a suitable environment, they will bloom beautifully in the first year and return year after year.

Can you leave allium bulbs in the ground all year?

Yes, allium bulbs can be left in the ground year-round. Their seedheads can be left to provide winter interest or picked and dried for indoor decorations.

Do allium bulbs spread?

Some allium species spread through seeds or bulb multiplication. Varieties that multiply should be divided every three to four years by digging around the plant and lifting the bulbs.

Can I plant alliums in May?

While allium bulbs prefer early to mid-autumn planting, they can be planted in the UK from late summer until January, depending on weather conditions. Some varieties can also be planted in spring for later blooms.
