When to plant Allium Bulbs

Allium bulbs should be planted in the autumn, between September and November. This timing allows them to develop roots before the onset of winter, ensuring a stunning display of flowers in late spring to early summer.

How to Plant Allium Bulbs

To plant allium bulbs, choose a sunny spot with well-drained soil. Plant the bulbs about 4 to 6 inches deep and 6 to 8 inches apart, depending on the variety. Ensure the pointed end is facing up. Cover with soil, firm gently, and water well. Alliums benefit from a layer of mulch to protect them during winter and retain moisture.

How long do Allium Bulbs take to grow

Allium bulbs typically take 12 to 14 weeks to establish after planting. They will bloom in late spring to early summer. The exact timing can vary based on the variety and growing conditions. After flowering, let the foliage die back naturally to help the bulbs store energy for the next season.
