When to plant allium bulbs

To ensure optimal growth, it's important to plant allium bulbs in the best possible contidion for them to thrive, these include:

  • Plant allium bulbs from September to mid-November, with an acceptable planting period extending until mid-December, weather permitting.
  • Choose a sheltered spot with well-draining soil and ample sunlight for your allium bulbs. Their tall flowers will stand proudly, unaffected by strong winds. Remember, alliums belong to the onion family and appreciate sunlit conditions.

How many allium bulbs should I plant together?

  • Giant alliums need lots of room and sun to grow. You can plant them at least 15-20cm apart and 15cm deep
  • Medium sized alliums like Purple Sensation can be planted 10cm deep and 10cm apart.
  • Small alliums such as Drumsticks can be planted close together, 5-8cm deep and 5cm apart.

Tips for growing alliums

Although alliums are easy to grow, there are some factors that you should consider when growing these striking flowers, such as:

  • Allium bulbs can stunt the growth of beans and peas – dont plant them too close together.
  • Allium leaves are often very large and can suffocate smaller plants too close – make sure you give them lots of room.
  • As allium flowers begin to grow, foliage will begin to die. It is best to plant alliums behind smaller plants such as hostas to hide the dying leaves.
  • It is better to plant large alliums in beds, not pots.
