Plant Information

Top Tips

Underplant with hostas, ferns or other low-growing, hardy perennial plants which will help to disguise the leaves as they fade.

Care Guide

Planting Advice for Allium Globemaster:

  • Find a location where the soil drains well and where they will receive full sun.
  • Plant allium bulbs in early to mid autumn in a sheltered site to prevent the top-heavy flower spikes from getting blown over.
  • Dig over the soil and remove any weeds before planting.
  • Water well after planting, saturating the soil around the bulbs. Once established, alliums are drought tolerant.
  • In borders, plant bulbs in early autumn at a depth of about four times the diameter of the bulbs.
  • In containers, alliums will do well in deep pots with a good general-purpose potting compost with a handful of horticultural grit added.


 

Aftercare Advice for Globemaster:

  • After planting, feed with a general-purpose feed such as our Blooming Fast Superior Soluble Fertiliser.
  • Dried flower heads can be removed and made into indoor decorations or left on the plants to self-seed.
  • Divide alliums every three to four years or when the plants begin to look overcrowded and blooming decreases.
  • Lift the bulbs with a garden fork or spade and pull the bulbs apart.
  • Replant some in the original location and plant the remainder in a new location.

 

Pruning and trimming advice for Alliums:

  • The leaves die down at flowering time, so itís best to plant alliums where this foliage is masked by that of other plants.
  • Avoid removing them while still green, as they provide the bulbs with energy for the following season.
