Top Tips for Planting Allium Bulbs

Plant your alliums in autumn in a sheltered, sunny position with good drainage. You can improve drainage by raking the top foot of the soil mixing in several inches of peat or compost.

Allium bulbs should be planted 4 times the bulbs depth, in groups, spacing them about 8 inches apart for larger varieties and 4 inches for smaller double check on the bulb packet for exact spacing recommendations.

Add a layer of Bulb Planting Compost to prevent rotting.

Feed with slow release plant feed regularly throughout the growing season. Make sure you dead-head before seeds disperse to preserve strength.

Divide and replant overcrowded clumps after the foliage and flowers have died.
