Allium 'Millennium'

Autumn · Planting

Remove offsets to create new plants

Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water after 2 weeks of no rain

Established plants in the ground enjoy dry or well drained soil, but don't survive long periods without water. When there's been no rain for a fortnight, do a deep water. Repeat after 1-2 weeks when the soil has dried out. Check plants in pots more often.
