Allium 'Summer Drummer'

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.

Feed a general fertiliser

Give a general purpose feed two or three times during the growing season, preferably not within a month of its end so the plant isn't encouraged to make fresh young growth.

Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.

Spring-Autumn · Outdoors

Water during dry periods

For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.

Spring-Summer · Planting

Bulb foliage

Allow foliage to die back naturally to enable energy to be returned to the bulb for the next year. Once leaves are yellow, dried and flopping over, usually about 6 weeks after flowering, cut or mow back to the ground.
