Background

Chives are a hardy perennial herb grown for thin, hollow, onion-flavoured leaves and edible purple pompom flowers in late spring. They return reliably each spring through hard winters, are among the first herbs up and the first to be picked, and ask for almost nothing, which makes them a staple of any kitchen garden and a good edging plant in the flower border too.

Sow in spring or set out divisions 6 to 8 inches apart in average soil that drains, in sun or part shade. Cut the leaves an inch above the ground as you need them; the more you harvest, the more the clump produces, and a clump cut hard in midsummer comes back fresh. The flowers slow leaf production, so remove them if you want leaves, or let them come for the bees and scatter the florets over a salad.

Clumps expand over the years and should be divided every three or four years in spring or fall. A pot of chives brought indoors in late winter, after a cold spell, gives fresh leaves weeks early. Deer and rabbits leave onions alone, and chives have no pests worth naming. Garlic chives (Allium tuberosum) are a different plant with flat leaves and white flowers in late summer.

Common problems

Downy mildew

Symptoms

Yellowing on top of leaves with grey-purple fuzz underneath. Spreads rapidly in humid conditions.

Treatment

Remove affected leaves. Improve air circulation. Avoid overhead watering. Copper spray as preventive.

White Rust

Symptoms

Raised white to cream-colored pustules on leaf undersides, with yellow blotches on upper surfaces. Infected tissue may swell or distort.

Treatment

Remove and destroy infected leaves. Improve air circulation and avoid overhead watering. Rotate brassicas and avoid planting in previously infected soil.

Pests

Aphids

Aphididae →
Symptoms

Clusters of small soft insects on new growth and flower buds.

Treatment

Knock off with a strong jet of water. Ladybirds and lacewings are natural predators. Insecticidal soap as last resort.
