    Watering Keep the soil consistently moist while the crop is establishing and growing, especially during flowering, fruiting or rapid leafy growth. Water deeply at the base rather than little and often, allowing excess water to drain away. Plants in containers, grow bags or greenhouses may need daily checks during warm weather.

    Best Growing Conditions Grow in sun or partial shade in sandy, enriched with organic matter where appropriate. Choose an open position with good airflow and enough space for the crop to mature without excessive competition. Protect tender crops from late frost and cold winds, and use greenhouse or sheltered growing conditions where the variety requires extra warmth.

    Top tip

    Keep the bed weed-free while plants are young, as alliums compete poorly with vigorous weeds around their shallow roots. It works particularly well in an allotment setting; give it enough space and light to develop naturally rather than crowding it.
