- Reliable, early maturing variety – Stuttgarter Giant is known for its dependable performance in UK conditions, producing firm, golden skinned bulbs that store exceptionally well through autumn and winter.
- High yielding and full of flavour – This traditional favourite offers a generous crop of medium to large onions with a strong, classic flavour ideal for cooking, pickling, and everyday kitchen use.
- Easy to grow for all gardeners – Suitable for beginners and experienced growers alike. Plant January to April (winter to early spring) and harvest in late June to July, about one to two weeks after the leaves begin to yellow. Choose a dry day to lift them gently with a fork. Store in a cool, dark, well-ventilated place if not planting immediately.

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 fertile loam, 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.
