Growing Onions from Seed

Whilst growing onions from seed requires more patience than planting onion sets or onion plants, many home gardeners consider the benefits well worth it. Sowing onion seeds is not only more cost-effective, but it can also result in larger bulbs due to the extended growing season. 

Our range of onion seeds includes various varieties to suit different culinary needs. Yellow onions are great all-rounders for cooking, while red onions are sweeter – ideal for eating raw in salads. Spring onion seeds are quick-growing and add a fresh flavour to Asian dishes and garnishes. White onions, less common in the UK, offer a unique sharp and tangy taste.

Sow onion seeds outdoors in early spring, or indoors in winter, and you’ll be rewarded with delicious bulbs from August onwards.
