Growing onions from seeds is a rewarding and straightforward process that can yield a plentiful harvest. Onions are not only a kitchen essential but also beneficial for crop rotation, improving soil health for future planting. Whether you're a novice gardener or an experienced grower looking for tips on growing exhibition onions from seed, take advantage of our helpful tips below.

Which spring onions grow fastest from seed?

Spring onions that grow fast from seed include varieties like 'White Lisbon' and 'Ishikura'. These types can be harvested in as little as eight to ten weeks from sowing, providing a quick and reliable crop.

Should I soak onion seeds before sowing?

Soaking onion seeds before sowing is not necessary, but it can help speed up germination. If you choose to soak them, place the seeds in water for 12 to 24 hours before planting. This process softens the seed coat, making it easier for the seeds to sprout and establish more quickly.

Can you plant onions and shallots together?

Yes, you can plant onions and shallots together as they share similar growing requirements. Both need well-drained soil, plenty of sunlight and regular watering. However, ensure they have enough space to grow. Proper spacing and crop rotation are key to a healthy and productive garden.
