However, despite their common name, spring onions can be sown anytime from March to September and even as late as October. Provided they are sown in the ideal conditions.

How to Sow and Grow Spring Onions
We recommend beginners to sow indoors in October as plants and seedlings are sensitive to the potentially frosty weather. Sow seeds in trays of compost ½ an inch deep, covering them with ¼ inch of compost. Keep the seeds moist and within a temperature between 15 to 18 °C. They should start to germinate from 7 to 14 days.
Sow seeds thinly into shallow drills 1.5cm deep, with rows spaced 30cm apart. Water and keep the seed’s environment moist. Once the seeds have germinated and developed into a substantial young plant, cover them with cloches and use a cold weather fertiliser to support their development and protect them from frost damage in the autumn/winter season.
Please note that once transplanting spring onions outdoors, they should be spaced 30cm apart as per sowing outdoor instructions.
