Time to plant your Japanese onions
Gardening with MAT COWARD

ONE of the most useful vegetables you can sow at this time of year is overwintering onions, also known as Japanese onions, because that’s where the original cultivars were bred. 

They are bulb onions — similar to, though generally a bit smaller than, familiar maincrop types — but they’re winter hardy and need less light than summer varieties.

Sown in August, planted out in September, they’ll be ready for eating early next summer.
