overwintering red onions

It's sometimes surprising to find that we're planting onions in November. They're most usually thought of as plants of the high summer, heaving themselves out onto the baked soil, ready for harvesting in late summer.
The arrival of Japanese onions some years ago changed all that.
These red onions were dobbed into the ground in November as onion sets and will steadily and slowly establish themselves ready for sustained growth in spring and early summer. They'll be harvested in June, leaving the ground free for another crop.
These horrible warm winters play well with overwintering onions. I'm hoping for a bumper crop!
