Couple of things on these:
Overwintering type - are they worth it.? I would suggest not, the sets i potted up this spring are already looking much healthier / bigger than the ones put in last october / november.
Planting out - This year we grew the sets in cells in the cold frame, as per Â鶹¹ÙÍøÊ×Ò³Èë¿Ú. Now planting out and wonder the best way to do so with the long straight root system. How deep etc.?
Hope you can help.
I've no experience of over wintering onions but I once over wintered broad beans & lost them to an April frost. An absolute waste of time. I set mine in a bed 6" apart just under the surface to stop the sparrows disturbing them.
I have grown overwintering onions for the past 2 years and I have decided not to bother again. I found that I was harvesting them about 3 weeks earlier than spring sown onion sets and I found that they did not store as well as the spring sown sets. I also tried overwintering broad beans and out of 3 years,I had to resow twice and the 1 year they survived, they were about 2 weeks earlier than spring sown beans, I live in Yorkshire and a different result might be had in the Southern counties.

A waste of time and space.
I've tried autumn sown onion sets for the first time. Frankly, I'm not impressed either. The conventional ones sown three months later are rapidly catching them up.
Interesting responses, jut confirms what I have found. What about the planting out from cells of the spring sets.? How deep should you plant them.? The straggly roots are almost as long as the green foilage.
I too planted 100 onion sets in a raised bed last september, and now 6 months later they look just like large spring onions so I don't know how much longer before I can dig them up.
This is my first attempt at growing onion sets and like other posts I feel it is a waste of time, space and effort planting in the autumn.
Will try in the spring next year.
The alternative, of course, is to grow them from seed. You have more choice of varieties and I also understand that they're less likely to bolt.
Last year I sowed some seeds for three types of onions and one lot were over wintered, but for some reason they all grew no bigger than a spring onion. One lot are still in a large pot from last September and we have recently had some in our salads. Perhaps I should try again as obviously I did something wrong.
