Autumn Planted Onion and shallot sets?

go for autums, planted last year and it came out really well so planning on some more this year

and if you need any back up evidence : the last two years running our Autumn sown onions sets have performed very well indeed.

Shallots have been a bit variable tbh and although nothing special have been OK

Garlic very good on the whole too 

Autumn planting Onions are a great filler gap for a few weeks before the main crop are ready. I do them every year and start eating as green onions on 1st May every year..

Shallots are normally planted on the shortest day and pulled on the longest day.. had good results for these as well. Also ready before the main crop. I found some for planting now on the instructions so trying them as well this year.

when can i start planting out the shallots, Japanese onions and garlic?

I plant autumn onion sets and elephant garlic. Fill in the spaces in spring. It's one less area to worry about come spring when there's enough to do anyway.
