Growing onions - rotate or not

[yorkshire sam]

I grow lots of onions and while I normally rotate crops I am debating making a bigger bed solely for growing onions for store.
Which methods do others use?

I always rotate as there is the danger of onion white rot disease.

I decided that since my shallots did so well in my raised bed last year I would dig in some sand this year and grow onions and shallots (and garlic) in the same bed this year. Will watch the results and then decide what to do next year (if we are still in this house)

i have veggie patch in garden and an allotment
i've grown winter onions on the allotment - they will be rotated, being planted in the bed that the potatoes come up from
in the garden i have a 24ft x 10ft veggie patch - this is divided into 3 veggie patches of 8ft x 8ft and a 24ft x 2ft onion and garlic bed - this is a "permanent" onion bed - if i get onion rot, i'll move the onion bed to the opposite side of the veggie beds
(hope that makes sense!)

I rotate my main bed, but stick extras in wherever I can as I run out of space.

Chances that they hit the exact same spot are minimal, and as long as I avoid beds that have had any rot [which I know off by heart]....then I'll keep reusing them until they do.

i always rotate my main crop but have used the same bed for my winter onions for years and i have never had any problems

I used to practice monoculture with onions/leeks and carrots but unlike the Robinson giant onion people who have been growing in the same beds for a hundred years or more, I found I was getting diminishing returns!
If you are prepared to muck the onion trench every year and add the required nutrients it IS possible, but to be honest I can't be arsed and my reversal in thinking and insisting on two crops a year for each area plus clump growing of mixed vegetables/flowers/herbs seems to be working a treat!

You can end up with onion rot and no crop at all. Our allotment site has soft rot - who wants a snotty-nosed onion?

It's probably more bother to rotate but worthwhile in the end.
