Crop Rotations in raised beds


My raised bed crop rotation consists of Bed 1: Brassicas

Bed 2 Legumes and onions, strawberries

Bed 3 salad, parsnips, sweet potatoes, carrots, radish

Where in my rotation could I add another extra raised bed of white red and japanese onions, as I dont have enough room in my present bed of legumes to grow enough onions?

    Rosie, crop rotation goes thus Legumes and all pod crops should be followed by Brassicas, ie:- cabbage cauli Sprouts and other green plants, They are followed by Root crops Carrots Parsnip Beetroot etc. They are followed by the Onions Leeks shallots etc.
    So it is Legumes, Brassicas, Root crops and then Onion crops.
    Well that is the rule which we all bend to fit everything in and rotation for my Father a very keen gardener also meant a fifth bed left fallow for a year or to grow green manure, the ducks hens and geese would be let loose on that patch from time to time to scratch it over.
    The answer to your question would be a separate bed for the Alliums or Onion crops depending on whether you grow Scallions Leeks Pickling onions and Garlic.
    Hope this helps.

    I like the acronym People Love Bunches Of Roses as an aide memoir for crop rotation. Potatoes, Legumes, Brassicas Onions/Roots.

    Thanks for all the great advice, especially Frank.  I will do that frank.  If I out in an extra bed of say japanese onions this September, can I then following on with red and white onions next spring before leaving the bed fallow or growing the green manure in its place for a season or would I have to leave it fallow or use green manure that following spring instead, before planting onions late spring?
