Title: permanent bed or rotation for onions
Post by: sloworm on June 27, 2009, 14:25
Hi all,
I have been reading the threads about failed onions, mine are rather pathetic specimens - little growth and yellow leaves, i have put this down to lack of experience, planting late and very little rain - (all the watering has to be done with water carried to the plot) !!

My question is would it be worth while dedicating a bed to onions on a permanent basis or continue with my planned 4 year rotation? I have a north facing sloping plot with reasonable soil, when clearing is complete I will have 4 beds 3.5 x 2.5 meters and 3 beds about 2x2 meters, if I had a permenant bed i would use one of the smaller ones.

Thanx again for any advice   :)

don't forget that the champion growers will replace the soil in the beds regularly to prevent the build up of pests and diseases.

I live near the Mammoth Onion place at Forton, Lancashire. Have a look on their website as they use the same beds all the time. Interesting cultivation with a mixture of organic and chemical prep and feed.

Rotate, rotate, rotate! I've just discovered (a bit late) during my first year of growing onions that the previous tennant ALWAYS grew his onions where I've been growing mine.

Might explain the white rot on my garlic  >:(!

Yes, you should always rotate to cut down on pests and diseases. Also always use certified stock.

The question was bound to cause two different views.
I bought the mammoth onion seed last year and read their site and cultivation notes. They do say that they use the same bed(s) again and again.

Equally I know of rotation, actually did rural studies at school as I was in Wilts it was part of life here at that time.

Someone on a section here has asked what do onions take out or put in for them to be able to plan them in to a crop rotation plan. Seems they are a bit neutral, so don't actually fall in too well.

With all that I would say that until the increase of white rot using a dedicated bed was feasible. However as white rot has increased recently, it likes warm and humid weather, it would seem that the days of a dedicated bed are drawing to a close.

Problem is that white rot is a fungus in the soil and last for a period that can be 5 to 18 years, depends on what you read. It can therefore be spread by walking from one bed to another - soil on shoes, or by soil on tools. So rotation will eventually spread it to all beds that you have.
