I have looked and looked but get conflicting advise or generalisations, so - what fertiliser for onion?  I have chicken pellets and blood, bone and fish at the moment.  Will any of them do or do I need to get something else.  Please can you be specific as you are dealing with someone who understands things like "get xyz" if you say " get a nitrogen rich fertiliser" I won't know which one to get without going to the garden centre and reading all the packs, which I don't have time for :blink:

Perhaps the generalisations were about using a general fertiliser?   

Both of those you already have are general fertilisers - some people swear by extra potash but like most plants onions are happy as long as they've got a bit of everything.

I tend to use chicken manure pellets & although the pictures below are of my kelsae in 2011 I think it does just fine

Haha the photo's don't do them justice the pic with the 4 on shows the onions that I entered into the local show & won 2nd place,can't remember the weights but over 3lbs I think.

I find that a watering in of sulphate of potash gives a good strong root system and seems to reduce the chances of rust etc.

I daresay others have other routes to success of course

Ah Onions, apart from Calabrese looking like a flower, I just can't get my onions to any decent size..

Potash I think I'll try in the watering can.

If I dont get any decent ones this year I'll prob give up on them..
