20 Jun 23, Sue (New Zealand - temperate climate): My onions got a rusty fungus on the last year how do I guard against this happening again. I grew the multiplying onions found them in the garden centre as Welsh Onions. They were great until they developed the fungus.

24 Jun 23, jim (New Zealand - temperate climate): Copper copper copper I had same problem last year onions,garlic and leeks sometimes gardening is a pain but I still do it ??? Remember to use a sticker "sprayfix" by yates is one but most garden chemical people do similar it helps to break down the surface tension so the spray does not just run off do it before it appears and repeat it several times during the season only problem with it raining constantly it's hard to do right now. P.S. my mum used to grow welsh onions in the UK when I was a boy never saw enything like rust ?
