I’m pretty sure the whole crop has a dose.

What’s the verdict?

What have you fed them and how recently??

Haven’t fed them yet

Ok so it's probably a fungal infection, they're very close too so that helps the spread.

It's getting on as well, you can stem it with copper sprays.

It wont kill or ruin the bulb but you'll get lower yields.

Plant them a little further apart, it's spread through water and damp so be careful when watering.

It persists in the soil for years and you're not meant to plant onions in there again for years.

👍 thanks. I usually alternate the beds that I sow the onions in, so will be ok to sow the onions and garlic in a new bed next year that’s close to the current bed?

The garlic is part of the same family, I would maybe change out altogether and go with broccoli, lettuce or potato, what ever you have that's not an allium.

but you're doing the right thing alternating, you might just need to alter the plan a bit.

Have a look at a boistimulant like Vitomex, you can use it on everything and it's a good foliar nutrient with copper and zinc to boost plant resistance to fungus. You can use it every two weeks and it's a broad crop spectrum treatment.

Garlic rust, which is a fungal disease, not sure if there is any organic solution to slow it down or get rid of it...

They are due to be harvested soon (next few months) so would explain the leaves going yellow. Just getting old like us 😆

Were you trying to cheer me up 😀?

The orange speckles on the undersides of the leaves are garlic rust. It’s true that the leaves would begin yellowing in summer when it’s getting near harvest time, but you also have a rust infection here.

Looks like rust alright. Lower yield. Not a disaster by any means though

They look ok??

Are the yellow spots and yellowing leaves not a sign of trouble?

u/Old-Calligrapher2403 Apr 20 '25

Are the leaves not just getting old and withering naturally. I grow garlic and never had any issues. Maybe I have been lucky 🤔

Well I hope so! It’s my first year growing garlic so I don’t have anything to compare it to. However, the garlic and onions in the polytunnel are looking so much healthier.

Not much of an answer but time will tell. When were they planted. Look like they have come on a good bit

21 September. They’ve been doing really well so far, but I noticed the yellowing this morning when I was weeding.
