Brown Garlic Leaves

If it was wind damage i would expect to see the whole row affected. I would carefully dig up one plant to make sure all is well with the bulb. Any sign's of mildew or a white fluffy growth on the bulb spell's problem's.

I put these in in September and one of the varieties was Early Solent Wight, I was rather hoping it was just being very early

  somehow I think you are being a little optimistic there

As for the yellow leaves, I'm inclined to think it is not a soil pathogen - it's been so cold this winter/spring and they (bacteria or fungus/mould) usually like mild conditions before doing damage.  Although it may just be a few showing signs, is it possible those are in a slightly different environment to the others?  The photo shows a structure to the left so that may be doing something to the wind/cold/snow drifts/lack of water .... ?

Pdblake - The answer to your question in two words... the weather.

All the garlic I've seen on our site is the same - even mine..

I do hope so. I'll lift one at the weekend though, just to be safe

 You are not on your own...I have brown / yellow tipped leaves as well. I think it is the weather. Now the wind has moved to the south and temperatures have risen I am expecting a growth spurt any time soon.

Thanks all, that's very reassuring. This is the first time I've grown garlic on the plot. It's normally in the much more sheltered back garden.
