Solved Can you identify this weed ?

Have a weed infestation.

Every time it rains about 2 weeks late there is this thick mat of weed.
Hoeing seems to have no effect - it regrows.

Hand extraction takes Hours - they have long white thread like roots, and I have noticed a great many of them have grown what I can best describe as a translucent carrot root.

What is this weed, and where does it come from.

 

oxalis

 

I think wood sorrel, an Oxalis, see here:https://garden.org/plants/photo/443691/

 

We have Oxalis pes-caprae here. It is light a nightmare, air borne.

 

A real PITA, weedkiller is the only option I have found and even then it can come back.

 

Apparently all parts are edible.

 

welcome to come & eat mine

 

So the fact not seen it before, means its airborne from somewhere ...... incredible there are thousands of them.
I'm not a far of pesticides .... but is there something specific that will kill this staff and not hurt the vegetables that are growing ?
3 large sackfulls pulled out again yesterday, they certainly grow faster than any of my veg.

 

Yep that's it

 

Close but mine has different flowers - and matches what NIGELJ posted Pink Wood Sorrel (Oxalis debilis) or possibly Oxalis Latifolia ... can't tell the difference.

Is there any pesticide that is Veg safe I can use ?

 

Not that one as does not have yellow flowers ... I think it Oxalis Oxalis Latifolia or Oxalis Debilis, either way I don't want it

 

Hoeing or pulling by hand are better than weedkilers. The small, yellow flowered one is a serious PITA here, especially in my pots.
