Patty, this is not the yellow flowered variety we have here, but ours is
a plague as you describe. When I moved here 10 years ago, it truly was
a plague too. I don't know if you have Frend in an applicator bottle,
but I mixed a really strong solution of Roundup (glycophosphate or
whatever it is called) and put it in one of those bottles , than hand
wiped each leaf of Oxalis. Very rarely now does one appear, I suppose
seeded from the neighbours. It took time and patience, but has paid off.

As you say, digging it up was impossible. Was told by friends I would
never get rid of it!

Once it gets going , it is almost impossible to get rid of. It makes a
tremendous amount of seed and it is nearly impossible to get all of them
when you are tryng to dig up a clump to do away with!
If someone knows of a product that will kill them, please share with me.
