How do you kill invasive Oxalis?

Oh, and some fertilizer to encourage growth! Not Oxalis, but that was one
of the things we did...mow it down, water and fertilize, wait for it to
start coming up lushly, and cover it with black plastic.

Good luck! Took me 3 years to knock down a yard of pes-caprae with less
brutal methods (pull everything, dig the big resprouts, nuke everything;
repeat weekly vigilance). Of course, that section of the yard was barren
for three years. Now I see a sprig emerging rarely...other parts of the
yard get much less problematical Calla Lily sprouts randomly. Of course it
would have been much less work to bag the whole area for a year.
