Creeping Oxalis In Your Lawn

Have a look at the very hard to notice Creeping Oxalis (both green and purple varieties).
For the fussy lawn lover this is a pain in the neck.
Best treated with Amgrows Bin Die or Barmac’s Javelin (or Bayer’s Spearhead).
To help the chemical bond with the weed use a surfactant (or detergent in the herbicide mix as a back stop).
