I'm not sure if I've ever posted this, but I have fair success killing Oxalis by spraying with salt and vinegar. One tablespoon salt in a gallon of vinegar. Sprayed on with a little hand sprayer, such as those sold to spray household cleaners, window cleaners, etc. One application will not kill all oxalis plants, but it does kill some, and mostly doesn't hurt other plants. If used in an area which doesn't get much rainfall, the salt buildup would eventually be a problem, but here it isn't. Mulching with several thicknesses of paper or cardboard is also fairly successful, if the oxalis can't crawl out from under the mulch. If it does, just apply more paper/cardboard. Ken Thanks Ken, but mine is anywhere in the garden so have to apply where ever the oxalis is, which means amongst other plants. Which would not be happy with salt and vinegar next to them. However, I do use boiling water and salt on the wandering jew which comes through the fence from the neighbours, pouring it on to their side of the fence (these are non gardeners and don't mind), which works a treat. May use boiling vinegar instead. Wonder how that would go.
