Killing Oxalis

Fri, 02 Oct 2009 14:54:47 PDT
	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.


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.
