You could try Pikko Pots... Just remember much of what is gardening is speculation. Some people think you basically have to find the affinite element of the product and "move" the plant's elemental signature as close as you can to the product's signature thus eliminating many of the possibilities you would otherwise get... In practice, there is a good bit of luck involved... Take a look at what Pikko has to say about Wild Onions here:
