I am fascinated to see all the messages about oxalis, as the one we have here is a dreadful weed, multiplies by seed, runners, bulbs, any way at all. I once tried a supposed garden one in a pot and was glad I had done so, as it also multiplied madly, so at least could get rid of it. There was a lot of oxalis weed here in the garden when I came here in 2000. First removed every little tuber, bulb by digging over the garden I wanted to develop, then sprayed with Roundup in a strong mix, and from there on planted plants, hand painting any oxalis which came up (with a very useful little applicator bottle which I saved from the Frend stain remover ;o) which meant no overlap on to anything else.) I have not had anything else affected by the Roundup that way. However, having said that, I see that Dell mentions the effect it has on amphibians, and I never thought of that as I also encourage frogs. What will kill kikuya grass and not affect frogs???
