Does anyone know how to eliminate Oxalis obtusa? I brought it into my present bulb house by accident, presumably as dormant bulbs (or whatever their tiny storage organs are properly called) that had got into the tunics of bulbs I brought deliberately, or that were clinging to some pots. All subsequent attempts to control it have failed, even replacing quite a bit of the plunge material where it's growing. I was just weeding out the crowns and wondered if there's a point in its growth cycle when the dormant bulbs have produced growth, but when new bulbs are not present. There are white stolons dropping from the crowns, and perhaps these will produce next season's storage structures. Can anyone advise on this? Although attractive in flower, it's a real pest. Fortunately it's not winter-hardy outdoors here. Don't ever let it loose in a warmer garden!
