I have a patch that I want to plant as a natural meadow. But it is full of small green oxalis plants that seem to make hundreds of tiny bulbs or bulbets. It was covered for 6 months over last winter which cut down on the plants but they have come back with a vengeance. It has been hand-weeded several times but just can't get rid of the stuff underground. Is it going to be weed killer? Or I did wonder if takeing off the surface few inches of the soil and discarding it might be the answer.
Any fellow sufferers or solutions welcome.
