Hi Asier. Txomin Herb, Lekeit-Belarra, Bering-Herb, Barrabas-Belarra, Barrabas-Belarra, Potro Herb... How many names does this herb have? All of them indicate that the herb is bad or annoying. Its scientific name is Oxalis latifolia. It is very difficult to remove it from the orchard, I would say that it is impossible to completely remove it. With chemical herbicides you will completely contaminate the earth and for a long time you will not be able to eat anything that has occurred in it. The Rotabatorra is your best friend, cuts and extends the underground bulbs you mention. I think we have to ignore the barabbas and put higher plants in places where there are many plants and use clean soil to put the little ones or to make seeds.
