Garlic mustard- tried a potful. Not a plat pot full but a kitchen pot full. A frying pan full actually. Ate some last spring an they tasted like rapini. This year they were very bitter. So will try again when they have grown a little more- more like the stage they were last year. Maybe the young leaves, while tender areole bitter than the bigger leaves. Did manage to get rid of a few plants but it looked like there ere hundreds of new seedlings coming up.
