Anyone know this plant/weed?
Hi, I'm new to gardening and recently bought my first house and attempting to transform my garden which I'm absolutely loving. I have a question for all the more experienced gardeners out there, I have a plant that keeps popping up everywhere, it's impossible to pull up as it has these bulb/kernel like bits on its roots. It spreads proflifically and only goes away if you pull out these brown "bulbs". Any ideas what this is and how I can get rid or it? Some areas are in places I cannot dig up the root system so I'm reall stuck. Please see my picture of the plant.
Thank you all
