Horse tail weed
Could I have help please with my horse tail weed in my garden. I have read that this weed can go as deep as 7foot in the ground and its a very hard weed to get rid of. i made a new vegetable patch in my little garden at the beginning of spring and covered it over to let the soil etc rot down and to use the space to put my pots on while I was having a extension built. The build to far longer then was supposed to which meant I couldn't use my veg bed until now. Last weekend I pulled back the plastic to start and get it ready for winter veg, but I found I have this horse tail weed in over half of the bed. I have looked up weed killers but I'm not sure which one I should use! It seems that this weed is very persistent in coming back, so I know I have to use a very stronge one to hopefully get rid of it. can anybody help me please.
