    ....




    looks like wild mustard/charlock....try hand pulling them if it is not too much trouble, or dead heading the flowers before they go to seed- try and prevent them from going to seed as each plant can produce 2,000-4,000 seed:eek: and can remain viable for a long time.

    there are no flowers yet so if i pull them by hand do i need to get the roots too??? some of them are very small so hard enough to get roots and all up
