Sounds like galium aparine, also known as goose grass, very invasive but easy to pull out, but use gloves as the stems can soon cut your hands. derekm

Also called sweethearts. Pull it out and throw it at someone you fancy!!

And I know it as cleavers or goose grass. We used to wear green wigs of it when we were children or see how much of it you could stick on a sibling's back without their noticing.

Just keep pulling it out, but you need to be aware that it tends to break off just above soil level, leaving the roots in the ground for fast regrowth. It's better to try to get the roots out as well, if you can.

And try to get it out before the little sticky seed heads form, or there will be masses more of it next year... which is a job I must really get around to Tomorrow!

haha we call it "sticky willy" in our house !

Lol!Not heard that one before.
If you keep hens, they love it !

I did get round to it - mostly gone now!
