Hi all,
I just bought a new place and am working to create a garden. The previous owners planted a bed of myrtle that is well established but unfortunately it is full of weeds and long blades of grass.
I spent hours weeding it last weekend and it looks as bad as it did before I started.
Any suggestions on how to deal with this? I'd hate to pull it all out since the flowers are so pretty in the spring, but it really looks awful. ( see picture )

Thanks for your help!
