Hi,
please see a picture of my garden bed (lawn on the right side, garden bed above the rocks): https://i.imgur.com/tD7ymtM.jpg
This is not my house just a rental so I can’t go through major changes/investments.
Please how to keep the garden bed free from grass/lawn/weed (grass it’s also growing between the rocks.. very annoying!)
I usually just pull them.. some of them are difficult to get them by the roots this one in particular: https://i.imgur.com/hrYsfzB.jpg
Can I spray something, any better system or idea? Thanks :)
I never sprayed anything because on the right side there’s a regular lawn, and I also have pets roaming in the garden.

PS
I’m based in the South West
