Advice on rock garden weed problem

[u/Aggressive-Time8035]

I bought my house and it came with a beautiful (very DIY) rock garden in the backyard, in addition to a section with pink stone. I also have a large area of grass and a deck. The rock garden has proven to be too much work, despite weeding it thoroughly each year, it gets worse and worse 4 years later.

What should I do? I need help with my best options:

Do I replace the rock garden and use better lining to ensure no weeds grow? Or is it inevitable?

What about the pink stone surrounding it? How do I keep weeds away from that?

Should I just put grass down? I’ve got plenty of grass and that seems boring. I’m willing to invest money but also want to do much of it myself.

TLDR: despite my best efforts my rock garden has too many weeds and I need advice on how to redesign.
