I recently noticed that my prized rose bushes have been overtaken by a thick layer of weeds, which have grown so dense that they're now competing with the roses for water and nutrients. I've tried to manually remove them, but it seems like they keep coming back. Has anyone else dealt with this issue? What methods have you found most effective in tackling these 'hidden' weeds, and are there any specific products or techniques that you'd recommend for a beginner like me?
