Weeds and new mulch
I have several beds with shrubs and mulch that I thoroughly weeded at the start of the summer. All the weeds have come back and I am finally going to buy new mulch (although I can barely afford it). My question is do i rake up all the weeds and old mulch before putting down the new stuff or do I spray weed killer and then put on the new mulch? Or can I avoid the weedkiller altogether? I have kids and a cat that would be difficult to keep out of the garden so I usually don't use weed killer. I have that black underlay in the beds so I would just be raking the much off that. Any advice would be appreciated.
