What’s the best way to rid a planter of weeds when the bed is a layer of decorative rock? Not wise to use a weedwacker on, kneeling and pulling wears the knees out quick.
I guess it depends on what’s in the planter.
Roses, grass, philodendron, and just about everything in between. With roses, of course, the thorns complicate things.
Remove the rocks, put down a layer of landscape fabric, replace rocks.
