I've got these annoying weeds that have sprung up in between my other plants. There are hundreds of these little weeds. Picking each one out is not feasible. But I'm worried that spraying weed killer on such tiny weeds in the beds will damage the other plants nearby, if the liquid weed killer leeches into the soil near the other plants that I want to keep alive. Any tips on a weed killer that won't damage other plants? Thanks in advance.
