Applying Fertilizer Over Mulch

The best steps in combining fertilizer and mulch


Can a weed control or fertilizer product be applied on top of mulch, or must I first remove the medium bark mulch to receive any benefit?

Roger says: I know of at least one weed control often combined with fertilizer that can be applied over mulch. But the majority of these products require application before the mulch goes down. Talk to your local garden center on which weed control would best suit your situation.
