Lawn and Garden Chemicals

Weed and crabgrass killers, plant foods, grass seed and lawn fertilizer.

Lawn and garden chemicals and fertilizer: BioAdvanced and Bonide weed and crabgrass killers in ready-to-use, hose-end and concentrate, Bonide neem oil, Espoma and Arizona’s Best granular plant foods, grass seed and lawn fertilizer. The three numbers on a fertilizer bag are nitrogen, phosphorus and potassium by percentage, and the coverage figure on the front is what you size the bag to, not the weight. Ready-to-use, hose-end and concentrate are the same chemistry at three prices — concentrate is the cheapest per treated area and the easiest to get wrong, ready-to-use is for spot work. Weed killers divide into selective products that spare turf grass and non-selective ones that do not, and that distinction matters more than the brand. Read the label for the target species and the temperature window; most of these fail because they went down too cold, too hot, or before rain.
