What do the letters NPK on the fertilizer bag mean?

Those three letters stand for the nutrients nitrogen (N), phosphorus (P), and potassium (K). The numbers you see on the bag let you know the percentage of the N, P, and K that’s in the bag.

Each nutrient is contributing to the health of your grass; up top, down below and inside.

NITROGEN greens up your grass and helps it mature,

PHOSPHOROUS stimulates root growth and helps seeds sprout,

POTASSIUM helps your lawn withstand drought and disease.

Typically, lawn fertilizers will have a high percentage of nitrogen, which makes sense when making your grass green is the dream, am I right?
