Nitrogen in fertilizers is like food for your grass. 

This is what you need to get those velvety smooth blades that’ll make you want to kick off your shoes BEFORE you step outside.

Nitrogen also supports the development of chlorophyll, which is the pigment that can make your lawn so green that your neighbors will stoop down to touch it to see if it’s real.

Most lawn fertilizers often have a balanced mix of nutrients, including nitrogen, to ensure proper nourishment for grass and overall lawn health.
