What Causes the ‘Green’ Color of a Lawn?

Grass looks green because it has a special green pigment called chlorophyll. Chlorophyll helps grass make food using sunlight, and that's why lawns stay so lively and green, like magic under your feet!

The Green Magic

When the sun shines on grass, chlorophyll absorbs light and turns it into energy. This process is called photosynthesis. It gives the grass the fuel to grow strong and healthy, keeping it bright and green all year round.
