Why does the grass spread when we cut it?

When grass is cut, it stimulates the plant's growth response, encouraging it to spread and proliferate. Cutting the grass removes the tips of the blades, which are responsible for photosynthesis; this prompts the plant to send out new shoots and roots to compensate. Additionally, the open space allows for better light penetration and air circulation, promoting further growth and expansion. As a result, grass can become denser and spread more effectively after being mowed.
