ELI5 : How are grass seeds made?
gpt
Grass produces seed heads, you've probably seen those before. The seeds from those seed heads are harvested, dried and sold. If you put them into soil and water them, they sprout and grow into new grass. People who don't want those on their lawn make sure the conditions for the grass stays constant, it receives enough water and is mowed regularly (so seed heads can't develop).
