Step-by-step explanation:
The first person to plant seeds in a vacant lot can be traced back to ancient times when hunter-gatherers began favoring certain plants and weeding around them to help them grow larger and make them easier to reach. They also discovered that seeds dropped into rubbish heaps sprouted into new plants.
As a result, people started planting or transplanting their favorite plants closer to home so they wouldn't have to go far to find food. This practice, known as horticulture or part-time farming, might have begun before ancient humans began to spread from the Black Sea area to Europe and Asia.
