Why do some people grow their own fruit and vegetables?

I think people grow their own produce mainly because it gives them a sense of control over what they eat. You know exactly where your food comes from and how it's grown, which matters a lot these days with all the concerns about pesticides. My neighbor Mrs. Chen, who I mentioned earlier, always says her homegrown tomatoes taste completely different from supermarket ones - sweeter and more flavorful. That said, it's not just about quality - for many, especially older people like her, gardening is a relaxing hobby that connects them with nature. In Shanghai where space is limited, you'll often see people growing herbs on their balconies just for that small daily pleasure.
