Why are bedding plant seeds typically sown in rows?

Sowing bedding plant seeds in rows is primarily done to minimize disease spread. When seeds are spaced out in rows, it allows for better airflow between the plants, which can help reduce humidity levels in the growing environment. High humidity is often conducive to the spread of fungal diseases and other pathogens. By providing adequate spacing, the likelihood of plants coming into contact with each other and transmitting diseases can be significantly lowered.

Additionally, sowing in rows makes it easier to monitor each plant's health, as well as to identify and isolate any plants that may show signs of disease early on. This practice not only helps in maintaining overall plant health but also contributes to a successful and productive growing environment.
