Which of the following is important when selecting a site for growing in ground nursery stock?

1. Well drained soil

2. Access to a major highway

3. The direction of the prevailing wind

4. The pH level of the soil

The correct answer is: Well drained soil

When selecting a site for growing in-ground nursery stock, well-drained soil is crucial. Proper drainage is essential because excess water can lead to root rot and other fungal diseases that can severely damage or kill nursery plants. Well-drained soil also allows for adequate oxygen exchange in the root zone, promoting healthy root development and overall plant vigor. Though other factors can influence the choice of a nursery site, such as access to transportation and wind direction, they are generally secondary to the health and viability of the plants themselves. The pH level of the soil, while important for nutrient availability, is also considered less fundamental than ensuring that the soil has good drainage. Therefore, prioritizing well-drained soil directly supports the primary goal of fostering healthy nursery stock.
