When inspecting nursery plant shipments, what should be examined for alongside pests and diseases?

When inspecting nursery plant shipments, it's crucial to examine weeds in addition to pests and diseases. Weeds can be a major threat to any horticultural operation as they can harbor pests, compete with desired plants for nutrients, water, and light, and potentially introduce diseases. By thoroughly checking for weeds, you ensure that the plants being received are not only healthy but also free from unwanted competition that could affect their growth and overall health once planted.

The other options, while important in various contexts of plant health and horticulture, do not directly relate to the immediate concerns during the inspection of nursery shipments. Weather conditions can influence plant growth and health but are not typically assessed at the time of shipment inspection. Soil quality is more relevant at the planting site or nursery than in a shipment. Water content is essential for plant health, but it is not a primary focus during shipment inspections, where visible pests, diseases, and weeds are more critical to ensure the plants' immediate viability and health upon arrival.
