At the end of the crop cycle, the seedlings are ready for harvest. Harvesting, or "lifting", is done during the dormant period when the seedlings are in a state of maximum hardiness, or resistance to stress. This time period is known as the "lifting window" and occurs during the late fall, winter, or early spring. In nurseries where the ground freezes, there are two narrow lifting windows: one in the fall, and another in the spring. Because the weather is often too wet in the spring, some nurseries lift a significant portion of their crop in the fall.
