Winter canola (Brassica napus) is a relatively new crop in Vermont. This crop has the potential to be added into a rotation to both promote soil health and yield a crop for oil production. Generally planted in late August or early September, winter canola should produce ample vegetation and root growth prior to plant dormancy (Figure 1). Growers can often fit a canola crop in after harvesting winter grains or other early crops. Regrowth in the spring depends on the harshness of winter conditions, but generally the plants are “greening up” in April, and will enter the rosette stage and begin to leaf out soon afterwards.
