Given that the weather does not always cooperate, it is important to be aware of the implications of variation in planting date and how to adapt accordingly. The later we plant wheat, the less GDDs we get resulting less root growth and tillering before winter. Results from seeding-date trials at five locations across Ontario confirmed the concept of a 2-wk optimum seeding period (OSP) for winter wheat. As a result, later than the optimum date, the seeding rate should be increased Why is planting your winter wheat at the optimum time for your As we saw in 2019, if winter wheat is planted late and if conditions are not fit, there is a greater risk of winter survival issues.
