Saskatchewan farmers along the U.S. border suffered a hail storm some are calling the worst-ever for June. Early season hail rarely has an impact on canola yield potential. Hailed seedlings usually come back very well.
If hail breaks off both cotyledons or snaps the stem, these plants usually do not survive. But even in these severe cases, while individual plants may die, a whole canola crop is fairly resilient to early season hail when it comes to overall yield potential.
