Frost has been reported regularly and the forecast for the coming days remains cool with over-night frost in many areas. If canola has emerged, remember a proper assessment of frost damage can’t be made for several days, until it can be determined if new growth is appearing on damaged plants. One benefit of the growing conditions this spring is that they have been conducive to acclimatizing canola seedlings. These cool growing conditions may help the tiny seedlings tolerate light frosts.
