Check low-lying areas of fields where natural “air drainage” is restricted for frost damage first. To assess seedling viability, split a plant lengthwise through the stem. The growing point should be relatively firm and white or cream colored. Darkening or softening of the growing point indicates a nonviable (dead) plant. Replanting may be warranted if these areas are extensive. Seedlings that have not emerged are somewhat protected by the soil and may be protected from frost except at extremely cold temperatures.
