A sudden freeze in spring can impact your crops with devastating side effects. Our Agronomists give you some tips to protect your plants from sudden cold snaps.

Early in the growing season, spring frosts are especially harmful. At this growing stage, plants are too fragile to survive unexpected drops in temperature. These episodes of intensely cold weather hazards can cause ice crystals to form in plant cells, which induces cell walls to burst. This makes water unavailable to plant tissues and disrupts the movement of fluids.

Clear evidence of frost damage may be immediately visible or appear later in the growing season. In consequence, leaves can turn slimy and dark, and sometimes fruits will turn yellow or discolored and may drop prematurely.

Tips to protect your crops from sudden cold snaps

When comfortable daytime temperatures provide no sign of incoming frost, it’s best to stay alert during early spring. With these tips, you can protect your crops from frost:

  • Cover and protect vulnerable crops: your best defense against a late frost is a row cover with gauzy white fabric
  • Use heaters and burners spread throughout the field to create a micro-climate that protects from frost
  • Air ventilation is important when possible as creating air movement will prevent frost from forming
  • Keep the soil moist: moist soil holds more heat than dry ones
  • Shower your plants: the night before the frost hits, spray your plants with water
  • Plant nutrition management
