General recommendations frost

What to do when ground frost is forecast

  • In certain sectors, such as agriculture and the construction industry, it is important to know in advance if there is a likelihood of frost.

    For this reason, MeteoSwiss provides a frost warning when there is a likelihood of frost. There are various precautions that can be taken to minimise frost damage.

    See potential impact and hazard categories of ground frost.

What to do when there is ground frost

  • Ground frost can cause damage to plants and crops, and disrupt construction work. The major factors contributing to the formation of frost are the minimum temperature on a given night, the amount of cloud cover, and wind.

    Various precautions can be taken to limit frost damage:

  • Cover plants with a protective layer; place pot plants that are particularly susceptible to frost damage against a house wall.

  • Protect building sites and any construction materials on the site against frost damage.

What to do after ground frost has occurred

  • There are certain measures that can be taken to tend frost-damaged plants, and to ensure that they are betterprepared for frost in future.

    Further information on these measures is available on the Agroscope .
