Navigating through the seasons as a gardener can sometimes be a challenge, especially when it comes to protecting your crops from low temperatures.

We offer you a comprehensive guide to optimize your vegetable garden throughout the year and identify which vegetables are frost-resistant or not.

Understanding the impact of frost on your plants

Some hardy vegetables, such as spinach, carrots, and turnips, were still harvestable in November in your garden, despite the challenges posed by low temperatures. For example, Milan cabbage is also known for its ability to better withstand the cold due to its sugar content.

However, other water-rich crops that are more sensitive to the cold will not survive negative temperatures, such as tomatoes and peppers. Let’s identify the frost-resistant vegetables first.

Summer vegetables and frost-sensitive vegetables

  • Tomatoes
  • Peppers
  • Zucchini
  • Eggplants
  • Watermelons

These seedlings and crops are called “warm-season” because they require temperatures between 20 and 25°C for a period of several months.

It is essential to avoid frost for these vegetables by growing them in the right season or protecting them from negative and even cold temperatures up to 8/10°C.

Frost-resistant vegetables up to -4°C

  • Fava beans
  • Peas
  • Snow peas


  • Swiss chard (also known as chard in English)

These vegetables can withstand heavy frosts without being extremely damaged. They are suitable for winter gardens in southern regions or near the sea and can be sown directly from February for an early spring harvest.

Frost-resistant vegetables up to -8°C

  • Spinach
  • Milan cabbage
  • Turnips
  • Carrots

These vegetables are considered winter champions. They can endure intense frost and often taste good despite the difficult conditions.

For example, Milan cabbage develops more sugar when faced with heavy frosts.

Managing environmental factors to improve frost resistance

It is essential to note that frost resistance also depends on how the plunge into negative temperatures occurs, the duration of the frost, and ambient humidity levels.

For example, a sudden frost at -2°C with high humidity can be more damaging to certain plants than a constant frost at -5°C. This is because the plants have not had time to acclimate to rapid changes and humidity can amplify the effect of cold on crops.

Growing vegetables in a greenhouse or under a tunnel can also enhance their frost resistance. Chard grown in a greenhouse can recover after being exposed to temperatures as low as -6 to -8°C.

Tips for protecting your crops from frost

  • Use covers or winter protection cloths to protect your plants from negative temperatures.
  • Closely monitor weather conditions and adjust your planting approach accordingly.
  • Invest in a greenhouse or tunnel to provide better protection for your vegetables during the winter months.
  • Sow frost-resistant vegetables in winter to ensure a constant harvest throughout the year.

In conclusion, equipping yourself with knowledge about different types of vegetables and their frost resistance is essential to ensure the success of your vegetable garden.

By adapting your plantings to weather conditions and taking precautions to protect your crops from the cold, you can enjoy a rich and abundant garden throughout the year.
