The extreme heat can be a real challenge for gardeners, especially when it comes to protecting their plants from the heatwave. High temperatures and burning sun can cause significant damage to leaves, flowers, and plant roots. In this article, we offer several tips to help you protect your garden and your plants from the extreme heat that is expected to hit France.
Proper watering to fight against heat
One of the most effective ways to protect your plants from the heatwave is to provide them with enough water. A regular watering will keep the soil moist and prevent the roots from drying out. Here are some tips for watering your plants properly:
- Water early in the morning or late in the evening: During these times, temperatures are generally cooler, which reduces water evaporation and allows the roots to absorb more moisture.
- Choose a drip irrigation system: This type of watering allows for uniform distribution of water directly on the ground, thus helping the roots absorb the moisture they need without wasting water.

- Use a mulch: Mulching helps to retain soil moisture and reduce evaporation. It is also useful for regulating soil temperature, by preventing the sun from directly heating the roots of plants.
Choosing the right plants to withstand heat
Some plants are better adapted to extreme heat conditions than others. Choosing them can help you create a heatwave-resistant garden:
- Choose native plants: Plants that are native to your area typically have developed a tolerance to local climate conditions, including periods of intense heat.
- Privilege drought-tolerant plants: Some plant varieties are known to withstand dry conditions and require less water. These include lavender, rosemary, or agave.

Tips for protecting your plants from heat
In addition to watering and choosing plants, there are other techniques to protect your plants from the heat:
Create shade for your plants
Providing shade to your plants during the hottest hours of the day can help them better withstand the heat. You can use shade sails, umbrellas, or even temporary structures to shelter your plants from direct sun.

Aerate and decompact the soil
A compacted soil can prevent water from properly infiltrating and limit the roots’ access to the nutrients they need. Regularly aerating and loosening the soil can improve its structure, thus facilitating the absorption of water by the plant roots.
Monitor signs of stress in your plants
During a heatwave, it is crucial to closely monitor your plants to quickly detect signs of heat-related stress. Among these signs are:
- Leaves that wither, even after watering
- A yellow or brown discoloration of the leaves
- The premature fall of flowers and fruits
In case of stress, adjust your watering and provide shade to your plants if necessary.
Protect Potted Plants
The potted plants are particularly vulnerable to heat, as their roots are more exposed to temperature fluctuations. To protect your potted plants from extreme heat:
- Choose suitable containers, avoiding metallic pots that heat up quickly
- Place your pots in shaded locations during the hottest hours of the day
- Maintain adequate humidity by watering regularly and using mulch to conserve water
