As the winter months approach, gardeners often find themselves wondering how to protect their plants from the harsh, cold weather. One popular solution is the use of cloches, which are essentially protective covers that shield plants from the elements. But do cloches keep plants warm? In this article, we’ll delve into the world of cloches, exploring their history, functionality, and effectiveness in keeping plants warm and thriving.
Introduction to Cloches
Cloches have been used in gardening for centuries, with the first recorded use dating back to 17th-century France. The word “cloche” is French for “bell,” which describes the bell-shaped design of these protective covers. Initially, cloches were made from glass, but modern versions can be found in a variety of materials, including plastic, metal, and fabric. Their primary purpose is to create a microclimate around the plant, protecting it from frost, wind, and extreme temperatures.
How Cloches Work
Cloches work by trapping a layer of warm air around the plant, creating a greenhouse-like effect. As the sun heats the air inside the cloche, it warms the plant and the surrounding soil. This warmth is then retained, even after the sun sets, providing the plant with a stable and cozy environment. Additionally, cloches can be used to prevent moisture loss, reducing the need for frequent watering and minimizing the risk of root rot.
Benefits of Using Cloches
There are several benefits to using cloches in your garden, including:
– Protection from frost and extreme temperatures

What are cloches and how do they work?
Cloches are individual plant coverings made of transparent or translucent materials such as glass, plastic, or polyethylene. They work by trapping a layer of warm air next to the plant, protecting it from cold temperatures, wind, and frost. This process is known as the “greenhouse effect,” where the sun’s rays enter the cloche and warm the air inside, which is then retained by the cloche, keeping the plant warm. The cloche also helps to maintain a humid microclimate, reducing moisture loss and preventing the plant from drying out.
The effectiveness of cloches in keeping plants warm depends on various factors, including the type of material used, the size and shape of the cloche, and the amount of sunlight it receives. Cloches can be used to extend the growing season, allowing gardeners to plant earlier in the spring and later in the fall. They are particularly useful for protecting sensitive or young plants from extreme weather conditions, such as frost, hail, or strong winds. By creating a warm and cozy environment, cloches provide plants with the optimal conditions to grow and thrive, making them a valuable tool for gardeners of all levels.
Do cloches really keep plants warm?
Yes, cloches can keep plants warm by trapping warm air and protecting them from cold temperatures. The temperature inside a cloche can be significantly higher than the outside temperature, sometimes by as much as 10-15°F (5-8°C). This warming effect is especially noticeable during the night, when the temperature often drops to its lowest point. By retaining the warmth generated during the day, cloches help to keep plants from experiencing extreme temperature fluctuations, which can be detrimental to their growth and development.
The warming effect of cloches is not limited to cold temperatures; they can also help to protect plants from heat stress during extremely hot days. By providing shade and maintaining a cooler microclimate, cloches can prevent plants from overheating and reduce the risk of scorching or sunburn. Additionally, cloches can help to regulate soil temperature, which is essential for healthy root growth and nutrient uptake. By keeping the soil warm, cloches promote root development, allowing plants to absorb essential nutrients and water more efficiently, leading to healthier and more productive plants.
What types of plants benefit from cloches?
A wide range of plants can benefit from cloches, including sensitive or young plants, such as seedlings, cuttings, and newly transplanted specimens. Cloches are particularly useful for protecting plants that are vulnerable to frost, such as tender perennials, shrubs, and trees.
