Gardening can be a rewarding experience, but it also requires careful attention and protection to ensure your plants thrive. Sudden temperature drops, especially during the spring and fall seasons, can be detrimental to delicate plants. However, you can safeguard your garden by using cloches, which create a protective environment for your plants. In this article, we will explain what cloches are and how they can be effectively utilized to shield your plants from sudden temperature fluctuations.

What are Cloches?

Cloches are protective coverings used to create a small, controlled microclimate around plants. They can be made of various materials such as glass, plastic, or even cloth. Cloches are typically dome-shaped and cover individual plants or small sections of the garden bed. The primary purpose of cloches is to provide shelter from adverse weather conditions such as frost, wind, or sudden drops in temperature.

How Do Cloches Protect Plants?

Cloches serve as a barrier against outside elements and promote a favorable environment for plant growth. When used to protect plants from temperature drops, they offer the following benefits:

  • Temperature Regulation: Cloches retain heat from sunlight during the day and release it back to the plants at night, creating a warmer and more stable environment.
  • Prevention of Frost Damage: Cloches act as a shield, preventing frost from settling on plants and causing damage.
  • Wind Protection: Cloches protect plants from strong winds that can dehydrate or break fragile stems.
  • Increased Humidity: The enclosed space under a cloche preserves moisture, creating a more humid microclimate that some plants prefer.
  • Pest and Animal Deterrence: Cloches can also help keep pests, insects, and small animals away from your plants, safeguarding them from potential damage.

Types of Cloches

There are various types of cloches available, and selecting the right one depends on your gardening needs and the specific plants you want to protect. Some commonly used cloches include:

  • Glass Cloches: Glass cloches create a greenhouse-like effect, offering excellent insulation and maximum light transmission. They can be substantial and fragile, so handle with care.
  • Plastic Cloches: Plastic cloches are lightweight, cost-effective, and easy to handle. They are available in various shapes and sizes, providing versatility for different plant types.
  • Cloche Tunnels: Cloche tunnels are elongated structures that can cover rows of plants. They are often made of plastic or fabric and offer protection on a larger scale.
  • Cold Frames: Cold frames are like permanent cloches made from glass or plastic. They are larger structures that can cover entire beds or rows, providing extended protection.

Consider your gardening requirements and the weather conditions in your area to determine the most suitable type of cloche for your plants.

Using Cloches Effectively

To optimize the benefits of cloches and protect your plants from sudden temperature drops, follow these guidelines:

  1. Monitor Weather Forecasts: Stay informed of upcoming temperature drops or frost warnings, so you can prepare your plants in advance.
  2. Timing is Key: Place cloches over plants before temperatures dip, ideally in the late afternoon or evening.
  3. Air Circulation: Ensure there is sufficient airflow within the cloche during the day to prevent excess heat buildup.
  4. Watering: Water plants thoroughly before covering them with cloches, as moist soil retains heat better than dry soil.
  5. Ventilate: On warmer days, prop open or partially remove the cloche during the day to avoid overheating your plants.
  6. Remove During Suitable Weather: Once the risk of sudden temperature drops has passed, remove the cloches to avoid creating unfavorable conditions for your plants.


Cloches are an effective tool for protecting plants from sudden temperature drops, frost, wind, and other adverse weather conditions. By using cloches, you can create a sheltered microclimate that allows your plants to thrive and avoid unnecessary stress. Remember to select the appropriate type of cloche for your plants and follow the guidelines mentioned to achieve the best results. So, when the temperature drops unexpectedly, don't fret – just reach for your trusted cloches!
