Gardening enthusiasts often face challenges when it comes to protecting plants from frost during colder seasons. Frost can damage and even kill tender plants, which is why it's important to employ effective methods to shield them. One such technique is using cloches, which provide a simple yet effective solution for safeguarding delicate plants.

What are Cloches?

A cloche is a protective covering used to shield plants from adverse weather conditions, particularly frost. It can be made of different materials such as glass, plastic, or even fabric. Cloches act as miniature greenhouses, creating a microclimate around the plant, trapping heat, and shielding it from frost, wind, or other harmful environmental factors.

Choosing the Right Cloche

When selecting a cloche for your tender plants, there are a few factors to consider:

  • Material: Glass and plastic cloches are excellent choices as they allow sunlight to penetrate while providing superior protection. However, if you prefer a more affordable or lightweight option, fabric cloches can also be effective.
  • Size: The size of the cloche should be suitable for the plant or group of plants you want to protect. It should be large enough to cover the foliage without pressing against it.
  • Ventilation: Ensure that the cloche has proper ventilation to prevent heat and humidity buildup, which can lead to fungal diseases. Look for cloches with adjustable vents or consider propping them up slightly to allow air circulation on warmer days.

Using Cloches for Frost Protection

When frost is forecasted, follow these steps to use cloches for protecting tender plants:

Step 1: Prepare the area

Clear any debris, fallen leaves, or weeds around the plants that will be covered with cloches. This helps prevent pests and diseases and ensures maximum sunlight reaches the plant.

Step 2: Water the plants

Make sure the plants are well-watered before covering them with cloches. Moist soil retains heat better than dry soil, and the extra moisture helps protect the roots from freezing temperatures.

Step 3: Cover the plants

Gently place the cloche over the plant, ensuring it reaches the ground on all sides to create a sealed environment. If using multiple cloches, ensure they are properly spaced to allow air circulation.

Step 4: Secure the cloche

Use stakes or weights to secure the cloche, preventing it from being blown away by wind. Be cautious not to damage the plant by placing stakes away from its fragile foliage.

Step 5: Monitor the cloche

Check the cloche regularly for any signs of excess moisture, condensation, or temperature changes. Adjust ventilation or remove the cloche temporarily on sunny days to prevent overheating.

Benefits of Using Cloches

Using cloches for frost protection offers several advantages:

  • Cost-effective: Cloches are an affordable solution for frost protection, and many can be reused for multiple seasons.
  • Extend growing seasons: By safeguarding plants from frost, cloches allow gardeners to start planting earlier in spring or even continue growing into fall, ultimately extending the growing season.
  • Protection from pests: Cloches can also shield plants from pests such as insects and small animals, giving your tender plants an extra layer of defense.
  • Temperature regulation: Cloches create a warmer microclimate that protects plants from temperature fluctuations, ensuring consistent growth and healthy development.


Using cloches to protect tender plants from frost is a simple yet effective gardening tip. By selecting suitable cloches, properly covering plants, and monitoring their environment, gardeners can safeguard delicate plants and prolong their growing seasons. With the added benefits of cost-effectiveness and the ability to ward off pests, implementing cloches in your garden can be a game-changer for maintaining healthy and thriving plants throughout the year.
