Cloches, those enchanting bell-shaped covers of terra cotta or glass, have long been associated with nurturing early seedlings to maturity or protecting delicate plants throughout unpredictable weather changes. As an essential tool in the gardener’s arsenal, cloches help extend the growing season while providing a haven for plants under their protective dome. In this detailed guide, we will explore what garden cloches are, the materials you can use to craft them, step-by-step instructions for making your own, how to use them effectively, and answers to frequently asked questions.
What Are Garden Cloches?
Definition and Function
A cloche (pronounced “cloash”) is a French word meaning “bell,” which aptly describes its shape. Historically, these structures were designed to protect plants from harsh weather, pests, and chill while allowing sunlight to penetrate. Cloches can be made from various materials, including glass, plastic, or even recycled items, and they come in diverse sizes.
Benefits of Using Garden Cloches
- Temperature Regulation: Cloches create a microclimate, trapping heat and maintaining a warmer environment for plants.
- Frost Protection: They shield young flowers and vegetables from unexpected frosts.
- Pest Barrier: By covering plants, cloches deter pests like slugs and snails.
- Extended Growing Season: Cloches allow for earlier planting in spring and later harvesting in fall.
- Moisture Retention: They can help keep soil moisture consistent, reducing the need for frequent watering.
Materials and Tools You’ll Need
Creating a garden cloche can be as simple or as elaborate as you choose. Below is a list of materials and tools you can consider.
Materials
- Glass Bell Jars: Typically used for food preservation; they come in various sizes.
- Plastic Bottles: Cut plastic bottles can serve as lightweight and effective cloches.
- PVC Pipes and Clear Plastic Sheeting: PVC can form a frame over which plastic sheeting is draped for larger garden areas.
- Wood and Clear Plastic: Decorative wooden frames can hold plastic sheeting or glass in place.
Tools
- Utility Knife or Scissors: For cutting plastic bottles or sheets, if applicable.
- Drill: For creating ventilation holes (important for airflow).
- Ruler: To ensure proportional spacing and dimensions.
Step-by-Step Instructions to Craft Your Cloches
Method 1: Glass Cloches Using Bell Jars
What You Will Need
- Glass bell jars (available at gardening or home improvement stores)
- Sand or gravel (optional)
- A flat surface to work on
Steps
-
Select Your Bell Jar: Choose a size that fits your plants. Tall jars can accommodate larger plants, while smaller jars are excellent for seedlings.
-
Clean the Jar: Make sure your jar is free of dust or residues. A clean surface allows maximum sunlight to penetrate and keeps pests at bay.
-
Choose the Location: Place the jar over the plant you want to protect. Ensure it is on even ground and select a spot that receives adequate sunlight.
-
Secure with Sand (optional): If it’s windy in your area, you can place a small amount of sand or gravel at the base of the jar to hold it steady.
-
Monitor: Regularly check inside the jar. If it gets too hot, you may need to remove it during the warmest parts of the day.
Method 2: Plastic Bottle Cloches
What You Will Need
- Clean, clear plastic bottles
- Scissors or a utility knife
- Optional: duct tape or markers for aesthetics
Steps
-
Prepare the Bottle: Remove any labels, and using scissors or a utility knife, cut the bottle in half or make a cap-like top by cutting off the bottom third.
-
Ventilation Holes: Use the utility knife to poke several holes near the top. This step is essential to allow airflow and prevent moisture buildup.
-
Position: Place the cut bottle over your plant, ensuring it is secure. If necessary, you can bury the edges slightly for added stability.
-
Decorate (optional): Use duct tape or paint to make the bottle a little more aesthetically pleasing to match your garden decor.
-
Adjust: As with the glass cloches, check on your plants regularly, adjusting the coverage based on temperature.
Method 3: PVC Pipe Frames with Plastic Sheeting
What You Will Need
- PVC pipes (¼” to ½” diameter)
- Clear plastic sheeting (6 mil thickness recommended)
- PVC connectors
- Utility knife
- Weights (rocks or bricks)
Steps
-
Design Your Frame: Measurement is crucial here. Avoid too large a frame, as you want it to fit securely over your garden bed.
-
Cut the Pipes: Use a saw or pipe cutter to cut your pipes to length. Standard lengths might range from 3 to 4 feet for the sides and about 5 feet for the top.
-
Assemble the Frame: Connect the pieces using PVC connectors. You can create a rectangular or dome-shaped cover depending on your garden’s requirements.
-
Drape the Plastic: Lay the clear plastic sheeting over the frame, ensuring it covers the entire structure. Use rocks or bricks to secure the edges.
-
Ventilation Considerations: Create openings in the plastic when necessary. You can also leave one side partly open to allow airflow.
Maintenance of PVC Frames
- Regular Damage Checks: Inspect for any rips or tears in the plastic.
- Assessing Temperature: If your plants seem to be overheating, adjust the sheeting or remove it during hot days.
Utilizing Your Cloches Effectively
Placement
- Timing is Key: Place cloches over seeds or tender plants several weeks before the last frost date to enhance germination.
- Space Wisely: Avoid overcrowding plants under cloches; give them space for airflow.
Ventilation
- Open During Heat: On particularly sunny days, lift the cloches for ventilation to prevent overheating.
- Monitor Moisture: If condensation accumulates, raise the cloche slightly to allow moisture to escape.
Seasonal Adjustments
- Spring Use: Use cloches in early spring to protect seedlings.
- Fall Protection: As temperatures drop, use them to prolong the growing season for late harvests.
Frequently Asked Questions (FAQs)
1. Can I use cloches for all types of plants?
Yes! Cloches are versatile and can be used for a variety of plants, including seedlings, young vegetables, and even delicate flowers. However, be mindful of how heat-sensitive certain plants may be; for instance, tropical plants might thrive in cloches but require specific temperature management.
2. How tall should my cloches be?
Height will depend on the plants you’re covering. However, a good rule of thumb is to allow two to three inches above the plant for growth and air circulation. Taller cloches may be necessary for larger plants.
3. What are the best materials for DIY cloches?
Materials depend on availability and aesthetics. Glass cloches look aesthetically pleasing and are durable, while plastic options are lightweight and easier to move. Recycled materials, like plastic bottles, are cost-effective and eco-friendly.
4. How much sunlight do cloches allow in?
Cloches can effectively allow sunlight through. Glass cloches offer maximum transparency, while certain opaque plastics may reduce light levels. As long as your cloche is clear, your plants will receive a good amount of sunlight.
5. Can I leave cloches on during the night?
Yes! Leaving cloches on overnight can provide warmth and frost protection, which is particularly beneficial during cold nights. However, ensure they have ventilation to avoid excessive humidity levels.
6. Do I need to water differently with cloches?
You might, actually. Since cloches reduce evaporation, the soil may stay wetter for longer. Be sure to check the soil moisture regularly. Water slowly to prevent excess moisture buildup.
7. How do I clean glass cloches?
Cleaning glass cloches is simple. Use warm soapy water or a vinegar solution to clean the surface and remove any dirt. Rinse well and ensure it’s dry before placing it back over your plants.
8. Are cloches effective against pests?
Absolutely! Cloches act as physical barriers against many harmful pests such as slugs, snails, and even birds. This protection allows your plants to grow much healthier without the threat of infestation.
Conclusion
Creating your garden cloches is not only an enjoyable craft project but also a practical solution for elevating your gardening game. By investing time in making your own protective structures, you can cultivate a thriving garden that showcases the beauty of nature and enhances your connection with the earth.
From using simple, recycled materials to crafting elaborate cloches, the options are endless. So gear up, let your creativity flow, and enjoy the fruits (and vegetables) of your labor as you implement cloches in your gardening routine. You’ll be rewarded with healthier plants and a fruitful garden that promises to bring joy and abundance for seasons to come. Happy gardening!
