What Are Low Tunnels and Why Use Them?
Low tunnels are key for efficient gardening, perfect for allotments. They protect crops from bad weather and improve their growth. They raise air and soil temperatures, extending the growing season by four to six weeks. This is great for gardeners wanting to get more from their plots all year.
Benefits of Low Tunnels for Allotment Gardening
Using low tunnels can change your gardening. Here are some main benefits:
- Temperature Regulation: They warm the soil and air, perfect for seeds and plants.
- Protection: Low tunnels protect plants from wind, hail, and heavy rain, keeping them healthy.
- Water Efficiency: They keep moisture in, vital for crops in dry times.
- Extended Growing Season: They let gardeners plant earlier in spring and harvest later in autumn.
Difference Between Low Tunnels and Polytunnels
Low tunnels and polytunnels differ in several ways. Low tunnels are simpler to set up and can be moved. They’re ideal for small allotments where space is tight. On the other hand, polytunnels are bigger, last longer, and can grow more, but cost more upfront. So, low tunnels are good for quick, flexible use, while polytunnels are better for long-term growing.
Choosing the Right Materials for Your Low Tunnel
Starting a low tunnel project means picking the right materials is key. The right stuff makes your tunnel last longer and helps your plants grow better. Knowing your options is essential for great results.
Types of Covering Materials
Horticultural fleece is a popular choice. It lets in 70-85% of light and keeps things warm. It’s great for cold nights and bad weather.
High-quality polythene covers are also good. They last a long time and work well in all weather.
While cheap options might look good, spending on quality is better. Good covers protect your plants and help them grow well.
Recommended Hoops and Frames
I suggest using PVC pipes or galvanised steel hoops for frames. They’re strong and last long. Hoops should be 9 or 10-gauge stainless steel, about 2 metres long. Keep them 1.5 metres apart for stability.
Don’t forget heavy boards or bricks to keep the fabric tight. The right hoops and frames make your tunnel strong and productive.
DIY Low Tunnel for a UK Allotment
Building a low tunnel can extend my growing season and boost crop yields. This guide helps me build a low tunnel for my UK allotment. It’s a practical way to add warmth and protection for my plants.
Step-by-Step Construction Guide
I start by deciding on the tunnel’s size and preparing the ground. It’s important to use strong materials like PVC or galvanised steel for the hoops. This makes the tunnel stable and easy to build, taking just a few hours with a friend’s help.
- Mark the area for the low tunnel.
- Assemble the hoops to the required dimensions.
- Secure the hoops into the ground and ensure stability.
- Cover the structure with a horticultural fleece, ensuring it extends beyond the hoops.
- Secure the edges by burying them or using bricks and boards.
Tools Needed for the Project
For building a low tunnel, I need specific tools. A basic toolkit is enough to get the job done:
- Shovel for digging and preparing the ground.
- Mallet for driving the hoops into the soil.
- Clamps to secure the covering material.
- Measuring tape for ensuring accurate dimensions.
- Tree stakes for additional anchoring at the corners.
It’s key to keep the covering material tight for better durability and crop protection. By following these steps, I can create a successful vegetable garden tunnel and make the most of my allotment.
Tools | Purpose |
---|---|
Shovel | To dig the ground and prepare for hoop installation. |
Mallet | To securely insert the hoops into the ground. |
Clamps | To attach the covering to the structure securely. |
Measuring Tape | To ensure accurate measurements and proper spacing. |
Tree Stakes | To anchor the structure and provide additional strength. |
Setting Up Your Low Tunnel: A Practical Approach
Choosing the right spot for your low tunnel is key to its success. It should get plenty of sunlight but be safe from strong winds. Knowing how to keep it stable means your garden can thrive, even when the weather is tough.
Tips for Placement on Your Allotment
Look for a spot that gets sunlight most of the day. This helps your plants grow strong. Also, pick a place that’s not too windy to keep your plants safe. Here are some tips:
- Choose a flat area to ensure even sunlight.
- Avoid spots where frost can collect.
- Make sure you can easily get to the beds for upkeep and picking.
Securing Your Low Tunnel Against the Elements
Keeping your low tunnel safe from the weather is very important. Make sure each hoop is well anchored to the ground. Adding weights, like bricks, can help it stand up to strong winds. Check it after storms to keep it in top shape. Here are some ways to do it:
- Make sure the hoops are well buried in the ground.
- Use side curtains or extra covers on windy days.
- Check it every couple of weeks to keep it in good condition.
Placement Tips | Securing Methods |
---|---|
Maximise sunlight exposure | Anchor each hoop securely |
Avoid low frost-prone areas | Add weights at edges |
Prioritise easy access for maintenance | Use side curtains on windy days |
Regularly assess ground conditions | Check structure every couple of weeks |
Low Tunnel Maintenance for Optimal Performance
To keep your low tunnel working well, regular care is key. Spending time on maintenance boosts your gardening joy. It helps plants grow strong and keeps problems away. Here are some important steps to follow.
Regular Checks and Adjustments
It’s important to check your low tunnel often, more so when it’s windy. I make sure it’s strong and can handle the wind. Using clothespins keeps the cover in place, protecting plants from the wind.
This method is great for keeping your garden safe from bad weather. It’s a useful tip for any allotment gardener.
Managing Weeds and Pests Under the Tunnel
Weeds love the warm, sheltered spot under low tunnels. I set aside time to weed regularly, using sharp tools to control them. This keeps my plants healthy and stops them from fighting for food.
Low tunnels also help fight pests by blocking harmful insects. This means I don’t need to use harmful chemicals. A clean, pest-free area leads to better crops.
Vegetables to Grow in Low Tunnels
Growing vegetables in low tunnels is rewarding. These tunnels protect plants and help them grow better. They also let us harvest more vegetables throughout the year.
Cool-Season Crop Recommendations
Here are some top cool-season crops for low tunnels:
- Lettuce: Plant in April and enjoy harvesting by June.
- Broccoli: Sowing from April to June leads to a late autumn harvest.
- Carrots: Early planting from April to July allows for harvesting from July to October.
- Cabbage: Plant in July and August for a spring harvest, approximately 4 to 6 months later.
- Spinach: Early module sowing can provide an abundant crop.
Extending the Growing Season with Low Tunnels
Low tunnels protect crops and increase yields. They create a warm space for early planting or late-season growth. For example, early potatoes can be sown in February.
Peppers and courgettes do well after the last frost, usually in early May. Low tunnels extend the growing season. They offer warmer conditions, preventing frost damage and pests. This means earlier harvests and more productivity.
Homemade Hoop House Instructions
Starting a homemade hoop house project is exciting. It’s key to know the differences between garden structures. Low tunnels and hoop houses have unique designs for different garden needs.
Differentiating Between Low Tunnels and Hoop Houses
Hoop houses and low tunnels differ in design and use. Hoop houses use 25mm polypipe hoops for strength. They can handle tough weather and support big crops.
Low tunnels are simpler and shallower. They’re easy to move and set up. This makes them great for extending the growing season on the go.
Building a hoop house creates a warm, safe space for plants. Using insect netting instead of plastic can help plants grow better. It’s important to use rustproof staples and space pipes 400mm apart.
Setting up a hoop house is affordable and easy. It’s perfect for making the most of your garden space. With some planning and basic materials, you can build a great hoop house.
Allotment Gardening Tips for Beginners
Starting an allotment garden is both thrilling and daunting. Beginners can benefit from several tips, from making the most of space to understanding soil and weather. These strategies will help you enjoy a successful gardening journey.
Maximising Your Space with Low Tunnels
Low tunnels can change how you use your allotment space. By planning well, you can grow taller plants alongside shorter ones. This space maximisation in gardening is key when space is limited. It lets you grow more crops in the same area, leading to better yields.
By focusing on smaller plants, you can manage your resources better. You can also watch how plants grow over the season.
Understanding Your Soil and Environment
Knowing your soil quality is key for growing plants well. Testing your soil can show what it’s made of, which affects what you can grow. The best time to clear your allotment is in autumn or winter.
This makes it easier to manage your plot. It also means you won’t have to compete with plants in the spring. Adding organic matter, like homemade compost, makes the soil healthier and better at draining water. This is great for heavy clay soils.
Understanding these factors is essential for growing healthy crops. It helps you get the best results from your garden.

Budget-Friendly Alternatives to Commercial Tunnels
Looking for ways to save money in gardening can lead to creative ideas. One great option is using reclaimed materials for gardening. This method saves money and helps the environment.
Using Reclaimed Materials for Your Low Tunnel
Adding reclaimed materials to your low tunnel makes it both useful and green. It’s a way to be creative while staying within your budget. Here are some materials you can use:
- PVC pipes for the frame
- Old wooden pallets as side walls
- Used polythene for covering
- Wire mesh for added support
These materials cut down the cost of building a traditional tunnel. The strong nature of these items, combined with good design, makes a durable space for plants.
Using reclaimed materials also makes your garden eco-friendly. It reduces waste going to landfills. So, by choosing low tunnels made from recycled materials, you save money and help the planet.
