Why Every Gardener Needs a Polytunnel
Whether you're a seasoned grower or just starting your gardening journey, a polytunnel is one of the smartest investments you can make for your outdoor space. These versatile structures extend your growing season by months, protect your plants from unpredictable British weather, and can dramatically increase your harvest yields.
What Exactly Is a Polytunnel?
A polytunnel is a tunnel-shaped greenhouse made from a steel or aluminium frame covered with polythene sheeting. Unlike traditional glass greenhouses, polytunnels are more affordable, easier to install, and surprisingly durable. The polythene covering creates a warm, protected microclimate that shields your plants from frost, wind, heavy rain, and pests whilst still allowing essential light through.
The Benefits That Make Polytunnels Worth It
Extend Your Growing Season
With a polytunnel, you can start sowing seeds weeks earlier in spring and keep harvesting well into autumn and winter. Imagine picking fresh tomatoes in October or enjoying homegrown salad leaves in February - that's the polytunnel advantage.
Protect Against Unpredictable Weather
British weather can be brutal on outdoor plants. One late frost, a week of torrential rain, or unexpected hailstorm can devastate months of hard work. Polytunnels provide reliable shelter, giving you peace of mind and healthier plants.
Grow More Variety
Fancy growing Mediterranean vegetables, exotic herbs, or heat-loving crops like peppers and aubergines? A polytunnel creates the warmer conditions these plants crave, opening up a whole new world of growing possibilities.
Increase Your Yields
The controlled environment inside a polytunnel means faster growth, healthier plants, and significantly bigger harvests. Many gardeners report doubling or even tripling their yields compared to outdoor growing.
Save Money on Groceries
Fresh, organic produce from the supermarket isn't cheap. A polytunnel pays for itself surprisingly quickly when you consider the value of the food you'll grow. Plus, nothing beats the taste of homegrown vegetables picked at peak ripeness.
Choosing the Right Polytunnel for Your Space
Size Matters
Polytunnels come in various sizes, from compact 6ft models perfect for small gardens to professional 30ft+ structures for serious growers. Consider what you want to grow and how much space you have. Remember: most gardeners wish they'd gone bigger!
Quality of Materials
Look for polytunnels with galvanised steel frames for rust resistance and UV-stabilised polythene covers that won't degrade quickly in sunlight. Quality materials mean your polytunnel will last for many seasons.
Ventilation Options
Good airflow prevents overheating and reduces disease. Look for polytunnels with doors at both ends and consider models with roll-up sides or roof vents for maximum ventilation control.
What Can You Grow in a Polytunnel?
The short answer? Almost anything! Here are some popular choices:
- Tomatoes - The polytunnel classic, producing abundant crops without blight worries
- Cucumbers and courgettes - Thrive in the warm, humid environment
- Peppers and chillies - Love the extra heat and protection
- Salad leaves - Grow year-round for constant fresh greens
- Herbs - Basil, coriander, and other tender herbs flourish
- Strawberries - Earlier crops and protection from slugs and birds
- Cut flowers - Perfect for extending the flowering season
Top Tips for Polytunnel Success
Location, Location, Location
Position your polytunnel in a sunny spot with good drainage, sheltered from strong winds if possible. Orient it east-west to maximise light exposure throughout the day.
Prepare the Ground
Clear the area of weeds and level the ground before installation. Many gardeners dig out paths and create raised beds inside for better organisation and drainage.
Manage Temperature and Ventilation
On sunny days, polytunnels can get surprisingly hot. Open doors and vents early in the morning during warm weather. Consider installing automatic vent openers for convenience.
Water Wisely
Plants in polytunnels need regular watering as they're sheltered from rain. Installing a simple irrigation system or soaker hoses can save you time and ensure consistent moisture.
Maintain Your Polytunnel
Clean the polythene cover annually to maximise light transmission. Check for tears and repair them promptly. Tighten any loose fittings before winter to withstand strong winds.
