A polytunnel, also known as a hoop house or high tunnel, is a versatile structure that can extend the growing season and provide a controlled environment for plants. It offers protection from harsh weather conditions such as frost, wind, and excessive heat, allowing gardeners to cultivate a wide range of crops.

1. Leafy Greens

Leafy greens are ideal for growing in a polytunnel because they thrive in the cool and sheltered environment it provides. Some popular options include:

  • Lettuce: Varieties such as romaine, butterhead, and loose-leaf lettuce are all well-suited for polytunnel cultivation.
  • Spinach: This nutrient-rich green vegetable grows well in the protected environment of a polytunnel.
  • Kale: Known for its hardiness, kale is an excellent choice for year-round cultivation in a polytunnel.
  • Swiss chard: With its vibrant colors and mild flavor, Swiss chard is a versatile and nutritious addition to any polytunnel garden.

2. Tomatoes

Tomatoes are a popular crop for polytunnel gardening due to their high value and the extended growing season they can enjoy in a controlled environment. Varieties such as cherry tomatoes, beefsteak tomatoes, and heirloom tomatoes all thrive in polytunnel conditions.

When growing tomatoes in a polytunnel, it is important to provide support for the plants as they grow. This can be done using stakes, trellises, or cages to prevent the plants from sprawling and to maximize space utilization.

3. Peppers

Peppers, both sweet and hot varieties, are well-suited for polytunnel cultivation. The warm and protected environment of a polytunnel allows peppers to thrive and produce an abundant harvest.

Popular pepper varieties that can be grown in a polytunnel include bell peppers, jalapenos, habaneros, and banana peppers. These crops require a longer growing season than many other vegetables, making a polytunnel an ideal solution for gardeners in regions with shorter summers.

4. Herbs

Many herbs can be successfully grown in a polytunnel, benefiting from the protection it provides against extreme weather conditions. Some popular herbs for polytunnel cultivation include:

  • Basil: This fragrant herb thrives in warm and sheltered conditions, making it an excellent choice for a polytunnel.
  • Parsley: With its rich flavor and versatility, parsley is a staple herb that can be grown year-round in a polytunnel.
  • Coriander: Also known as cilantro, coriander is a popular herb that prefers cooler temperatures, making it an ideal candidate for polytunnel cultivation.
  • Thyme: This aromatic herb is well-suited for polytunnel gardening, as it requires a sheltered environment to thrive.

5. Root Vegetables

While some root vegetables may require more space than others, there are several varieties that can be successfully grown in a polytunnel. These include:

  • Carrots: Carrots can be grown in a polytunnel all year round, ensuring a continuous harvest.
  • Radishes: These fast-growing root vegetables are well-suited for polytunnel cultivation, as they prefer cooler temperatures.
  • Beets: Beets are a versatile root vegetable that can be grown in a polytunnel, providing a steady supply of nutritious and colorful produce.


A polytunnel is a valuable asset for any gardener, providing a controlled environment that extends the growing season and protects crops from adverse weather conditions. By choosing the right crops for a polytunnel, such as leafy greens, tomatoes, peppers, herbs, and root vegetables, gardeners can maximize their harvest and enjoy a wide variety of fresh produce year-round.

Whether you are a small-scale gardener or a commercial grower, a polytunnel offers numerous opportunities for successful cultivation. Experimenting with different crops and techniques can help you discover the best combination for your specific needs and preferences. So go ahead, get creative, and start growing in your polytunnel!
