If you are considering building a polytunnel in your backyard, you may be wondering what types of plants do best in these structures. Luckily, there are some great options out there. Here are a few ideas for you to consider. A polytunnel allows you to control the growing environment. You can use equipment and tools to control the temperature and humidity, which will benefit your plants. Also, a polytunnel will help you keep beneficial insects such as ladybugs, aphid midges, honeybees, and braconid wasps in the area. Other helpful insects that love to live in polytunnels include tachinid flies and soldier beetles.
Plants that do well in a polytunnel
The polytunnel is an ideal place to grow a range of plants, including herbs. These plants can thrive in this environment, providing them with the extra protection and warmth they need to thrive. They will produce flowers, fruit and vegetables throughout the growing season, and can even be grown year round.
Some crops do particularly well in polytunnels, including peppers and potatoes. These plants need to be protected from high temperatures and extreme wind, so a polytunnel will protect them from these adverse conditions. In addition, lettuce is a prime target for pests, so growing lettuce in a polytunnel can ensure that the crop survives both the cold and the heat.
A polytunnel will keep plants warm, and the temperatures within will vary according to the time of year. A polytunnel will usually be about thirty degrees warm during winter and thirty degrees in the summer. The climate inside depends on the type of polythene used and the outside temperature, so if the weather is too hot or too cold, you can adjust the polytunnel to reduce the temperature inside.
If you’re not sure which vegetables will thrive in a polytunnel, you can experiment with some autumn crops. If your crops are doing well in autumn, they should do fine in the polytunnel through the winter. A polytunnel can even be used to grow garlic, which is one of the few vegetables that does well in cool British conditions.
Plants that don’t do well in a polytunnel
Many plants thrive in polytunnels, particularly annuals and perennial crops. These crops will produce more and grow faster than in their natural surroundings. Some of these crops will even grow larger than they would outside. For example, summer cauliflowers can grow up to five feet tall.
Potatoes are another plant that thrives in polytunnels. They can withstand the cold and protect themselves from pests. Peppers also need protection from the elements, so they can be grown in polytunnels. Likewise, lettuce is often a target for pests, so growing it in a polytunnel will protect it from both the elements and insects.
One drawback of polytunnels is that they are prone to drought. If you are growing plants that need good air flow, you might want to consider a greenhouse instead. Keeping your polytunnel clean can also help increase the longevity of your polytunnel, and increase the amount of sunlight and heat it can hold. Ladybugs and other beneficial insects can help control pests.
If you’re worried about cold, a polytunnel isn’t the best place for lemons or oranges. These fruits are cold-hardy, but they need warm, sunny conditions to fruit. However, if you want to grow citrus plants, you should consider planting them in a polytunnel in a large pot. Then, you can move them to a sunny wall or patio during the summer months.
