Is A Polytunnel Frost Free?

Is A Polytunnel Frost Free

A polytunnel is an enclosed greenhouse that allows you to control the environment in which your plants grow. You can maintain the temperature of the growing space and control moisture using a variety of tools. Additionally, polytunnels can help keep beneficial insects in, such as ladybugs, aphid midges, and honeybees. Other beneficial insects that may be found in a polytunnel include braconid wasps, ground beetles, damsel bugs, and tachinid flies.

Plants thrive in a polytunnel

The polytunnel is an excellent tool for growing a range of plants. Many perennial crops will thrive in this growing space. In addition, some annuals will also flourish. For example, tomatoes and globe artichokes will grow well. Polytunnels also provide excellent protection for plants during frosty weather. This will help them grow faster and healthier.

Polytunnels are also a great way to extend the growing season for vegetables. They can protect plants from cold, frost, and wind. This means that you can grow a wide range of vegetables throughout the winter. In addition, polytunnels are an excellent place to start seeds and seedlings.

It allows you to extend your growing season

Investing in a polytunnel is a great way to extend the growing season by a couple of months. It allows you to start your seedlings earlier and can grow larger crops than in the open garden. It also offers protection against the heat and pests. Plants will also grow faster and healthier in a polytunnel than in the open.

A polytunnel will also allow you to grow crops in colder climates. You can set it up in any season, although early spring is the best time for germination. The tunnel can be insulated and stay warm in the summer and cool in the winter. You can even set up an artificial Mediterranean climate inside it for a few months to increase the variety of crops you can grow.

It keeps out pests

Pests are the biggest problem that growers face in their polytunnels, but there are some things that you can do to protect your crops. By following a few simple steps, you can keep pests at bay. First of all, you must keep your plants healthy. This will reduce the chances of pest infestations and diseases. You should also try to keep the environment in your polytunnel as clean as possible. This will prevent damp conditions that encourage pests.

Secondly, you should consider using insect sticky pads. These pads are a great way to control pests in your polytunnel. They can be purchased at DIY stores and garden centres and can be used to control harmful insects in your growing area. They can also limit the need for chemical treatments and are particularly effective against aphids and whiteflies. You should replace sticky pads every three or four months or when they begin to fill with insects.

It prevents damp

One of the most important aspects of maintaining your polytunnel is the ventilation system. A well-ventilated polytunnel will run more smoothly and efficiently than one that has poor ventilation. The best ventilation system is one that is designed to allow a through breeze through the polytunnel.

Having a well-ventilated polytunnel is essential to the health of your plants. During the summer months, you should keep the doors open as much as possible. This helps prevent damp and prevents the onset of disease. If you plan to plant crops in the polytunnel during the winter, it is advisable to cover the polytunnel with a fleece.

The temperature inside a polytunnel should be around 25 degrees Celsius or 77 degrees Fahrenheit. Proper ventilation can help control the temperature inside the polytunnel and prevent mould growth. You can also install a dehumidifier to regulate the humidity level. However, humidity levels should not exceed 85% as this is conducive to mould growth.

It prevents fungal problems

If you’re growing vegetables in a polytunnel, you need to be vigilant about preventing fungal problems. These fungi can live in the soil and plant debris. To prevent problems, it’s important to rotate crops, keep the greenhouse clean and disinfected every year.

Growing early potatoes can reduce the risk of blight, which usually appears later in the season. Ideally, you should harvest the first earlies by early July. This won’t prevent blight from forming in maincrop potatoes, but it will help prevent it from taking hold. You can also protect your tubers by earthing them up and mulching them with organic matter.

The use of a polytunnel will also help you to extend your growing season. Your plants will grow faster and mature more quickly. You can also grow vegetables such as asparagus and globe artichokes, which don’t grow well in other climates. In addition, plants will be more productive in a polytunnel than they would in their natural environment.
