Winter Protection For Your Polytunnel

Polytunnel Winter Protection

If you are interested in establishing a vegetable garden, then polytunnels can provide a great solution. In addition to providing a warm place for growing your own food, these structures are also inexpensive. You can easily find them at a local garden store. Depending on the size of your space, you can grow a range of different crops in them.

Plants that grow well in a polytunnel

Polytunnels can be frosty during mid-winter, and the presence of snow in them can affect the quality of the crops growing in them. However, certain crops are more resistant to winter and can be planted in polytunnels to extend the growing season. These include cabbages, Brussels sprouts, Asian greens, and hardy winter lettuces.

If you have a polytunnel, you can plant the following vegetables into it. Some of these are suited to early autumn sowing. Others can be planted as late as mid-September. Turnips are an excellent late-season crop and can be planted directly into the ground inside the polytunnel. You should plant them at least 10cm apart and keep them moist during the winter.


It is important to ensure that your polytunnel is protected from the winter months. If the conditions are not right, it can lead to damage to the polytunnel. Luckily, there are several options to help you with winter protection. First of all, you can find free stones on classified websites. The stones work by absorbing heat from the sun, and then slowly releasing it during the night. Alternatively, you can purchase a polytunnel with double glazing.

Secondly, you can install a gutter system to collect rainwater from the polytunnel. The gutters can be installed on the sides of the polytunnel, and lead directly into a water tank. These gutter systems can provide water for irrigation purposes. Thirdly, you can buy a different polythene material to help with the cooling process.


It is important to consider winter protection when planning the construction of polytunnels. In mid-winter, frost and snow can affect the plants that grow inside. However, it is possible to protect crops from these elements. There are several simple ways to do this. You can cover plants with row covers, bubble wrap, or horticultural fleece. You can also cover individual plants with plastic cloches.

Snow on polytunnels is not a problem for some structures, but it can cause damage to others. Winter is fast approaching and it is essential to prepare your polytunnels to withstand the harsh weather conditions. In addition, you should monitor them closely during the winter months to prevent any damage from the elements.

Net cloches

Cloches are an excellent way to protect your crops from the cold weather. In addition, they provide additional protection against pests such as rabbits and birds. The netting is usually made of black or opaque plastic, which prevents animals from swooping in and eating your crops. Clear plastic is also a good choice because it traps more heat and is less likely to trap birds. The nets can also help to keep the temperature moderate and prevent fungal diseases.

Cloches are generally low, portable structures that protect plants from weather extremes. They are made of clear plastic or glass. You can connect several cloches together to cover a large area. They provide the same protection as a polytunnel or greenhouse.


Winter protection is a key factor for polytunnels, as these structures are exposed to adverse weather conditions. In particular, frost can damage the crops you are growing inside. Some of these crops include cabbages, kale, Brussels sprouts, Asian greens and hardy winter lettuces.

Fortunately, there are many ways to increase your polytunnel’s winter protection. First, consider the material used for the frame. A steel frame provides a sturdy base that won’t rot or degrade. Polythene coverings are available in different qualities and can last for several years. However, cheaper plastic frames can break or crack easily. If you’re concerned about damage during winter, you might want to consider covering your tunnel with a green polythene covering. This will prevent heat loss and preserve light levels. It also provides a natural barrier for the soil and prevents heavy rain from compacting the soil.


Ventilation in polytunneling is an important part of winter protection for your polytunnel. It helps to prevent moisture and other contaminants from building up inside the tunnel. There are a number of ways you can improve ventilation. Firstly, you can use bubble wrap, fastened with string or cable ties. For best results, opt for UV stabilized bubble wrap.

A good ventilation system will help your polytunnel remain at a constant temperature. Ideally, the temperature inside a polytunnel should be between 25 and 27 degrees Celsius, or 77-81 degrees Fahrenheit. There are several ways to regulate temperature within your polytunnel, including increasing airflow through the structure and lowering the humidity levels. You can also make use of a recording thermometer to see what temperature your polytunnel is at.
