Use a Polytunnel (Tunnel Greenhouse) to Protect Your Plants From Frost

Posted on 27th Dec 2010 @ 2:44 PM

A polytunnel is a fantastic alternative to a greenhouse or coldframe for keeping your plants protected during the cold winter months. A polytunnel cloche is far cheaper than other methods of plant protection and can be placed directly over a plant in your garden meaning that your plant does not need to be uprooted and moved.

A poly tunnel can protect against frosts and increase the longevity of your plants. Most people will recognise the semi-circular shape of a poly tunnel without knowing the correct name for this garden product.

Frosts and cold weather cause the water in plant cells to freeze which damages the cell wall. It is easy to spot frost damage on a plant; their growth will become limp, blackened and distorted. A poly tunnel can prevent frost damage and are extremely affordable.

What is a polytunnel?
A Poly tunnel is essentially a polythene sheet supported by a row of metal hoops that you can place over your plants. The tough UV stabilised polyethylene forms a complete barrier against the cold, it retains humidity and warmth and fully protects your plants from harsh weather and frosts. A poly tunnel normally has a door at each end to allow easy access to your plants. The door also provides good ventilation that can be adjusted depending on the temperature.

Polytunnels are far cheaper than greenhouses and coldframes. Made from polyethylene they are extremely durable and unlike the glass panes on a greenhouse will not shatter or become hazardous to children.

As well as protecting your plants in the colder months using a polytunnel will extend the growing and crop producing period of your plants. A poly tunnel will help to prolong crops during the autumn and can also be used to warm the soil for early planting in the spring.
