How To Keep The Pests and Bugs out of your Polytunnel Naturally

Can I keep the bugs and pests out of my polytunnel installation naturally? You most certainly can. However, it is important that you plan ahead. The job starts before the company arrives to start on your polytunnel construction.

 


Talking through your concerns and approach to polytunnel gardening with the installation company is the best idea. For instance, they may be able to add extra ventilation. Better airflow will help to control the humidity level in your polytunnel. High humidity contributes significantly to the growth of fungus and mould in any polytunnel installation.

 

Creating a Micro Climate

 

When you are really keen to go down the “natural route”, the job starts long before your polytunnel construction.

 

Many experienced polytunnel gardeners know that what they grow in their polytunnel installation has a huge effect on the environment. In many ways, a polytunnel construction creates a micro-climate in which your plants and crops can thrive.


When you want to make sure that you experience as few problems as possible, the smart thing to do is to do some research. What plants can help to turn your polytunnel installation into a natural micro-climate?

 

Plants To Grow In Your Polytunnel To Keep The Bugs Out

 

In permaculture, plants that keep the bugs and pests under control are often called defence plants. That sounds fancy but is, in fact, not very complicated at all. Most of the plants are easy to grow yourself. You can probably pick them up at your local garden centre.

 

Sage (Salvia officinalis) is a good example of a herb that you can add to your cooking. At the same time, it will help contribute towards pest control in your polytunnel installation. Do make sure that it is the green sage. Purple sage (Salvia splendens) is a favourite snack of slugs and will not help to protect the plants in your polytunnel.

 

Another herb, Hyssop (Hyssopus officinalis) is another good line of defence against pests.

 

If you have a particular problem with slugs in your polytunnel, you should place containers of beer where they enter your polytunnel installation. Slugs love beer and will happily drown themselves in the precious liquid.

 

Growing a variety of onions is another way to support a natural micro-climate in a polytunnel. Believe it or not, onions can help to keep mildew at bay.

 

Improving the Soil

 

Improving the soil is a great way to reduce the chance of pests found in your soil or compost. One plant that does so very efficiently, is Valerian (Valeria Officinalis). As the plant has a range of health benefits for you as well as your polytunnel installation, there is no reason why you should not grow it.

 

Most polytunnel construction service companies have vast experience and knowledge of how you can set up a natural poly tunnel installation. Speak to them at the start of the project and you will find that they would be only too happy to give advice.
