Cleaning Your Polytunnel

Updated: Jan 30

Cleaning your polytunnel is important to maintain a healthy environment for your plants, and to prepare it for the next growing season. Here are some steps to follow when cleaning your polytunnel:

Remove all plants and debris:

As we mentioned in the December blog, once the growing season is over you should remove all plants, vegetables, and debris from the polytunnel. This includes roots, leaves, and any remaining fruits. Clear the beds and paths to make sure nothing is left behind.

Dispose of the debris, compost any organic materials, and remove any diseased plants to prevent any potential disease from carrying over to the next growing season.

Clean the polytunnel structure:

Use a mild detergent and water to clean the inside of the polytunnel structure. Pay extra attention to the corners, as these areas can collect dirt and debris leading to disease and disrepair. Scrub any stains or mildew with a soft brush.


Use a mild disinfectant such as 10% bleach solution to clean the inside of the polytunnel, this will help to eliminate any pathogens or pests that may be present. Be sure to rinse the polytunnel thoroughly with water to remove any remaining disinfectant.


Make sure the vents are clean and in working order, Check that the door and window opening mechanism is working properly, this will help to provide proper ventilation and airflow throughout the polytunnel.

Repair any damage:

If necessary, check the polytunnel cover for any rips or holes and repair them to prevent drafts and leaks. Polytunnel tape offers a strong and reliable repair to any tears or holes and is available to order on the Polygrow website.

Check the structure:

Look over the whole structure, and ensure that the frame, gutters, and supports are all in good condition. Check and brush and oil gates and closures. If any repairs are necessary, make sure to address them before starting the next growing season.

Depending on the use of your tunnel, the location and the weather conditions some polytunnels may require cleaning at the end of each season, and some every couple of seasons. Just be sure to address any pests or diseases or tears or disrepair as soon as you notice them. It is better to address issues immediately to prevent them from spreading.
