Winterize a Greenhouse

Winterizing a greenhouse is an incredibly important thing that needs to be held annually. How you work on the greenhouse in the fall would determine the safety of its structure in the winter, as well as the harvest of the next season. How to prepare the greenhouse for winter? Let’s figure it out.

Why Do You Need to Prepare a Greenhouse for Winter?

Plants need greenhouse conditions to protect themselves from their main enemy – the winter cold. Inside the greenhouse, thanks to the ingenious design and the materials from which it is made, a constant temperature is maintained and the humidity necessary for plants to develop successfully is maintained. But precisely because of this ability of the greenhouse to create favorable conditions for plants, there is a danger that weeds and pathogens may also feel great in a warm and humid environment. The bacteria preserved in the greenhouse after harvesting can safely survive the winter, and in the spring they can attack the young seedlings. And then there can be no healthy harvest.

Start with Cleaning

First, remove the old plants. Tops of tomato, cucumbers, peppers; as well as the remaining bushes of greenery, weeds must be dug out of the ground, raked into a separate heap, and burned. Also, plant residues (except weeds) can be used as raw materials for compost. If you do not get rid of dried stems in time, they can become a habitat for many pests. Therefore, the preparation of the greenhouse in the fall must necessarily include the cleaning of dead plants. After harvesting, take away inventory from there, remove all garters for plants. Do not reuse them – pathogens can overwinter on them.

Thoroughly wash the greenhouse walls with a cleaner and disinfectant to remove adhering leaves and pathogens. You can also use a dishwashing detergent to do this. Separate hard-to-reach areas are additionally treated with brushes. Particular attention is paid to the corners: cobwebs accumulate there, there may be insect nests. If your greenhouse is made of polycarbonate, use a non-scratching sponge or rag. If you need to clean wood, you can use diluted wood oil soap. Glass greenhouses can be washed well with ordinary soapy water. You can also use a special glass cleaner. The surfaces of such a greenhouse should be washed both inside and outside.

Disinfect the Soil in the Greenhouse

There are several ways to do this:

  • Digging. To get rid of pests and pathogens in the soil, you need to thoroughly dig up the soil without breaking lumps. Such land frees better in winter, and all unwanted inhabitants of greenhouse beds die from frost.
  • Use boiling water. Unlike the first, this method works oppositely. Its essence lies in the fact that the soil is watered with boiling water and covered with a film. So the soil warms up to a high temperature and all living organisms in the substrate also die.
  • Fumigation. One of the best methods of disinfecting a greenhouse is considered to be fumigation. It allows you to get rid of ticks, fungi, and mold, as well as bacterial infections that live not only in the soil but also in the details of the greenhouse.

Provide Airflow in the Greenhouse

Unfortunately, heat alone is not enough for your plants to survive the winter with dignity. As with any time of the year, plants need fresh air to stay healthy and grow well. But how to ensure good circulation if it’s too cold outside? This is where ventilation systems or internal greenhouse fans come to your rescue, which can help keep the indoor air flowing warm and provide air circulation. By setting the fans or ventilation system to a low setting directed towards your plants, you can provide them with a constant fresh airflow that would keep the plants breathing intensively during cold weather. Moreover, it can help prevent harmful moisture build-up on the leaves.

Make Sure There Are No Holes

Even the smallest gap can allow the cold winter air to pass through. Autumn is a great time to do a little renovation in the greenhouse. Be sure to check your greenhouse for cracks, gaps, and holes. Close the holes and keep the greenhouse warm from bad weather. If the damage is serious, then you should consider replacing parts. It is much more economical to do now than to completely repair the greenhouse after the winter.

Make sure all moving parts of the greenhouse (such as door handles, hinges, and vents) are lubricated with grease or silicone-based product to ensure reliable operation when the temperature drops. Be sure to close all windows and doors are securely, otherwise, winter winds can cause serious damage.

Of course, patching up all the holes is just the first step to protecting the greenhouse plants from the cold winter weather. The greenhouse must be insulated.

When a cold breeze blows outside, gardeners need to make sure their plants are warm enough to grow all winter. How to winterize a greenhouse? An integrated heating system or even a conventional heater can help you with this. If you do decide to use a heater, be prepared to service it regularly. Autumn is a great time to get ready and check the device, and if necessary, fix it. Gardeners need to make sure that the heating block provides enough power for the size of the greenhouse, otherwise, your plants may freeze. We strongly recommend that you purchase a spare heater in case the main one fails.

It’s also a good idea to get a backup heater that may help you in the event of a power outage. Gas or battery-powered heaters are an excellent option.

Another way you can insulate a greenhouse is to veneer the greenhouse with inner plastic, thereby creating double glazing. Regular bubble wrap can be an inexpensive option. Prefer larger bubble films, as they provide better insulation and allow more light to pass through. Simply glue this clear bubble wrap to the interior walls, ceiling, and windows of your greenhouse and your plants would thank you.

If you are willing to spend some money, then get a special garden bubble wrap to winterize the greenhouse. This film is renowned for its good UV resistance and would last you much longer than the ordinary film from under the packaging of your online purchase.

Plant Winter Greens

After all the procedures, you can safely plant whatever you want, or rather everything that can grow in your climate in winter. Many vegetables are well suited to survive the winter in a greenhouse. By late fall, you can start planting carrots, leeks, or winter greens such as spinach. But this must be done strictly before the frosts begin, as digging the frozen soil is not an easy task.

Preparing a greenhouse for winter is not a very difficult task, but it takes some time. Take care of the greenhouse in advance, and later you would not have to worry about a damaged frame or diseased plants. Correctly carried out the preparation of the greenhouse for winter would allow it to be operated for many years to come.
