Did You Know?
1. Greenhouses work in winter by utilizing insulating materials, such as double-glazed windows or inflated plastic curtains, to trap heat and maintain a stable temperature inside.
2. Did you know that some greenhouses use a technique called “thermal mass” to store heat during the day and release it during the colder nights, helping to regulate the temperature even in winter?
3. The concept of greenhouses dates back to ancient Rome, where the Roman emperor Tiberius had special houses built to grow cucumbers all year round, including during winter.
4. In certain regions, greenhouses in winter are equipped with advanced heating systems that can mimic specific climates, allowing farmers to cultivate exotic plants or fruits that would otherwise be impossible to grow during colder months.
5. One of the challenges faced by greenhouses in winter is controlling humidity levels. Excess humidity can lead to the growth of harmful molds and diseases, so greenhouses often incorporate ventilation systems to regulate the moisture content in the air.
Insulating The Greenhouse With Horticultural Bubble Wrap
Insulating a greenhouse is crucial to create a warm and protected environment for tender plants during the winter months. One effective method of insulation is using horticultural bubble wrap. This material not only provides better insulation but also allows more light to penetrate the greenhouse.
By insulating the greenhouse with horticultural bubble wrap, you can minimize heat loss and maintain a more stable temperature inside. The air-filled bubbles act as a barrier, preventing cold air from entering and warm air from escaping. This insulation method is relatively inexpensive and easy to install.
It is essential to cover all the surfaces of the greenhouse with bubble wrap, including the walls, roof, and end panels. By doing so, you create a layer of insulation that prevents cold drafts and keeps the warmth trapped inside. Additionally, the bubble wrap allows sunlight to pass through, providing much-needed light for the plants.

Choosing The Safest Heating Option: Electric Heating
When it comes to heating a greenhouse over winter, safety should be a top priority. Electric heating systems are the safest option as they do not release extra moisture into the air like propane and paraffin systems. Excess moisture can lead to high humidity levels that can favor the growth of mold and fungal diseases.
Electric heaters come in various forms, such as fan heaters, greenhouse heaters, and heated propagators. These devices convert electrical energy into heat, providing a controlled and consistent source of warmth for your plants.
By using electric heating, you can easily regulate the temperature of your greenhouse according to the needs of the plants. This ensures that the environment remains optimal for their growth and development.
Ensuring Even Heat Distribution With Fan Heaters
In order to distribute heat evenly throughout the greenhouse, it is highly recommended to use fan heaters. Fan heaters play a crucial role in circulating warm air and preventing cold spots within the greenhouse. This ensures that all plants receive a consistent level of heat, which in turn promotes healthy and robust growth.
To effectively utilize fan heaters, place them in an open, central spot at one end of the greenhouse. Angling the heaters to direct the airflow above the plants is important to ensure adequate circulation and coverage. Avoid placing the heaters near water sources to prevent any potential hazards.
By employing fan heaters, you can achieve optimal heating conditions and create a more stable environment for your plants during the harsh winter months.

Using A Thermostat For Efficient Heating
Heating a greenhouse efficiently is important for the well-being of the plants as well as for conserving energy and reducing costs. Using a thermostat is a smart way to achieve this goal.
A thermostat allows you to program and regulate the temperature inside the greenhouse. By setting the desired temperature range, the thermostat will automatically turn the heating system on and off as needed. This avoids excessive heating and ensures that energy is only consumed when necessary.
Investing in a high-quality thermostat can save you money on energy bills and create a more efficient heating system for your greenhouse. It provides a precise means of maintaining a consistent temperature, reducing the risk of overheating or freezing.
Maintaining The Right Temperature For Different Plants
Different plants have varying temperature preferences, and it is essential to meet their specific needs to ensure their survival during winter. Maintaining the right temperature is crucial for protecting tender plants and encouraging their growth.
For most tender plants, a minimum temperature of 3°C (37°F) is necessary to keep the greenhouse frost-free. However, some plants, such as pelargoniums, half-hardy fuchsias, and citrus trees, prefer a minimum temperature of 7°C (45°F) and thrive best at around 10°C (50°F).
Delicate plants that cannot tolerate temperatures below 13°C (55°F) should be overwintered in a conservatory rather than a greenhouse. It is important to research the specific temperature requirements of the plants you are growing and adjust the heating accordingly.
Understanding the temperature preferences of your plants allows you to provide them with the ideal conditions for growth. By doing so, you can ensure that they survive the winter season and continue to flourish in your greenhouse.

Frequently Asked Questions
Are greenhouses useful in winter?
Greenhouses are incredibly useful in winter for a variety of reasons. Not only do they provide protection to delicate plants, preventing them from succumbing to frost, but they also enable the growth of robust crops, such as salads and herbs, even in the colder months. With an unheated greenhouse, overnight temperatures can be up to 5°C warmer than outside, effectively safeguarding plants from frost except in extreme winter conditions. Whether you wish to preserve your tender plants or continue cultivating resilient crops, greenhouses prove indispensable during the winter season.
Are greenhouses safe in the winter?
Greenhouses can be safe in the winter as long as the temperature is properly regulated. It is crucial to choose the right temperature for the plants being cultivated. Maintaining a minimum temperature of 3C (37F) can prevent frost, but certain tender plants thrive better at higher temperatures. Keeping the greenhouse at a minimum of 7C (45F) is recommended for plants like pelargoniums, half hardy fuchsias, and citrus trees, while a safer temperature of 10C (50F) ensures their optimal growth and well-being. By carefully monitoring and adjusting the temperature, greenhouses can provide a suitable environment for plants to thrive during the winter months.
Does a greenhouse work for all seasons?
Yes, a greenhouse can be designed to work in all seasons. By insulating the structure, a greenhouse can retain heat and prevent drastic temperature changes, creating a more stable environment for plant growth. Furthermore, greenhouses utilize the sun’s energy for both plant growth and heating, making them capable of sustaining a suitable temperature throughout the year. Whether it is winter or summer, a well-insulated greenhouse can provide a favorable climate for plants to thrive in all seasons.
What happens if greenhouse gets too cold?
When a greenhouse becomes too cold, the risk of freezing or chilling injury to the plants significantly increases. In freezing conditions, the damage occurs as ice crystals form within the plant cells, leading to ruptured cell walls and ultimately causing cell death. This can result in wilting, discoloration, and even death of the plants. Additionally, for cold-sensitive plants accustomed to tropical climates, the cold temperatures can disrupt their physiological processes, affecting growth and development. Therefore, it is crucial to maintain a suitable temperature in the greenhouse to prevent freezing injury and ensure the health and survival of the plant species being cultivated.
