How greenhouses extend the growing season

Are you tired of only being able to grow vegetables for a few months out of the year? Using a greenhouse, you can extend your growing season by up to 60%! You can enjoy fresh produce well into the fall or all year by using row covers, cold frames, or even an unheated or heated greenhouse. Let's explore some techniques to extend your growing season and get the most out of your garden.


Importance of extending the growing season

Extending the growing season is essential for any avid gardener or farmer looking to reap the benefits of their hard work for as long as possible. Greenhouses can lengthen the growing season by up to eight weeks in some areas, providing ample time for crops to flourish. Not only does this mean more fresh produce to enjoy, but it also opens the door to larger harvests and increases productivity during the summer months. However, choosing the right covering option for your greenhouse is essential. Glass, polycarbonate, and plastic films have pros and cons, so proper research and planning are necessary to ensure successful growth. Additionally, the size and orientation of the greenhouse are crucial factors to consider. All in all, extending the growing season through greenhouses produces numerous benefits for both the gardener and their crops. [1]


I. Benefits of greenhouse growing

Early start for spring planting

One of the main benefits of using a greenhouse to extend your growing season is the ability to start planting earlier in the spring. With a greenhouse, you can control the temperature and protect your plants from frost or sudden temperature drops. This means you can start planting your spring crops, like lettuce, spinach, and peas, several weeks before the last frost date in your area. When the weather outside is warm enough to plant, your seedlings will be mature enough to be transplanted outside, giving you a head start and potentially increasing your harvest. Additionally, starting your plants indoors in a controlled environment can lead to more robust and healthier plants, making them more resistant to pests and diseases. So if you want to make the most of your growing season, consider investing in a greenhouse for early-start spring planting. 


Extended fall season

One significant advantage of using greenhouses to extend your growing season is the ability to continue growing even during the cooler fall months. Using a greenhouse, you can create a microclimate that protects your crops from colder temperatures and harsh winds. Additionally, the humidity inside the greenhouse can help prevent plant water loss during dry fall weather. With careful planning and monitoring, you can potentially continue harvesting crops well into the winter months. Some cold-hardy vegetables like lettuce, carrots, and kale can thrive in a greenhouse even as outside temperatures drop. Investing in a greenhouse can significantly extend your growing season, allowing you to enjoy fresh produce for a more significant portion of the year. 


Productivity gains in the summer

One benefit of using a greenhouse to extend the growing season is the potential for productivity gains during summer. The controlled environment of a greenhouse can help plants grow more vigorously and increase their yield. For example, plants like tomatoes and cucumbers can start producing fruit in a greenhouse much sooner than in an outdoor garden. The extra heat and humidity inside the greenhouse can make plants grow bigger and lusher, resulting in a larger harvest. However, it's important to note that not all crops may thrive in a greenhouse environment, and some may fare better outside. It's essential to properly research and plan which crops to grow in the greenhouse during the summer months to maximize productivity gains. [2]


The potential for larger harvests

One of the significant benefits of extending the growing season with greenhouses is the potential for larger harvests. Giving plants a longer growing period gives them more time to mature and produce food. This means you can have multiple harvests from the same plants throughout the year. Furthermore, with the controlled environment of a greenhouse, you can create the ideal growing conditions for your plants, such as optimal temperature, light, and humidity levels. This can significantly increase their productivity and yield. Imagine having ripe tomatoes in December or fresh lettuce in January. With the help of a greenhouse, you can achieve this and more. By extending the growing season, you can enjoy a variety of fresh produce all year round, increase the amount of food you harvest, and reduce your grocery bill. 


Advice on how to extend your growing season using greenhouses.

Greenhouses are one of the best ways to extend your growing season. Greenhouses can protect your plants from harsh weather, allow you to start your seeds earlier, and provide you with a longer growing season. Choose the right location to make the most of your greenhouse, as it should get plenty of sunlight and be free from obstructions. Pick the right size according to the amount and type of plants you plan to grow. Control the temperature, ventilation, and humidity inside the greenhouse with an automatic system, or monitor it yourself. Finally, as with any gardening method, choose the right plants for the greenhouse based on your climate, soil, and gardening goals. With these tips, you can enjoy fresh and healthy produce all year round and optimize your gardening efforts.
