Introduction To Year Round Growing in GreenHouse

Greenhouses are a fantastic way to extend the growing season and cultivate plants yearly. With the right techniques and strategies, you can create a controlled environment that provides optimal conditions for plant growth.

Growing plants in a greenhouse not only protects them from harsh weather conditions but can also yield better crops than growing them outdoors.

There are some specific challenges to planning and caring for your year-round greenhouse to grow the best produce. A greenhouse requires diligent management of all aspects, from heating to irrigation.

Here’s everything you need to know about growing year-round in a greenhouse.

Benefits Of Greenhouse:

A greenhouse has several benefits that make it a valuable tool for agriculture and plant cultivation. It’s a great way to enjoy local produce year-round, whether you’re selling it or enjoying it at home. Some of the key advantages are as follows:

Extended Growing Season: 

In greenhouses, plants can flourish outside their natural growing season because of the controlled environment created by the greenhouse. As a result, farmers will be able to grow crops for a longer period, providing them with more flexibility and opportunities for continuous production.

Temperature Control:

Control of temperature is precisely controlled in greenhouses, protecting plants from extreme weather conditions. Temperature can be precisely controlled in greenhouses, protecting plants from extreme weather conditions. Temperatures around 70 degrees F (21°C) are ideal for cool-season crops, while temperatures around 90 degrees F (32°C) are ideal for warm-season crops.

Pest and disease control:

A greenhouse’s enclosed environment protects plants from pests, insects, and diseases. It promotes healthier and more sustainable agricultural practices by reducing the use of chemical pesticides.

Water usage optimization:

Water can be efficiently managed in greenhouses through irrigation systems. Water loss through evaporation is minimized due to the enclosed structure, and precise control over watering can be maintained for specific crops.

Enhanced crop quality:

Greenhouses provide optimal conditions for plant growth, resulting in higher-quality crops. In horticulture and specialty crops, appearance, flavor, and size are particularly important.

A Year-Round Production System:

The ability to control light and temperature makes greenhouses are ideal for cultivation throughout the year. For regions with long winters or limited sunlight, as well as crops that require specific day lengths for flowering and fruiting, this is essential.

Increased Crop Yield:

By providing an ideal environment for plants to thrive, greenhouses help increase crop yields. Farmers can benefit from this increased productivity in terms of food security and economic sustainability.

Utilization of resources:

A greenhouse can be designed to be resource-efficient by incorporating technologies such as drip irrigation, rainwater harvesting, and energy-efficient heating and cooling systems. In this way, sustainable farming practices can be promoted and agriculture’s environmental impact can be reduced.

VENTILATION IN WINTER GREENHOUSES

Insulation is important, but ventilation is equally important – and you must strike a good balance between the two. In addition to heat, your plants require adequate carbon dioxide and oxygen levels for nighttime transpiration. The presence of moisture is also detrimental to plant growth, which is why good winter greenhouse ventilation is essential to preventing the growth of disease or mildew.  

Open your greenhouse doors early in the morning and close them before the sun sets.

There are many things you can grow in a greenhouse in winter! The best thing to do is just try it; experiment with different plants in different containers and enjoy the results! 

Food that Can Be Grown In a Greenhouse 

During the spring growing season

Plant some hardy vegetables to kick off the planting season:

• Lettuce
• Peas
• Leek
• Onion
• Shallot slices

The mid-spring planting season

As the weather begins to warm, tender plants are perfect for growing in greenhouses. Among the best plants to plant in mid-spring are:

• Cucumbers
• Squash
• Pepper
• Tomatoes
• Basilisks

Note: It is easy to grow houseplants in a greenhouse with less care, whether they contain fruit or not.  Greenhouse-grown plants also require more frequent watering and fertilization. Greenhouse-grown vegetables can be harvested earlier than outdoor-grown vegetables.

Growing season in the summer

As summer approaches, move some of your spring plants outside to make room for other crops. For your plants to grow all summer long, you will need to protect them from the heat through strategic ventilation and vigilant watering.

During the summer growing season, heat-loving plants include:

• Beans
• Squash
• Tomatoes
• Pepper
• Carrots
• Potatoes

The winter growing season

For greenhouse growers living in colder climates, the winter season presents plenty of challenges. While winter greenhouse growing may present some challenges, it can also be a time to clean, repair, and reset for the year ahead. During this time, you can evaluate your greenhouse layout and make any necessary changes.

It is ideal to grow hardy, frost-tolerant plants in greenhouses during the winter season. Root vegetables and herbs can thrive in the winter months if they are properly cared for and can provide fresh, healthy produce when outdoor growing is not possible.

With a fully controlled growing environment, you don’t have to change your greenhouse growing strategy. Using automated lighting and heating systems, you can grow bountiful crops throughout the year.

Winter Vegetables To Grow In A Greenhouse

Growing root vegetables and leafy greens in greenhouses during the winter is a good option in the Northern Hemisphere. A heated greenhouse with climate control can accommodate virtually any crop at almost any time of year, but an unheated greenhouse requires extra consideration, and not every crop can be grown there.

For winter crops, an unheated greenhouse isn’t necessarily a deal breaker. Unheated greenhouses can be beneficial for certain plants when they are exposed to colder temperatures during the winter. In your greenhouse, you can grow the following winter vegetables:

• Endive
• Kale plant
• Swiss Chard
• Parsnips
• Potatoes
• Beets
• Carrots
• Brussels sprouts

Herbs in Winter Greenhouse:

In a winter greenhouse, many herbs can be grown successfully. The following are some examples. The plants require minimal space and can be harvested repeatedly.

•  Parsley
•  Cilantro
•  Chives
•  Thyme 

During any growing season, make sure your winter crops have enough room to grow and establish their roots. Plants can be separated into groups using containers to optimize space. To grow the highest-yielding crops, it’s a good idea to separate growing containers so that leaves don’t touch and remove weaker plants to allow the stronger ones to grow.

Despite the cold, indoor temperatures can become quite hot during sunny winter days, requiring proper airflow and ventilation to regulate temperatures and prevent stress on plants.

Conclusion

Growing plants year-round in a greenhouse requires careful attention to temperature control, light management, watering, soil quality, and pest control. By implementing these strategies, you can create an ideal environment for your plants to thrive regardless of the season. With dedication and proper care, you can enjoy a bountiful harvest all year long.
