Guide for Cultivating a Thriving Greenhouse Garden for Amateur Gardeners

=========================================================================

A greenhouse garden can be a rewarding venture, especially in cold climates. By choosing the right greenhouse and implementing suitable strategies, you can grow a variety of crops, including warmth-loving and tropical plants, throughout harsh winters.

Choosing the Right Greenhouse

The best greenhouses for cold climates offer excellent insulation, temperature control, and protection from frost. Insulated, heated greenhouses or domes with thermal mass systems are ideal choices. These structures often incorporate features like insulated foundations, double glazing, and passive or active heating systems to maintain stable growing environments year-round.

Some specific greenhouse types and features suitable for cold climates include:

1. Insulated Greenhouses with Thermal Mass and Heating: Using materials like insulated concrete forms (ICF) for foundations and incorporating climate battery systems can create an energy-efficient and stable indoor climate, ideal for cold regions.
2. Heated Greenhouses or Controlled Environment Agriculture (CEA) Systems: These greenhouses have integrated heating and ventilation systems to maintain consistent warmth, allowing year-round production of heat-loving crops.
3. Double- or Triple-Glazed Structures: These retain heat better than single-glazed or plastic-covered hoop houses, providing superior insulation to extend the growing season significantly.
4. Additional Internal Layering for Insulation: Adding row covers, cold frames, or thermal blankets inside the greenhouse creates microclimates and additional barriers against cold, effectively extending the growing season and protecting delicate plants during freeze events.
5. Dome or Geodesic Greenhouses: Their shape offers structural strength to withstand snow loads and promotes good air circulation and heat retention, especially when combined with underground thermal systems.

Preparing the Greenhouse

At the end of the growing season, it's essential to wash the greenhouse thoroughly to discourage bugs and prepare for a fresh start in the spring. Chickens can also be allowed to scratch in the greenhouse to remove nesting insects. A shade survey in April is recommended for uncertainty about the sun's angle.

Caring for the Greenhouse Garden

Temperature control and air circulation are critical factors for a successful greenhouse garden. Hoop houses are easier to ventilate than other structures. A shade cloth is a must, especially in spring for young plants. Day-neutral strawberries are a great plant for the greenhouse garden, producing earlier and longer than outdoors. Choose varieties of cool weather crops that grow fast and mature in less than 50 days.

Watering individual plants with a hose from the water tank or a bucket is preferable. Irrigating a warm greenhouse with well or tap water can shock tender plants. The water in a greenhouse should be warm, and freezing temperatures can lead to higher humidity levels, which can harm plants. A water supply is a major factor for a successful greenhouse garden.

Greenhouse Location and Soil

A great location for a greenhouse has a lot of morning sunshine and, depending on location, some shade in the afternoon. The soil in a greenhouse does not recover as quickly as in an outdoor garden. A no-till garden can be practiced in the greenhouse and the entire garden. Soil can be improved or replaced in a greenhouse.

Greenhouse Gardening for Beginners

Beginners should start greenhouse gardening in late spring when the risk of frost is over. A decent-sized greenhouse and thermal mass are important for temperature regulation. Misting systems should not be used in full sun to prevent burning leaves. Cool weather crops are planted in a way that leaves space for the main crop, such as along pathways or in between rows.

For a winter greenhouse garden, a location with excellent natural light all year round is best. Closer to the last frost day, heat-loving plants like tomatoes, peppers, cucumbers, and eggplants are replanted or interplanted. Active or passive heating and/or a frost blanket are necessary for cold and frosty nights.

Growing Tropical Plants in the Greenhouse

The greenhouse allows for the growing of plants that need warmer weather than the local climate can offer. Tropical plants like figs, lemons, and grapes can be grown in the greenhouse, with some requiring indoor movement during cold months. Irrigating a warm greenhouse with well or tap water can shock tender plants, so it's best to use warm water.

Conclusion

Many types of greenhouses are available for different uses. Herbs are a must for the greenhouse garden, including basil, ginger, stevia, and lemongrass. In spring, the soil is soaked well, washed off, and a new layer of compost is added to the soil. Greenhouses without soil can be built using grow bags, wicking beds, raised window protected gardens, or hydroponics. The water in a greenhouse should be warm, and freezing temperatures can lead to higher humidity levels, which can harm plants. A water supply is a major factor for a successful greenhouse garden. Electric heaters can be a temporary solution. Insulation is important to prevent heat loss.

1. A geodome greenhouse, with its structural strength and thermal properties, is an excellent choice for cold climates.
2. After a growing season, consider planting a cover crop in the greenhouse or allowing chickens to scratch the soil for pest control before spring planting.
3. In cold climates, the use of compost and green manure helps enrich the greenhouse soil, improving its fertility.
4. During winter, family members can enjoy harvesting home-grown fruits and vegetables from the greenhouse.
5. In the greenhouse lifestyle, hydroponics allows for growing plants without soil, making them easier to maintain and less susceptible to pests and diseases.
6. Some greenhouse gardening tips for beginners include starting plants in late spring, using a misting system carefully to avoid burning leaves, and planting cool weather crops that mature quickly, such as lettuce and spinach.
7. The lifestyle of a greenhouse gardener often centers around water management, as providing warm water and regulating humidity levels is essential for plant health and growth.
