The Benefits of Backyard Greenhouses

Introduction to Backyard Greenhouses

A backyard greenhouse is a gardener’s dream.

It allows you to cultivate plants, fruits, and vegetables year-round, regardless of the weather conditions outside.

They provide a controlled environment, ensuring your plants are protected from harsh elements while getting the necessary heat, light, and humidity to thrive.

These structures come in various sizes and forms to cater to different needs – from small ‘grow houses’ ideal for balconies or small gardens; through medium size ‘lean-to’ greenhouses attached to your house; up to large standalone structures for those with more space.

By choosing the right type of greenhouse for your garden or backyard, you can extend your growing season, protect delicate plants and even experiment with exotic species that wouldn’t usually survive in local climates.

Key features of backyard greenhouses include:

• Controlled Climate: Greenhouses enable you to effectively manage temperature and humidity levels, which is crucial for plant growth.
• Extended Growing Season: With a greenhouse, you’re not confined by seasonal changes. You can grow all kinds of crops throughout the year.
• Protection from Pests: Backyard greenhouses offer an additional layer of protection against common pests that could damage your plants.
• Increased Plant Production: As a result of these benefits, using a greenhouse often leads to healthier plants and higher yields.

Understanding how best to use a greenhouse can take time, but it offers substantial rewards.

From starting seedlings earlier in the year to late-season harvesting of warm-weather crops such as tomatoes or cucumbers – it’s a garden addition that opens up many exciting opportunities.

1. Temperature Control

Backyard greenhouses require regular upkeep to maintain a temperature suitable for plant growth and healthy crop yield. Overheating a greenhouse increases the risk of pests, mold, and diseases.

One of the best ways to keep your greenhouse cool is by increasing airflow through ventilation systems. These can be installed manually or through automation, such as automatic vent openers.

Roof vents can also help ventilate a greenhouse and should be situated at the top of the structure so hot air is blown out as it rises.

You may even install louvered vents (intake shutters) on either side of your greenhouse to bring in cooler air from outside.

Installing a fan system is one way to enhance airflow in your greenhouse. When combined with louvered vents, fans can double or even quadruple the movement.

You can also add a heating system to your greenhouse to help it warm up. This is an affordable and straightforward solution for achieving proper greenhouse temperature control.

Heating options vary, such as traditional hydronic systems that use a boiler and hot water pipes to heat the greenhouse.

Some of these systems even incorporate a controller with a temperature monitor so you can ensure the greenhouse remains at your desired temperature.

Other heating methods to keep your greenhouse warm include solar and fan power or an electric heater that can be installed inside the structure to help it remain comfortable throughout winter.

Other effective methods for maintaining a stable greenhouse climate include creating thermal mass, placing water jugs in shaded areas, and using a data logger to monitor greenhouse conditions.

Due to the sheer volume of plants in your greenhouse, heat can build up quickly inside. Therefore, they all must get properly watered to help them survive in this heat by giving them essential nutrients for growth.

Additionally, controlling the humidity in your greenhouse is essential as excessive wetness can stress plants and encourage mold or fungi growth – leading to decreased crop quality and lower yields.

2. Pollination

Pollination is an essential process that all fruit-bearing plants require to produce a successful harvest.

Without pollination, the fruit will not form and produce seeds, so you must find ways to ensure your greenhouse plants get the pollen they require for healthy development.

Fortunately, backyard greenhouses can offer several key elements to promote pollination even without natural pollinators. The key is knowing what needs to be pollinated and when.

The University of Kentucky, Cooperative Extension Service, recommends three easy steps to ensure your flowers are pollinated correctly: shaking, tapping, and vibration.

This allows the plant to release pollen from male flower parts into its female structures.

Shaking and taping plants can be done with a soft hand or using vibrating tools like an electric toothbrush. You could also use a feather or brush to collect pollen from male flowers and transfer it to female ones.

Bumble bees are commonly employed in greenhouses, but other bees can also be released to improve plant pollination.

According to a 2001 study, bumble bees proved more successful at fruit production for tomatoes in commercial greenhouses than honey bees.

Some growers are opting to introduce beneficial insects such as ladybugs or green lacewings that can aid pollination. These bugs search the plant surfaces and undersides for food or shelter, depositing pollen along the way.

One option to consider is device pollination, which involves gently rubbing the bottom part of a bloom with pollen grains and moving them onto another flower.

While less damaging than manual pollination, this method can be expensive and time-consuming on a large scale.

In addition to these methods, you can purchase or release several bee hives into your greenhouse to assist with producing fruits and seeds.

While these hives are not cheap, they can be highly efficient and provide numerous advantages.

Backyard greenhouses can be challenging to manage, but they offer the potential to be an invaluable asset in cultivating your crops.

By controlling temperature, water, and fertilization in your greenhouse, you’ll help ensure optimal growth for food crops.

By providing adequate airflow, avoiding water stress, and encouraging pollination, all these elements contribute towards producing healthy, profitable, and healthy vegetables with great flavor.

3. Water Conservation

Water conservation is a top priority for gardeners.

Greenhouses help reduce evaporation and air humidity, leading to healthier plants.

The ideal greenhouses have a minimal environmental impact and often use recycled materials like polycarbonate, wood, and aluminum.

These materials typically have long lifespans and don’t need as much upkeep as masonry or brick structures.

Another advantage of greenhouses is that they enable you to grow flowers, fruits, and vegetables year-round. Plus, these items can easily be transported and stored for future use.

Aside from increasing yields, greenhouses also save water. They are typically equipped with drip irrigation systems that only run water when necessary, dramatically cutting back on the overall usage of freshwater.

Some greenhouses feature automatic vents that shut off automatically when not in use, and they feature heaters to regulate temperature control.

Greenhouses can be tailored to fit your garden space and needs. The size, shape, frame material, and finish all depend on how you plan to utilize your greenhouse.

It’s essential to locate your greenhouse in an area with at least six hours of direct sunlight per day during winter, especially if your area experiences long, cold winters.

Avoid selecting sites near trees or objects that will cast shadows during the summer.

Furthermore, ensure your chosen site has adequate drainage.

It will prevent weeds and muddy floors from growing in the area. Furthermore, regularly cleaning and pruning the greenhouse is essential.

If your area has a high water bill, installing a water-efficient greenhouse could be worth the expense. Not only will it save you money on water expenses, but it will also keep your crops healthy and vibrant.

The greenhouse industry has long been known for its water conservation practices.

To encourage their adoption, educating nursery and greenhouse growers on these new conservation techniques can be an effective means of increasing their awareness.

4. Greenhouse Varieties

Greenhouses offer an ideal environment for growing a wide range of plants year-round while helping you save money by growing your own food.

In addition to vegetables and flowers, greenhouses can also be utilized for cultivating exotic or tropical plants like cacti, orchids, and Venus fly traps.

Backyard greenhouses come in an extensive selection of styles, sizes, and prices. You must select the one best suited to your individual needs and budget.

Your choice of the greenhouse will depend on its intended use, such as propagating seeds or growing crops indoors full-time. Consider your local climate and other buildings on your property when deciding.

Freestanding: A freestanding structure is often preferred for gardeners who want to cultivate crops without other structures nearby. While this option costs less than lean-to or even-span greenhouses, it requires additional work.

Window-Mounted: For those who only want to grow a few plants with minimal heating and cooling costs, window-mounted greenhouses are ideal.

These structures come in various sizes to fit most standard window frames and require minimal installation tools.

Shape: Greenhouses with pitched roofs come in all shapes and sizes, from square to round.

The shape of your greenhouse will determine how much light reaches your plants and what temperature they experience.

Air Flow: Proper airflow is essential to maintain your greenhouse’s temperature and keep pests at bay. This can be achieved with vents in the roof and walls as well as opening the main door occasionally to allow a breeze through.

Watering: If you plan on cultivating a large crop like tomatoes, peppers, or squash in your backyard greenhouse, an automatic watering system may be beneficial.

This saves time and ensures your crops receive adequate water for strong, healthy, fruitful growth.

A greenhouse is an excellent way to provide your plants with a controlled environment, but you must consider what varieties you want to grow before investing.

Hot-season veggies like tomatoes or peppers require additional lighting and/or trellising in a backyard greenhouse. In contrast, cool-season veggies such as broccoli and spinach can thrive without additional lighting requirements.
