Which Flowers Thrive In Greenhouses?

Growing vegetables in a greenhouse can be rewarding for home gardeners, as it allows them to propagate new plants from their existing landscape favorites and get a jump start on their vegetable crops. A list of the best plants that can be successfully grown in a greenhouse, regardless of where you live, includes geraniums, impatiens, chrysanthemums, poinsettias, bouganvilleas, and camellias.

Greenhouses make the most out of the sunlight received no matter your region, allowing you to enjoy a bountiful harvest any time of the year. Some profitable flowers that can be grown in a greenhouse include scabiosa, sunflower, marigold, heritage roses, celosia, and geraniums.

Tropical plants like mandevilla, hibiscus, and orchids will also flourish in a greenhouse. To ensure optimal growth, monitor soil moisture and choose plants that require specific and consistent temperature and humidity.

Succulents are popular and easy to care for in a greenhouse, as houseplants or outside. Popular choices include tulips, daffodils, hyacinths, crocuses, and grape hyacinths. Starting seedlings in late August or early September is recommended.

Selecting the right flowers for greenhouse farming includes roses (60-75°C year-round), orchids (65-80°C year-round), and geraniums (65-75°C spring-fall). African violets, streptocarpus, begonias, and kalanchoe are all flowering greenhouse plants that don’t take up much space.

Finally, pansies are a great option for growing pansies in a garden or in a greenhouse.

What plants are good for greenhouse in summer?

Greenhouses are ideal for summer gardening, especially for hot weather vegetables like tomatoes, cucumbers, peppers, and basil. To control greenhouse temperatures, use shade cloth and heat-storage systems like the Ground to Air Heat Transfer (GAHT®) system. However, the greenhouse may occupy the sunniest spot in your yard, so it’s important to shift what you grow there to plants that like heat and full-sun.

Some gardeners take their garden almost entirely outdoors in the summer, opening up the greenhouse as a sitting area or extra living space. This allows them to create a large outdoor garden, leaving ample space for morning coffee and meetings. For greenhouses with more intense sunshine, add shade cloth to keep the greenhouse at a comfortable temperature for people.

Year-round greenhouse growing involves growing a wide array of crops, both hot and cool, in the greenhouse. To achieve this, add shade cloth and control heat gain, such as using a GAHT® system to store extra heat in the soil for night heating.

What flowers grow well in greenhouses?

Ornamental plants, such as orchids, roses, and African violets, require specific temperature and humidity in traditional greenhouses. For lower maintenance options, consider geraniums, impatiens, chrysanthemums, poinsettias, bouganvilleas, and camellias. Leafy plants like caladiums, maidenhair ferns, air plants, staghorn ferns, and begonias can be added to a greenhouse. Ferns, such as delicate maidenhair ferns and robust tree ferns, can add a tropical touch. Air plants and staghorn ferns grow well in hanging planters for lush vistas.

Not all plants will enjoy extra heat and humidity. The ficus and its varieties prefer a more tempered indoor environment, while fiddle-leaf figs will enjoy humidity but only if it comes with full sun. While some standard houseplants can be placed in a greenhouse, not all plants will thrive in such conditions.

What grows best in a greenhouse in summer?

Salad vegetables like tomatoes, peppers, cucumbers, zucchini, and lettuce are easy to grow and have high yields. They thrive in greenhouses and can be grown up a trellis or wall to save space. Other staples like pole beans and snap peas can also be grown in this configuration. Greens, such as cut and come-again lettuces and microgreens, are essential for a salad and require shallow containers. Onions, carrots, kale, cabbage, and broccoli are also suitable for greenhouses. Cold-hardy plants like leafy and bitter greens and root vegetables can keep you eating fresh all year. Remember to leave space for harvesting these vegetables.

What not to grow in a greenhouse?

Greenhouses are ideal for gardeners as they provide controlled environments that extend growing seasons and protect plants from harsh weather. However, not all plants thrive in enclosed spaces. Some common mistakes to avoid include large trees and shrubs, which can outgrow containers and damage structures. Invasive plants, such as mint or certain ivy species, can quickly overtake other plants and become difficult to eradicate once established in a greenhouse.

To avoid these issues, it is recommended to reserve your greenhouse for compact or easily pruned plants. Additionally, plants with high temperature requirements, such as long-lived perennials, should be kept outside for easier control. By avoiding these common mistakes, you can save time, effort, and disappointment in your greenhouse gardening endeavors.

Are indoor greenhouses worth it?

Indoor greenhouses are compact and portable, allowing for the growth of a wide variety of potted plants, including herbs used in everyday cooking and baking. They also improve air quality by generating oxygen and having air purifying properties. Indoor greenhouses are ideal for people living in condos or apartment buildings without access to a backyard, as they allow them to grow herbs, flowers, or vegetables without worrying about space limitations. They also provide a calming and pleasing aesthetic, making them an ideal solution for those who may not have access to a backyard.

What is the easiest thing to grow in a greenhouse?

Starting a greenhouse gardener can start with high-yield vegetable plants like tomatoes, cucumbers, squash, and peppers. These plants thrive in warm environments and require spring planting and summer nurturing. Fruit trees, which can be grown in a greenhouse, offer temperature control and protection from rain, wind, and frost. These plants can produce a fruitful harvest in the fall. Both vegetables and fruit trees can be beneficial for greenhouse gardening.

What plants grow best in indoor greenhouse?

Indoor greenhouses provide high humidity, which is ideal for tropical houseplants like aroids, ferns, and orchids. Leslie F. Halleck, a certified professional horticulturist, suggests that these conditions can be useful for those struggling to grow these plants indoors. Glass cabinets or cold frame indoor greenhouses can be used to grow various plants, depending on the desired environmental conditions. Warm-loving tropical species with low requirements for ventilation, light, and winter rest are the easiest to grow in glass containers.

Edible plants like herbs and leafy vegetables also thrive in indoor greenhouses, but harvests may be low unless grow lights are set to maximum levels. Halleck recommends focusing on “dwarf” or “miniature” edible herbs and vegetables like Micro Tom tomato or Boxwood basil, as they are easier to grow indoors and don’t require as much intense light.

What are the 5 disadvantages of a greenhouse?

Greenhouse farming presents a number of challenges, including the necessity for expertise, high initial costs, the requirement for extensive knowledge to ensure successful crop growth, high operational costs, significant maintenance, space consumption, and a lengthy project duration.

Do all plants grow better in a greenhouse?

Greenhouses are a powerful tool for boosting plant growth by providing a controlled environment. They shield your garden from the unpredictable outside world, ensuring each plant receives the necessary care to thrive. This tailored care creates a healthier, lusher, and more productive environment. The greenhouse effect is primarily achieved through temperature regulation. In winter, greenhouses capture sun’s warmth, while in summer, ventilation and shading cool things down. This consistent environment supports healthy growth and reduces stress on plants.

Can you grow flowers in a greenhouse year round?

A greenhouse is a dream for gardeners, allowing them to grow flowers, herbs, and vegetables year-round. With proper planning, greenhouses can be a beautiful oasis, allowing plants to thrive in different seasons. Spring is an exciting time for greenhouse gardeners, as it’s ideal for cool-weather annuals, blooming bulbs, and hardy perennials. Start preparing early by clearing dead growth and turning over the soil, then mix in compost or fertilizer to replenish nutrients.

Popular annuals for spring planting include snapdragons, stocks, calendulas, violas, cheerful pansies, flowering bulbs like tulips, daffodils, and hyacinths, and perennials from seed or young plants like foxgloves, columbines, and veronicas.

Summer is a challenging season for greenhouse gardeners, but it can thrive with careful management. Proper ventilation, shade control, and irrigation are critical. Open doors, windows, and vents on very hot days to allow excess heat to escape and prevent plants from getting scorched. Install shade cloth, greenhouse paint, or window treatments to filter intense sunlight. Add fans to improve air circulation.

Colorful annuals like Zinnias, marigolds, petunias, geraniums, and tropical plants like mandevilla, hibiscus, and orchids thrive in summer. Monitor soil moisture closely and water early daily to avoid foliar diseases. For plants that prefer a humid environment, misting and gravel trays can help increase humidity.

Can you grow in a greenhouse all summer long?

To protect your plants from summer heat, ensure good ventilation and avoid overheating the greenhouse. Keep heat-loving plants like beans and squashes inside the greenhouse all summer. Choose a sturdy greenhouse made of high-quality steel with a waterproof cover to ensure longevity. Select the right plants for the season, starting with hardy, easy-to-grow plants for new year-round greenhouse growers.

Use the right soil, including high-quality gardening soil and compost or manure, as recommended for the types of crops you plan to grow. This will help prevent damage to your plants and allow you to adjust as you grow. Remember to choose the right greenhouse for your needs and budget.
