In A Greenhouse, What Exotic Plants Can I Grow?

Growing exotic plants in a greenhouse can be a rewarding experience for gardeners. With the right combination of temperature, humidity, and light, tropical and sub-tropical plants have their own diverse requirements when it comes to soil, sun, shade, watering, and more. Some popular plants that thrive within greenhouse environments include Orchids, Venus Fly Traps, African Violets, Geraniums, and Poinsettias.

Dragon fruit is a popular choice for those who don’t believe in love at first sight. However, simply putting tender plants inside a greenhouse doesn’t guarantee success. Tropical and sub-tropical plants have their own diverse requirements when it comes to soil, sun, shade, watering, and more. Echinocereus are generally excellent choices for greenhouses, while Thai Red Roselle is also an excellent choice.

Two other exotic and unusual plants to consider growing in your greenhouse are Bougainvillea, Kumquat, Night-Blooming Jasmine, and Citrus reticulata ‘Kinnow’. Keeping plants happy inside the greenhouse is a lot of work, but tropical plants perform pretty well once brought inside and repotted. Container avos and citrus are short enough to be grown in a greenhouse, with a range of 5-10 feet depending on pruning preferences.

Orchids, succulents, caladiums, zebra plants, begonias, and ferns are also suitable for greenhouse gardens. Passion fruit vines are a unique and exotic addition to your greenhouse, producing distinctive, aromatic fruits.

What is the disadvantage of greenhouse?

The greenhouse effect, which is caused by human activities, results in soil erosion, which in turn destroys fertile land, decreases crop yield, and contributes to global warming. Furthermore, it gives rise to climatic alterations, including the elevation of water levels, which inflict damage upon marine life and aquatic ecosystems. It is therefore imperative to take action to mitigate the effects of this phenomenon.

What plants are best to grow in a greenhouse?

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 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.

Can a greenhouse get too hot for plants?

The sun’s powerful rays can penetrate glass and other manmade materials, damaging plants in greenhouses. Without proper ventilation, shade, or other cooling methods, plants will overheat, damaging their leaves and fruits while drying out the soil. To keep your greenhouse cool in summer, use ventilation as one of the best and most natural ways to keep it cool. It is also important during spring and autumn months when the sun is still powerful. The right type of ventilation will allow you to control the temperature in your greenhouse and provide the necessary warmth for your plants.

What temperature is too cold for a greenhouse?

To maintain optimal plant growth, keep your greenhouse temperature below 3C (37F). Tender plants like pelargoniums, half-hardy fuchsias, and citrus trees prefer a minimum of 7C (45F), and safest at 10C (50F). This temperature is ideal for young plants and plug plants. If you have a conservatory, use it to overwinter delicate plants. Position heaters carefully, placing them in an open, central spot away from water and angling the heater to prevent foliage desiccation by direct airflow above nearby plants.

Can you keep plants in a greenhouse all summer?

In late spring, many gardeners plant seedlings in open ground, but it’s essential to use a greenhouse year-round to create an optimal microclimate for plants. The key is to use the summer greenhouse correctly to control the climate conditions, such as darkening with shade cloth, ventilating during the hottest days, protecting plants from high winds and rain, and maintaining humidity levels.

During summer, plants may experience significant stress due to weather changes such as storms, unexpected temperature drops, drought, or prolonged rains. To control these conditions, use shade cloth, ventilate continuously, protect plants from high winds and rain, and maintain humidity levels. Additionally, weeds will be less of a problem as they grow more reluctant and pests will be less likely to invade.

In summary, using a greenhouse in the summer is beneficial for maintaining an optimal microclimate for plants, avoiding significant stress from weather changes, and ensuring the health and growth of your plants.

Can plants get too much sun in a greenhouse?

Sunlight is crucial for plant growth, providing nutrients to shrubbery and flowering plants. However, too much sunlight can be harmful to plants. Greenhouses regulate the amount of sunlight and interior temperature to create an ideal environment for plants. One danger is harmful ultraviolet light, which plants use as a catalyst for photosynthesis. This process converts water, minerals, and carbon dioxide into oxygen using ultraviolet rays. However, an overabundance of ultraviolet light can damage plants, as it overwhelms the internal system responsible for photosynthesis.

Constant and overwhelming amounts of ultraviolet energy run down plant systems, preventing them from efficiently processing elements involved in photosynthesis. This can have adverse effects on the long-term health of plants, as they cannot nourish themselves properly. To protect plants from harmful ultraviolet light, greenhouses should use window shades to regulate the amount of sunlight and interior temperature.

Why do greenhouses fail?

Greenhouse issues can be managed by changing air filters regularly, controlling temperature swings, and maintaining existing heating systems. Overly hot greenhouses can be controlled with shade cloth or a greenhouse whitewash. Irrigation and fertigation systems can be addressed by timely repair or replacement of defective equipment, flushing systems with hydrogen peroxide and water solution, and cleaning drippers with a hydrogen peroxide and water solution.

Mold issues can encourage pests and diseases, necessitating system disinfection after each harvest using a water and hydrogen peroxide mix. Fertilizer salt accumulation in fertigation lines can cause nutrient solution spikes in electrical conductivity, so regular inspection and cleaning are essential. If crops seem dehydrated, inspect water, timing, and cycle controls for clogs or failures to prevent under or over watering.
