    Gardening NeedsHerbs and Microgreens

    Start your greenhouse journey with herbs like basil, mint, and parsley. Their compact size makes them ideal for greenhouse cultivation. Microgreens, such as kale, radishes, and sunflower shoots, are nutrient-dense and can be harvested within weeks.

    You can get started with growing herbs even in a mini greenhouse which is cost-effective and provides you with the appropriate controlled environment to grow herbs and take it to the next level.


    Tomatoes grow well in a greenhouse because of its warm, cozy atmosphere.

    You may enjoy fresh tomatoes early in the year and increase the growth season using a greenhouse.

    For tomatoes to grow healthily, proper spacing, strong trellising, and adequate ventilation are necessary. Better ventilation and fruit production are encouraged by routine pruning and sucker removal. Growers may harvest tasty, juicy tomatoes all year long with regular attention, lots of sunlight, and appropriate irrigation.

    Lettuce and Leafy greens

    Under the carefully regulated conditions of a greenhouse, lettuce, spinach, and Swiss chard thrive. These fast-growing plants can give you a regular supply of fresh greens.

    Greenhouse is a great option for leafy greens since it provides a year-round source of tasty and nutritious vegetables. Protected from inclement weather and pests, Swiss chard, spinach, lettuce, and kale grow well in a regulated environment.

    Because of the constant circumstances, greens grown in greenhouses are typically more tender and colourful. To avoid overpopulation, use raised beds or containers with soil that drains properly and make sure there is enough space between plants.

    To prevent heat stress, use shade cloth when the sun is at its strongest. Ensuring adequate ventilation and regular monitoring of moisture levels are essential. You can have a steady supply of fresh, home-grown leafy greens with a little nurturing.


    Cucumbers are prolific climbers and can be trained vertically in a greenhouse, saving space while producing an abundance of crisp cucumbers.

    Cultivating cucumbers in a greenhouse provides an advantageous environment for their growth and yield. The controlled conditions allow for consistent warmth, humidity, and protection against external factors. With trellises or supports, vertical growth can be encouraged, optimising space utilisation.

    Greenhouses facilitate the prevention of common cucumber issues like pests and diseases, resulting in healthier plants. Regular pruning and pollination are more manageable in this setting, leading to higher fruit production. Whether you’re growing slicing cucumbers or pickling varieties, greenhouse cultivation offers extended growing seasons and a higher likelihood of successful, bountiful harvests, allowing you to enjoy fresh cucumbers throughout the year.


    Capsicums, with their vibrant colours and sweet flavours, are a fantastic choice for beginners venturing into greenhouse gardening in Australia. Here’s a concise guide to help you cultivate these delightful peppers:

    Select capsicum varieties that are well-suited for greenhouse cultivation. Popular choices include the classic California Wonder or the richly hued Sweet Chocolate. These varieties are known for thriving in controlled environments, making them ideal for greenhouse setups.

    Ensure your greenhouse receives an abundance of sunlight, as capsicums love sun-soaked conditions. Select a sunny spot within your greenhouse to promote robust growth. Maintain a temperature range of 20-25°C for optimal development.

    Capsicums prefer well-draining soil enriched with organic matter. A slightly acidic to neutral pH level (6.0-6.8) is ideal. Use a high-quality potting mix to provide the necessary nutrients for healthy growth.

    Start capsicum seeds indoors about 8-10 weeks before the last frost date. Once seedlings are robust, transplant them into larger containers or directly into the greenhouse soil. Consistent moisture is key; implement a drip irrigation system to keep the soil evenly moist.

    Encourage bushier growth by pinching out the tips when plants reach around 20 cm in height. Additionally, provide adequate support for branches laden with developing fruit to prevent breakage.

    Peppers and Chillies

    Whether sweet or spicy, peppers and chillies appreciate the consistent warmth and protection from a greenhouse. They can be a colourful and flavorful addition to your home-grown produce.

    Growing peppers and chillies in a greenhouse offer a controlled environment that enhances their growth and productivity. With the ability to regulate temperature, humidity, and sunlight exposure, greenhouse cultivation ensures optimal conditions for these heat-loving plants.

    This approach extends the growing season, allowing for multiple harvests. Peppers and chillies thrive in well-drained soil, and greenhouse settings provide an ideal platform to maintain the necessary moisture levels. Additionally, protection from outdoor pests and adverse weather conditions fosters healthier plants. Whether you’re cultivating mild bell peppers or fiery chillies, a greenhouse offers a tailored space to nurture these vibrant and flavorful additions to your culinary endeavours.


    Adding a burst of colour and flavour to your greenhouse, radishes are an excellent choice for those new to gardening. Their quick growth and versatility make them a favourite among beginners.
