    Herbs 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 thrive in the warm and protected environment of a greenhouse. You can enjoy vine-ripened tomatoes earlier in the season.

    The warm and protected conditions allow you to extend the growing season and enjoy fresh tomatoes earlier in the year.

    Choose determinate varieties for compact spaces and indeterminate varieties if you have more room. Proper spacing, sturdy trellising, and good ventilation are essential for healthy tomato growth. Regular pruning and removing suckers encourage better airflow and fruit production. With consistent care, ample sunlight, and proper watering, your greenhouse tomatoes can yield juicy and flavorful harvests throughout the seasons.

    Lettuce and Leafy greens

    Lettuce, spinach, and Swiss chard flourish in a greenhouse’s controlled conditions. These fast-growing crops can provide you with a constant supply of fresh greens.

    Leafy greens are ideal candidates for greenhouse cultivation, offering a year-round supply of nutritious and flavorful produce. Spinach, lettuce, kale, and Swiss chard thrive in a controlled environment, protected from harsh weather and pests.

    Greenhouse-grown greens tend to be more tender and vibrant due to the consistent conditions. Use raised beds or containers with well-draining soil and ensure adequate spacing to prevent overcrowding.

    Employ shade cloth during peak sunlight to avoid heat stress. Regular monitoring of moisture levels and proper ventilation are crucial. With a little attention and care, you can enjoy a continuous supply of fresh, home-grown leafy greens straight from your greenhouse.


    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.

    The vibrant hues of radishes, ranging from red and pink to white, bring a lively touch to your greenhouse beds. Their crisp texture and peppery taste make them a versatile ingredient in salads, sandwiches or enjoyed fresh with a dash of salt. Radishes, being relatively low-maintenance, are an ideal starting point for greenhouse enthusiasts looking to witness the fruits of their labour without an overly complex cultivation process.

    As you embark on your greenhouse gardening journey, experimenting with radishes can be a joyful introduction to the world of home cultivation. Their speedy growth and vibrant presence make them a delightful addition to any greenhouse, promising a satisfying harvest for beginners and seasoned gardeners alike.
