Our tips for building a greenhouse garden in Perth
In Perth, where the climate can swing from hot, dry summers to wet, mild winters, a greenhouse offers an ideal solution for gardeners looking to extend their growing season and protect sensitive plants from extreme weather.
Building a greenhouse in Perth not only provides a controlled environment for cultivating a wide range of plants, but also turns into a rewarding hobby for gardening enthusiasts.
Here’s how you can set up and maintain a greenhouse that thrives in Perth’s unique conditions.
#1 Choosing the right greenhouse
Selecting the structure: The type of greenhouse you choose depends on the space available, your budget, and what you plan to grow. Options range from simple cold frames to elaborate glass structures. Polycarbonate panels are popular due to their durability, excellent light diffusion, and insulation properties.
Orientation and location: Position your greenhouse to maximise light exposure, ideally with a north-south orientation to ensure consistent sunlight throughout the day. Ensure it’s sheltered from strong winds and has access to water and electricity if needed.
#2 What to grow in your greenhouse
Vegetables 365 days of the year: A greenhouse allows you to grow vegetables like tomatoes, capsicums, and leafy greens even out of season. These plants benefit from the stable temperatures and protection from pests that a greenhouse provides.
Exotic plants and orchids: Take advantage of the controlled environment to cultivate exotic plants that would otherwise struggle in Perth’s climate. Orchids, ferns, and tropical flowers can thrive under glass, providing colour and vibrancy to your greenhouse.
Starting seedlings: Use your greenhouse to get a head start on the spring planting season by starting seedlings early. This can be particularly advantageous for longer-growing season crops that need more time to mature.
#3 Creating optimal growing conditions
Temperature control: Managing the internal temperature of your greenhouse is crucial, especially during Perth’s hot summers. Ventilation is key; ensure your greenhouse is equipped with vents or windows that can be opened to regulate heat. During cooler months, a heater may be necessary to maintain a steady temperature.
Humidity and watering: Greenhouses naturally retain more humidity than outdoor environments, which can be a boon for many plants. However, it’s important to monitor humidity levels to prevent mould and mildew growth. Installing a hygrometer to measure humidity and adjusting your watering schedule accordingly will help maintain the optimal environment.
Shading and cooling: To prevent overheating in summer, consider using shade cloths that can be rolled down during the hottest part of the day. Additionally, a small fan can help circulate air and keep temperatures consistent throughout the space.
#4 Maintenance and care
Regular cleaning: Keeping your greenhouse clean is essential to prevent the spread of diseases and pests. Regularly clean the glass or polycarbonate panels to ensure maximum light penetration. Sweep out plant debris and disinfect pots and trays periodically.
Pest management: Even in a controlled environment, pests can be a problem. Regularly inspect your plants for signs of infestation. Natural pest control methods, such as introducing beneficial insects like ladybugs or using neem oil, can effectively manage pests without the need for harsh chemicals.
Routine checks: Regularly check the structure for any damage, especially after extreme weather events. Ensure that all vents and doors are functioning properly and that the sealants are intact to keep the environment sealed and insulated.
