Greenhouse Gardening for Beginners: Where Do I Start?

Gardening has always been a fulfilling and rewarding hobby, but for beginners, the thought of starting a greenhouse can be a bit overwhelming. However, with the right guidance and a bit of enthusiasm, anyone can embark on the journey of greenhouse gardening. In this article, we'll break down the basics of greenhouse gardening for beginners, providing a step-by-step guide to help you get started.

Why Choose Greenhouse Gardening?

Before delving into the practicalities, let's understand why greenhouse gardening is gaining popularity among both seasoned gardeners and beginners alike.

  1. Extended Growing Season

Greenhouses create a controlled environment, allowing you to extend your growing season beyond the limitations of outdoor gardening. This means you can enjoy fresh produce and vibrant flowers throughout the year.

  1. Protection from Weather Extremes

Weather can be unpredictable, with sudden frosts, heavy rains, or scorching heat damaging your plants. A greenhouse acts as a shield, protecting your plants from adverse weather conditions and providing a stable climate for optimal growth.

  1. Pest Control

Greenhouses offer a barrier against pests and diseases that can harm your plants. This controlled space makes it easier to manage and prevent infestations, reducing the need for pesticides.

  1. Customisable Environment

One of the key advantages of greenhouse gardening is the ability to control the environment. You can adjust temperature, humidity, and light levels to meet the specific needs of your plants, resulting in healthier and more productive crops.

Step 1: Choose the Right Greenhouse

The first and most crucial step in greenhouse gardening is selecting the right structure. Consider the following factors when making your choice:

  1. Size

Choose a greenhouse size that suits your available space and gardening needs. A small greenhouse is ideal for beginners, as it's easier to manage and requires less maintenance.

  1. Material

Greenhouses come in various materials, such as glass, polycarbonate, and polyethylene. Each has its advantages, with glass providing better light transmission and durability, while polycarbonate offers insulation.

  1. Location

Select a location with ample sunlight for your greenhouse. South-facing positions receive the most sunlight throughout the day, promoting optimal plant growth.

  1. Ventilation

Proper ventilation is essential to regulate temperature and humidity inside the greenhouse. Look for models with roof vents or side vents to ensure good air circulation.

Step 2: Prepare the Site

Once you've chosen your greenhouse, it's time to prepare the site for installation.

  1. Level the Ground

Ensure that the ground is level and firm where you plan to set up your greenhouse. This provides stability and prevents water from pooling around the structure.

  1. Install a Foundation

Depending on your greenhouse type, you may need to install a foundation. This could be a simple perimeter base or a full concrete foundation. Follow the manufacturer's guidelines for the specific greenhouse model you've chosen.

  1. Consider Drainage

Good drainage is essential to prevent waterlogging. If your greenhouse is placed on soil, consider adding gravel or a drainage system to improve water runoff.

Step 3: Choose the Right Plants

With your greenhouse in place, it's time to decide what to grow. As a beginner, start with plants that are relatively easy to care for and have similar growing requirements.

  1. Herbs

Herbs like basil, thyme, and mint are excellent choices for beginners. They don't require a lot of space, and their aromatic leaves can be used in cooking.

  1. Salad Greens

Lettuce, spinach, and kale are fast-growing and well-suited for greenhouse conditions. They're also versatile ingredients for salads and sandwiches.

  1. Tomatoes

Tomatoes thrive in the controlled environment of a greenhouse. Choose compact varieties for smaller spaces and enjoy a bountiful harvest.

  1. Flowers

Consider adding flowering plants like marigolds or petunias for a touch of colour. Flowers not only beautify your greenhouse but also attract beneficial insects.

Step 4: Provide Proper Care

Once your greenhouse is set up and plants are in place, it's time to focus on care and maintenance.

  1. Watering

Establish a regular watering schedule, keeping in mind the specific needs of your plants. Greenhouse-grown plants may require more frequent watering than outdoor ones.

  1. Temperature Control

Monitor the temperature inside your greenhouse, especially during extreme weather conditions. Ventilate when necessary and consider adding shading during hot summer months.

  1. Humidity Management

Maintain proper humidity levels by watering the floor or using a humidifier. This is particularly important for plants that thrive in tropical conditions.

  1. Pest Monitoring

Regularly check your plants for signs of pests. Early detection allows for prompt intervention, reducing the risk of infestations spreading.

Step 5: Learn the Basics of Greenhouse Gardening

To become a successful greenhouse gardener, it's essential to familiarise yourself with some fundamental concepts.

  1. Soil and Potting Mixes

Selecting the right soil is crucial for greenhouse gardening. Use well-draining potting mixes tailored to the needs of your specific plants.

  1. Fertilisation

Understand the nutritional requirements of your plants and fertilise accordingly. Greenhouse plants often benefit from a balanced liquid fertiliser.

  1. Pruning and Training

Learn the art of pruning to encourage healthy growth and improve air circulation. Some plants, like tomatoes, may require staking or training to support their growth.

  1. Disease Management

Be proactive in preventing diseases by practising good hygiene and regularly inspecting your plants. Remove any affected leaves promptly and consider using organic fungicides if necessary.

Step 6: Embrace the Learning Curve

Greenhouse gardening, like any skill, involves a learning curve. Don't be discouraged by initial challenges; instead, view them as opportunities to refine your gardening skills.

  1. Keep a Journal

Maintain a gardening journal to record your observations, successes, and challenges. This will serve as a valuable reference for future seasons.

  1. Seek Advice

Join gardening communities, both online and locally, to exchange tips and advice with experienced greenhouse gardeners. Learning from others' experiences can be immensely beneficial.

  1. Experiment

Don't hesitate to experiment with different plants, growing techniques, and greenhouse accessories. This hands-on approach will deepen your understanding of greenhouse gardening.

  1. Enjoy the Process

Above all, enjoy the process of greenhouse gardening. Witnessing the growth and development of your plants is a rewarding experience that connects you to nature and the food you eat.


Embarking on greenhouse gardening as a beginner may seem daunting, but by breaking down the process into manageable steps, you can set yourself up for success. From choosing the right greenhouse to caring for your plants and embracing the learning curve, each step contributes to a fulfilling and enjoyable gardening experience. So, roll up your sleeves, dig into the soil, and watch your greenhouse flourish with life and vibrant greenery. Happy gardening!
