1. Why choose a greenhouse in South Africa?

By creating a warmer, protected microclimate, a greenhouse lets you start seedlings earlier and keep harvesting later. Inside, sheltered growing conditions can encourage growth and help protect tender plants from cold snaps, even without additional heating.

2. Choose your Bloomcabin greenhouse

• Size : from 8 m² (2 × 4 m) to 14 m² (3 × 5 m).
• Frame : sturdy aluminium profiles, rust-resistant and weather-resistant.
• Glazing : 4 mm toughened glass for excellent light and safety.
• Ventilation : roof vents, sliding doors and integrated gutters.
• Warranty : 12 years; delivery in 3–4 weeks.

Ideal for growing across the seasons. Explore the range: Bloomcabin aluminium greenhouses.

3. Install your greenhouse

• Choose a sunny position with at least 6 hours of light daily.
• Position the door for practical access and use a wall or hedge as wind protection where appropriate.
• Build the greenhouse on a level base, such as a slab or compacted gravel.

4. Prepare the growing medium

Use an open mix of growing medium, compost and perlite. Avoid heavy or pest-infested garden soil. Choose containers at least 30 cm deep for crops such as tomatoes and cucumbers.

5. What to plant first

• Tomatoes, peppers and cucumbers, including bush or dwarf varieties.
• Lettuce, rocket and spinach are quick and forgiving.
• Herbs: basil, parsley and mint.
• Microgreens: harvest in 1–3 weeks, useful in cooler months.
• Flowers such as nemesia, cosmos or dianthus add colour.

6. Water efficiently

• Water deeply, but only when the soil surface feels dry.
• Add drip irrigation with a timer for consistency.
• Collect rainwater through Bloomcabin gutters for more sustainable watering.
• Use mulch to retain moisture.

7. Manage the climate

• Ventilate once temperatures rise above 22 °C; open vents and doors.
• Use 30–50% shade cloth over the sides during hot weather.
• In winter, use bubble wrap or an insulating cover and add a small thermostatic heater if needed.
• A small solar fan can help maintain air movement.

8. Protect against pests

• Inspect regularly for aphids, red spider mites and mildew.
• Use yellow traps to catch flying insects.
• Try companion planting with deterrent plants such as basil or marigolds.
• Consider biological controls such as ladybirds or nematodes where appropriate.
• Clean tools and pots between crops with soapy water or a mild solution.

9. Fertilise appropriately

Follow the South African product label. Where suitable, apply a 10-10-10 NPK fertiliser every 2–3 weeks during early growth, then change to 5-10-5 or a fruit-and-vegetable feed. Seaweed extracts or compost tea may also support soil health.
