How to Grow Winter Lettuce in a Winter Gardenz Greenhouse
Enjoy fresh, crisp lettuce year-round—even during Australia’s cooler months—by growing in a Winter Gardenz greenhouse equipped with a Frost Guard heater. This setup ensures optimal growing conditions for cool-season crops like lettuce, even in winter.
Start by selecting cold-tolerant lettuce varieties such as Winter Density, Arctic King, and Rouge d’Hiver. Maximise your growing space by adding greenhouse shelving and planting in potting bags for elevated airflow and drainage.
Maintaining a stable temperature is key. The Winter Gardenz Frost Guard heater features automatic thermostat control and a built-in fan to evenly distribute warmth—keeping your greenhouse cosy even on frosty nights. In summer, switch to fan-only mode to improve air circulation and reduce humidity.
Prepare your soil with compost or organic matter to ensure it’s loose, well-draining, and nutrient-rich. For successful germination, keep seedlings between 25–30°C. If ambient temperatures are too low, use a heat mat to give your lettuce a strong start.
Once established, maintain consistent moisture, apply organic fertiliser as needed, and monitor for pests or fungal issues. With the right care, winter lettuce cultivation in your greenhouse is a simple and rewarding way to enjoy homegrown greens throughout the season.
