In this guide, we’ll explore growing tips, recipes, and where to find green tomatoes in the UK.

What Are Green Tomatoes?

Green tomatoes can be either:

1. Unripe Red Tomatoes: Tomatoes harvested before they ripen. These are often used towards the end of the growing season in the UK when colder weather halts ripening.
2. Naturally Green Varieties: Tomatoes that remain green when fully ripe, such as ‘Green Zebra’ or ‘Aunt Ruby’s German Green.’

Why Are Green Tomatoes Popular in the UK?

Green tomatoes are cherished for several reasons:

• Seasonal Necessity: UK gardeners often harvest green tomatoes late in the season to avoid frost damage.
• Unique Flavour: Their tartness adds depth to recipes.
• Versatility: Perfect for frying, pickling, chutneys, and more.
• Sustainability: Using green tomatoes reduces waste, ensuring all fruits are utilised.

How to Grow Green Tomatoes in the UK

Growing green tomatoes in the UK’s cooler climate requires a bit of planning, especially for late-season harvesting.

2. Start Indoors

• Use seed trays and keep the soil warm (18-21°C) for optimal germination.

3. Transplant Outdoors

• Transplant seedlings after the last frost into well-drained, nutrient-rich soil.
• Use grow bags or containers for flexibility in cooler regions.

4. Support and Prune

• Stake or cage plants to support growth and prune lower leaves for better airflow.

5. Harvest Before Frost

• As temperatures drop in autumn, pick green tomatoes to prevent frost damage.
