How to Grow Aubergines in the UK

Step 1: Starting Aubergine Seeds

1. Timing: Start seeds indoors 8-10 weeks before the last frost date (typically late February to early March).
2. Containers: Use seed trays or small pots filled with a lightweight seed-starting mix.
3. Planting Depth: Sow seeds 1/4 inch deep and cover lightly with soil.
4. Warmth: Maintain a soil temperature of 20-25°C (68-77°F) using a heating mat if needed.
5. Light: Provide 12-16 hours of bright light daily using grow lights or a sunny windowsill.

Germination Time: Seeds usually sprout in 7-14 days.

Step 2: Transplanting Seedlings

1. Timing: Transplant seedlings into larger pots when they have 2-3 sets of true leaves.
2. Hardening Off: Gradually acclimate seedlings to outdoor conditions over 7-10 days.
3. Spacing: Space plants 18-24 inches apart in garden beds or one plant per pot for containers.

Step 3: Choosing the Right Growing Location

1. Greenhouses or Polytunnels: Provide consistent warmth and protect plants from the UK’s unpredictable weather.
2. Sunny Garden Beds: Select a sheltered spot with at least 6-8 hours of direct sunlight daily. Use cloches or fleece for added protection.
3. Containers: Use pots at least 12-18 inches deep for better root growth and mobility.

Step 4: Watering and Feeding

1. Watering: Keep the soil consistently moist but not waterlogged. Water deeply in the morning.
2. Feeding: Start feeding with a balanced fertilizer once plants are established. Switch to a potassium-rich fertilizer during flowering and fruiting.

Step 5: Supporting Aubergine Plants

1. Stakes or Cages: Install supports early to prevent plants from toppling as they grow.
2. Tying Stems: Secure stems gently to supports with soft ties for stability.

Step 6: Pollination and Fruit Development

1. Pollination: In greenhouses, hand-pollinate flowers by gently tapping them or using a soft brush.
2. Encourage Pollinators: Plant companion flowers like marigolds or lavender nearby to attract bees.

Step 7: Harvesting Aubergines

1. Ripeness: Harvest when fruits are glossy, firm, and have reached their mature size.
2. Harvesting Method: Use a sharp knife or pruners to cut fruits, leaving a short stem attached.
3. Regular Picking: Frequent harvesting encourages the plant to produce more fruits.

Common Challenges and Solutions

Cool Temperatures

• Problem: Slows growth and fruit development.
• Solution: Use greenhouses, polytunnels, or cloches to maintain warmth.

Blossom-End Rot

• Problem: Caused by inconsistent watering or calcium deficiency.
• Solution: Water regularly and add calcium-rich amendments to the soil.

Pests

• Problem: Aphids, spider mites, and whiteflies may infest plants.
• Solution: Use neem oil, insecticidal soap, or companion planting to deter pests.

Tips for Thriving Aubergines in the UK

3. Protect from Frost: Be prepared to cover plants during unexpected cold snaps.
