In Northern Ireland, sow aubergine seeds indoors from late January to early March. Use a heated propagator or place trays in a warm, sunny indoor spot where temperatures stay around 21–24°C. This early sowing ensures a long enough season before cooler autumn weather arrives.
Transplant young aubergine plants in mid to late June once the risk of frost is gone and night temperatures stay above 10°C. Outdoor planting is not generally recommended. Instead, opt for a greenhouse, polytunnel, or conservatory to give your plants the warmth they need.
Grow aubergines in containers or raised beds filled with rich, free-draining compost. Place them in a sheltered, sunny position under cover. Water consistently, support the stems as they develop, and feed weekly with a high-potash fertiliser once flowering starts. Ventilate well to reduce humidity-related issues.
Yes — but only under protection. The climate in Northern Ireland is too cool and damp for outdoor aubergines. Greenhouses or tunnels are essential to ensure sufficient heat, especially during fruiting. With care, it's entirely possible to get a successful crop.
