Aubergine (eggplant) is a warm-weather crop known for its glossy, deep-purple fruits and versatile culinary uses. While it requires a bit more warmth and patience compared to other vegetables, growing aubergines can be incredibly rewarding.
Your soil, climate, and care methods will influence your success, so use this guide as a flexible foundation and adjust as needed to find what works best in your garden.
Choosing the Right Aubergine Variety
Aubergines come in a range of shapes, sizes, and colors–from traditional purple to white, green, and even striped varieties.
Popular Varieties:
- Black Beauty: Classic, large, deep-purple fruits that are perfect for grilling and roasting.
- Listada de Gandia: Striped, purple-and-white fruits with a mild flavor.
- Little Fingers: Small, slender aubergines that grow in clusters and are quick to mature.
- Rosa Bianca: Round, Italian heirloom variety with a delicate, creamy texture.
Tip: Try growing different varieties to discover which ones thrive in your garden and suit your culinary needs.
Preparing the Soil
Aubergines thrive in fertile, well-draining soil that retains moisture without becoming waterlogged.
Basic Soil Guidelines:
- Add compost or aged manure to enrich the soil.
- Aim for a slightly acidic to neutral pH (6.0 to 7.0).
- Ensure good drainage to prevent root rot.
Experiment: Warm the soil by using black plastic mulch, especially if you live in a cooler climate.
Planting Your Aubergines
- Starting from Seeds:
- Start seeds indoors 8 to 10 weeks before the last frost. Aubergines require warm soil to germinate, ideally around 24C (75F).
- Transplant seedlings outdoors after the last frost when nighttime temperatures remain above 13C (55F).
- Spacing and Depth:
- Plant seedlings 60 cm (24 inches) apart in rows spaced 75 to 90 cm (30 to 36 inches) apart.
- Sunlight Needs:
- Aubergines need full sun–at least 6 to 8 hours per day.
- Aubergines need full sun–at least 6 to 8 hours per day.
Caring for Your Aubergines
- Watering: Keep the soil consistently moist but not soggy. Aubergines need about 2.5 cm (1 inch) of water per week.
- Mulching: Apply mulch to retain moisture and regulate soil temperature.
- Fertilizing: Feed with a balanced fertilizer every few weeks, especially when plants start flowering.
Observation Tip: If your aubergines produce flowers but no fruit, it may be due to poor pollination. Encourage bees and other pollinators by planting flowers nearby.
Harvesting Your Aubergines
Aubergines are typically ready to harvest 70 to 90 days after transplanting, depending on the variety.
How to Harvest:
- Harvest when the fruits are glossy and firm, before the skin becomes dull and seeds harden.
- Use a sharp knife or pruners to cut the fruit from the plant, leaving a small stem attached.
Try it and see: Experiment with harvesting at different stages–younger aubergines tend to be more tender and less bitter.
Storing Aubergines
Proper storage helps maintain the freshness and flavor of aubergines.
How to Store Aubergines:
- Short-Term Storage: Store aubergines at room temperature in a cool, dry place and use within 3 to 5 days.
- Refrigeration: If you must refrigerate, store in the vegetable crisper for no more than a few days to prevent chilling damage.
- Freezing: Slice and blanch aubergines before freezing in airtight containers for longer storage.
Tip: Aubergines are best enjoyed fresh, as they can become bitter and spongy over time.
Common Aubergine Growing Problems
- Blossom End Rot:
- Caused by calcium deficiency or inconsistent watering. Keep the soil evenly moist and ensure proper nutrient balance.
- Flea Beetles:
- Tiny black beetles that chew small holes in leaves. Use row covers and introduce beneficial insects to control them.
- Poor Fruit Set:
- Often due to lack of pollination or temperatures that are too cold or hot. Hand-pollinate if needed.
- Often due to lack of pollination or temperatures that are too cold or hot. Hand-pollinate if needed.
