Aubergines are potted on a few weeks after sowing, once young plants are sufficiently developed. This operation gives them more space before final planting in vegetable patch or in a container.
Potting on aubergines: key steps
| Step | When? | Conditions |
|---|---|---|
| Potting on into pots | 3 to 4 weeks after sowing | 2 to 4 true leaves |
| Final planting | After last frosts | Above 15 °C |
| Establishment in open ground | Following weeks | Regular watering and mulch recommended |
Why pot on aubergines?
Young aubergines grow quickly and soon become cramped after sowing. Potting on aubergine plants allows them to continue growing in better conditions. This step helps to:
- strengthen root system
- avoid competition between plants
- encourage steady growth
- produce stockier, tougher plants
When to pot on aubergines?
Right time is when seedlings develop first true leaves and a sturdy stem, generally 3 to 4 weeks after sowing aubergine seeds.
Under cover: between March and April
After sowing in seed trays or cells, pot on seedlings into individual pots as soon as they start to touch or run out of space.
Final planting: from May
Plant aubergines in open ground or in a large container only after last frosts, when temperatures remain consistently above 15 °C, usually between mid‑May and early June depending on region.
? Aubergines are very sensitive to cold, so it is better to wait a few extra days than to plant too early.
How to pot on aubergines?
Required equipment:
- individual pots
- good potting compost (for sowing or potting on)
- well‑rotted compost
- dibber or spoon
- watering can with fine rose
Step 1: pot seedlings into individual pots
Potting on into pots mainly concerns sowings made in seed trays.
- Prepare pots filled with a light potting compost
- Carefully lift each seedling without breaking roots
- Make a hole with a pencil or dibber
- Pot on aubergine plants without burying stem further
- Firm gently then water
- Keep aubergines in light and warmth, ideally between 18 and 22 °C.
? Young plants continue growth under cover for several weeks before moving outside.
Step 2: plant aubergines in open ground
When temperatures are mild enough, aubergines can go to vegetable patch or into a large container.
- Work soil to loosen
- Add compost to enrich soil
- Water pots before planting
- Plant with spacing of 50 to 60 cm
- Set rootball level with soil
- Water generously after planting
Plants may temporarily wilt after transplanting: they quickly regain vigour with warmth and regular moisture.
How to help aubergines recover well?
- Keep soil lightly cool with regular watering
- Mulch around plants to retain warmth
- Protect aubergines from cold nights if necessary
- Install a stake to support future crops
? Aubergines particularly appreciate warm, sunny, sheltered positions.
