Aubergines growing in pots in a garden

Growing aubergines, or eggplants as they're known in other parts of the world, can be a rewarding venture, especially when done in containers. With a little care and attention, you can enjoy fresh aubergines from your own garden.

Quick Answer

To grow aubergines in containers, choose a sunny spot, use a pot at least 30cm in diameter, and keep the soil consistently moist. Start seeds indoors in early spring and transplant after the last frost.

Choosing the Right Container

When it comes to growing aubergines in containers, size matters. Aim for a pot that's at least 30cm in diameter and depth. This gives the roots ample space to grow and supports the tall stems of the plant.

Grow bags can also be a great option, especially if you're limited on space. They offer good drainage and are easy to move around to capture the best sunlight.

Soil and Compost

Using the right soil mix is crucial. Aubergines thrive in well-draining, nutrient-rich soil. we recommend a mix of multi-purpose compost with added perlite for drainage.

  • Use multi-purpose compost for a nutrient-rich base
  • Add perlite to improve drainage
  • Consider adding a slow-release fertiliser for consistent nutrition

Planting and Timing

In Staffordshire, I start my aubergine seeds indoors around late February to early March. Aubergines need warmth to germinate, so a heated propagator can be a real asset.

Once the risk of frost has passed, usually by mid-May here in the Midlands, you can transplant your seedlings into their final containers. Ensure they have a sunny spot, as aubergines thrive with at least 6-8 hours of sunlight daily.

February-March Start seeds indoors Use a heated propagator
May Transplant outdoors After last frost, in sunny spots
June-August Water and fertilise Consistent moisture and feeding

Care and Maintenance

Watering is crucial. Aubergines love consistent moisture, but be careful not to overwater. Ensure the topsoil dries out slightly between waterings.

Feeding your aubergines every couple of weeks with a high-potassium fertiliser helps promote flowering and fruiting. Regularly check for pests and remove any damaged leaves to keep plants healthy.
