When to plant or sow Aubergine?

Aubergines are heat-loving tender vegetables that demand full sun and warm, sheltered conditions to crop successfully in temperate Europe. They are not frost-hardy (zones 9–11) and must be planted outdoors only after all risk of frost has passed, typically in May or June when soil temperatures have warmed reliably above 15°C. Choose the sunniest, most protected spot in your garden—against a south-facing wall is ideal—or grow them in a greenhouse or polytunnel for more reliable results. Prepare the soil by digging in plenty of well-rotted compost or manure several weeks before planting; aubergines thrive in fertile, moisture-retentive loam with good drainage. Raised beds warm up faster and are worth considering if your soil is heavy. If growing in containers, use large pots (at least 30 cm diameter) filled with a high-quality peat-free compost mixed with extra organic matter. Plant young aubergine plants (started indoors from seed in March or April, or bought as plugs) at a spacing of 60 cm to allow good air circulation and room for the mature spread of 50–70 cm. Set them at the same depth they were growing in their pots. Water thoroughly after planting to settle the roots, then apply a 5 cm layer of organic mulch around the base to conserve moisture and suppress weeds—keeping the mulch clear of the stem itself. Stake each plant with a sturdy cane at planting time, as the stems can become top-heavy once fruits develop. Tie in loosely as the plant grows.
