A bee magnet as well as a herb: sun, poor soil and neglect suit it best.

Care

Light

Full sun for the strongest flavour.

Water

Low — drought-tolerant; rots in wet winter soil.

Soil

Poor to moderately fertile, very well-drained soil; happy on chalk.

Pruning

Pick regularly. Cut back after flowering to encourage fresh leaves, and trim old growth to the base in spring.

Feeding

No feeding in the ground — lean soil gives the best flavour. A light feed occasionally in pots.

Propagation

Divide in spring, or take softwood cuttings in early summer. Seed of the species comes true; named forms don't.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.
