Getting started

Sowing and space

Sow into warm mix or plant healthy seedlings; pinch the growing tips once established.

The cycle is an editorial band linked to the method above. Cultivar, temperature, transplant age and the harvest stage can change it.

Allow about 20 cm of usable depth and roughly 22 cm between plants. A suitably sized container can work when the full root volume and mature canopy are allowed.

Water demand is moderate and regular. That is not a fixed timetable: heat, wind, rain, container size and growth stage change the interval.

Planting windows by broad profile

The highlighted months are conservative editorial references, not a current forecast or postcode calendar. Confirm the cultivar, packet, current warning and local advice.

Practical care

  • Harvest above a leaf pair to encourage branching.
  • Use a free-draining pot with room for repeated watering.

Points to check

  • Cold snaps can stop growth.
  • Constantly wet foliage and crowded stems increase disease risk.

Provenance and confidence

This rule is editorial guidance without claimed independent agronomic review. Confidence describes evidence coverage, not the chance of a harvest.
