Getting started

Sowing and space

Plant disease-free cloves sold for planting and suited to the local region.

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

Allow about 30 cm of usable depth and roughly 12 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.

Use a cultivar and timing matched to local winter conditions.

Practical care

  • Keep the bed weed-free through the long cycle.
  • Reduce irrigation as mature foliage naturally dries, following local guidance.

Points to check

  • Do not plant supermarket cloves or imported material of uncertain planting status.
  • Wet soil can rot cloves.
