  1. Sow the seeds indoors from January-April, at a depth of around 10 mm.
  2. Place 4 seeds per 8cm pot.
  3. Keep at a temperature of 10-15c.
  4. Germination should occur between 14-21 days.
  5. Once the first set of true leaves has developed, thin the seedlings to the strongest plant per pot.
  6. Gradually acclimatise the seedlings before planting outside when they are around 15cm tall.
  7. Make a hole around 15cm deep using a dibber and place the seedling inside.
  8. Fill the hole with water rather than soil, allowing the soil to settle naturally around the roots.
  9. Alternatively, sow directly outdoors between March-April.
  10. As the seedlings grow, thin them to around 20cm apart.
  11. Regularly weed and water the area as needed.
  12. Earth up around the stems as they grow to help produce longer white shanks.
  13. Harvest alternate plants from autumn through winter.
  14. This variety can stand until May in the ground.
