When to plant Caraway in Cool Australia

Cool zone — applies to Hobart, Canberra, Ballarat, Orange, Armidale and similar areas. Growing elsewhere? Temperate · Subtropical · Tropical · Arid.

Sow caraway direct from February to April or again from September to November, dropping seed 10 mm deep into a sunny, well-drained bed. It germinates in 10–20 days and, as a biennial, takes the full 365 days to flower and set the aromatic seed you are after in its second year. Thin seedlings to 25 cm, with 25–30 cm between rows. Caraway resents transplanting, so always sow it where it is to grow. In cool districts around Orange and Armidale the cold winters actually help, giving the plant the chill it needs to trigger flowering the following summer.

Growing notes

Caraway is hardy and well suited to cool climates, where the reliable winter cold does the vernalising work needed for a strong second-year flush of seed. Sow direct in autumn for establishment before winter, or in spring once the soil is workable. It dislikes root disturbance, so resist the urge to raise it in trays.

The classic disappointment with caraway is a first year that looks like nothing happened. In year one the plant makes only a low rosette of ferny leaves, then flowers and seeds in year two before dying. Gardeners who pull it out that first autumn, thinking it failed, never see a harvest. Mark the row and be patient.

Good drainage matters more than rich soil. In heavy, wet winter ground the taproot rots, so raise the bed or work in grit if your soil holds water around Ballarat or Hobart. Keep the bed weed-free while seedlings are small, as caraway is slow to cover ground. When the second-year seed heads turn brown, cut whole stems, hang them over a sheet or paper bag, and let the seed dry and drop.

Common questions

How long does caraway take to produce seed?

Caraway is a biennial, so it takes roughly 365 days. It forms a leafy rosette in the first year, then flowers and sets seed in its second summer before dying. Patience through that first quiet year is the main thing.

Can you transplant caraway seedlings?

It is best not to. Caraway forms a taproot and resents root disturbance, often bolting or sulking after transplanting. Sow the seed direct at 10 mm deep where the plants are to grow and thin to 25 cm apart.

Does caraway need winter cold to flower?

Yes, and cool districts like Orange and Armidale suit it well. The winter chill vernalises the plant so it flowers reliably the following summer. This is one crop where a genuinely cold winter is an advantage.

Why won't my caraway flower?

In its first year caraway simply will not flower, no matter what you do. It needs a full season plus winter cold before it bolts to seed in year two. If it is still a leafy rosette in autumn, that is normal, so leave it in place.
