When to plant Caraway in Arid Australia

Arid zone — applies to Alice Springs, Mildura, Broken Hill, Kalgoorlie, Port Augusta and similar areas. Growing elsewhere? Temperate · Cool · Subtropical · Tropical.

Sow caraway direct from June to August, placing seed about 10 mm deep straight into its final position because the taproot resents transplanting. Germination takes 10–20 days in cool soil, and as a hardy biennial it needs the full 365 days to run to seed, so patience is part of the deal. Thin seedlings to 25 cm apart in rows 25–30 cm apart. Winter sowing in Kalgoorlie or Port Augusta uses the cooler, gentler months to establish a strong rosette before the plant bolts and sets its aromatic seed the following season.

Growing notes

Caraway is grown for its seed, and in an arid climate the challenge is carrying the plant through a scorching first summer so it can flower and seed in year two. It forms a low leafy rosette in its first season, then sends up flowering stems the next spring.

The common failure here is losing seedlings to heat and drought before they establish, or having the plant bolt prematurely under stress. Sow into cool winter soil so roots go down before summer, mulch to hold moisture, and water deeply but infrequently to encourage the taproot to chase moisture downward. Light afternoon shade through the first summer in Broken Hill or Alice Springs helps a young rosette survive.

Because it is direct-sown and slow, keep the bed weed-free early so seedlings aren't outcompeted. Once flowering, let the umbels dry on the plant and harvest seed heads as they turn brown, before they shatter. Cut whole heads into a paper bag and finish drying under cover. Avoid rich, wet ground; caraway prefers a free-draining, moderately fertile soil and dislikes waterlogging more than it dislikes dry spells.

Common questions

can you grow caraway in a hot dry climate

Yes, but it is a biennial that needs to survive its first summer to seed in the second year. Sow in winter so plants establish in cool soil, then mulch and water deeply to carry them through arid heat.

why won't my caraway produce seed

Caraway is biennial and usually only flowers and seeds in its second year after a cool period. If it hasn't seeded, it may simply be too young, or heat stress may have set it back; give it steady care through to the following spring.

how deep do you plant caraway seed

Sow caraway seed about 10 mm deep directly where it is to grow. It has a taproot and dislikes being moved, so avoid transplanting seedlings.

when do you harvest caraway seeds

Harvest once the flower umbels turn brown and the seeds begin to dry, before they shatter and fall. Cut the heads into a paper bag and finish drying them under cover.
