When to plant Anise in Subtropical Australia

Subtropical zone — applies to Brisbane, Gold Coast, Sunshine Coast, Coffs Harbour, Lismore and similar areas. Growing elsewhere? Temperate · Cool · Tropical · Arid.

Raise anise seedlings from September to November, transplanting carefully as it dislikes root disturbance, and sow 6 mm deep for germination in 7–14 days. This slow annual needs 120–150 days to ripen its aromatic seed, so an early spring start gets the crop maturing before the worst of the wet-season heat. Space plants about 30 cm apart in rows 30 cm apart, in full sun and free-draining soil. Anise suits subtropical gardens around Brisbane and the Sunshine Coast where a long, warm, relatively dry autumn lets the seed heads ripen and cure properly rather than rotting on the plant.

Growing notes

Anise is grown for its seed, and in the subtropics the whole game is getting those seed heads to ripen and dry before humidity spoils them. The plant itself is undemanding, but the finish is where it can go wrong.

The key failure mode is seed heads rotting or sprouting in the wet. If your crop matures into a run of humid, stormy weather, the ripening umbels hold moisture and go mouldy or germinate in place. Timing the spring sowing so the plant flowers and sets seed heading into the drier autumn is the single biggest lever you have around Coffs Harbour and Lismore.

Anise resents transplant shock, so if you are raising seedlings, use deep cells and move them while young, disturbing the roots as little as possible. Many growers simply direct sow into the final position to sidestep the issue.

Give it steady moisture during vegetative growth, then ease off as the seed heads form to encourage drying. Harvest the umbels as they turn brown, cut whole stems, and finish drying them under cover with good airflow so no moisture is trapped in the seed.

Common questions

When should I plant anise in the subtropics

Sow anise from September to November so the plant flowers and sets seed heading into the drier autumn. This timing helps the seed heads ripen and cure rather than rotting in humid, stormy weather.

How long does anise take to mature

Anise is slow, needing 120–150 days from sowing to ripen its seed. An early spring start is important so the crop finishes before the worst of the wet-season heat and humidity.

Can you transplant anise seedlings

You can, but anise resents root disturbance. Raise it in deep cells and move it while young, or direct sow into its final position to avoid transplant shock altogether.

How do you harvest anise seed

Wait until the seed heads turn brown, then cut whole stems and finish drying them under cover with good airflow. Curing them out of the humidity stops the seed going mouldy.
