When to plant Curry Plant 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 curry plant from seed under cover from August to November, then transplant the seedlings out once they are sturdy. Sow shallowly at about 3 mm deep, as the fine seed needs light to germinate, and expect it to be slow and uneven over 14–21 days. Plants reach usable size in around 90–120 days and space to 30–60 cm, with rows about 60 cm apart. This silvery Mediterranean shrub prizes dry heat and sharp drainage, so gardeners in drier subtropical inland areas will have more luck than those in the humid coastal strip from Brisbane to Coffs Harbour.

Growing notes
Curry plant (the aromatic Helichrysum, not curry-leaf tree) is a tough, drought-hardy perennial once established, but its needs run against the grain of a subtropical climate. It wants lean, gritty, free-draining soil and full sun, and it will quickly rot in rich, moisture-holding beds during the wet.
Start seed in trays under cover, barely pressing it into the surface, and be patient, since germination is slow and patchy. Prick out the strongest seedlings and grow them on before planting into their permanent spot with plenty of room for air to move around the silver foliage.
The main failure mode in this zone is root and crown rot through the humid summer. Plant on a mound or in a raised bed, mix coarse sand or grit into the soil, and never mulch heavily against the stem. Water sparingly, letting the soil dry between drinks, and cut plants back after flowering to keep them open and airy. In the coastal humidity around the Gold Coast, a pot of gritty mix on a sunny, sheltered wall is often more reliable than an open garden bed.

Common questions
- how do you grow curry plant from seed
- Sow seed under cover from August to November at about 3 mm deep, as it needs light to germinate, then transplant sturdy seedlings out. Germination is slow and uneven, often taking 14–21 days.
- does curry plant grow in humid climates
- It struggles, as curry plant prefers dry Mediterranean conditions and rots in humid, wet soil. Grow it on a raised, gritty, free-draining mound in full sun, or in a pot you can keep sheltered.
- how far apart to plant curry plant
- Space plants 30–60 cm apart with rows about 60 cm apart. Generous spacing keeps air moving around the foliage and helps prevent rot in subtropical humidity.
- why is my curry plant rotting
- Curry plant rots at the crown and roots in wet, humid conditions. Improve drainage with grit, plant on a mound, water sparingly, and avoid heavy mulch against the stem.
