When to plant Candytuft in Subtropical Australia
Subtropical zone — applies to Brisbane, Gold Coast, Sunshine Coast, Coffs Harbour, Lismore and similar areas. Growing elsewhere? Temperate · Cool · Tropical · Arid.
Sow candytuft direct from March to July, setting the seed about 5 mm deep in a sunny, well-drained bed once the summer humidity has eased. Germination takes 14–21 days, and the dense flat-topped clusters of white, pink and mauve flowers appear in 80–100 days. Thin plants to 25 cm apart, with rows 25 cm apart, so they form a tidy, low mound. This hardy annual suits the mild, dry subtropical cool season, so an autumn sowing around Brisbane or Lismore gives weeks of pollinator-friendly bloom through winter and into spring.

Growing notes
Candytuft is a low, quick-flowering annual that edges beds and paths beautifully and draws bees while it blooms. It performs best sown into the drier months from March to July, when cool, settled weather keeps growth compact and flowering heavy.
The common failure in the subtropics is stem and crown rot in warm, wet conditions, along with sparse flowering if plants are given too much shade or rich feeding. The fix is free-draining soil, full sun, honest spacing at 25 cm for airflow, and watering at the base rather than over the foliage. Avoid sowing into the humid summer, when seedlings damp off readily.
Candytuft is not fussy about soil fertility and flowers well in leaner ground, so go easy on nitrogen, which pushes soft leaf at the expense of bloom. Shearing plants lightly after the first flush encourages a second round of flowers and keeps the mound neat. Around the Gold Coast and Coffs Harbour, treat candytuft as a cool-season display and clear it before the wet returns and rot sets in.

Common questions
- when to plant candytuft in the subtropics
- Sow direct from March to July, after the summer humidity fades. Candytuft flowers best through the mild, dry subtropical cool season, so an autumn start gives the strongest display.
- why is my candytuft rotting
- Candytuft rots at the stem and crown in warm, wet, crowded conditions. Grow it in full sun with free-draining soil, space plants 25 cm apart for airflow, and water at the base rather than over the leaves.
- how do I get candytuft to reflower
- Shear the plants lightly after the first flush of flowers fades. This tidies the mound and encourages a second round of bloom before the plants finish for the season.
- does candytuft need full sun
- Yes, candytuft flowers best in full sun. In shade the plants grow leggy and bloom sparsely, and the extra moisture around the crown increases the risk of rot in humid weather.
