When to plant Candytuft in Temperate Australia
Temperate zone — applies to Sydney, Melbourne, Adelaide, Perth, Newcastle and similar areas. Growing elsewhere? Cool · Subtropical · Tropical · Arid.
Sow candytuft direct from February to June, planting seed 5 mm deep in a sunny, well-drained bed. Germination takes 14–21 days, and the flat clusters of white, pink and lilac flowers appear in 80–100 days. Sow where it is to flower, as it dislikes transplanting, and thin plants to 25 cm apart in rows 25 cm apart. This hardy annual copes easily with temperate frosts, so autumn and early-winter sowings around Melbourne, Adelaide and Perth flower from late winter into spring, edging paths and borders with low, dense mounds that pull in bees.

Growing notes
Candytuft is a reliable, low, spreading annual that suits the cool-season temperate calendar. The February-to-June window lets seedlings establish through autumn and flower from late winter, and because it is hardy it takes frost in its stride. Sow direct — it flowers poorly if the roots are disturbed — and keep the surface moist during the two to three weeks it takes to germinate.
The main failure mode is poor flowering from too much shade or overly rich soil, which produces soft, floppy growth and few blooms. Give it full sun and a lean, free-draining bed; candytuft actually flowers better on ordinary or slightly poor soil than on heavily fed ground. In damp winter beds around Melbourne, watch for stem rot where drainage is poor, and improve the soil with grit if water sits after rain.
A light shear once the first flush of flowers fades keeps the mounds compact and often triggers a second showing. It works beautifully as a path edge or rockery filler and, being nectar-rich, draws bees and hoverflies that benefit the wider garden. Deadheading extends the display, though you may want to leave a few heads to self-seed for next season. Pest pressure is low, with only the occasional aphid on soft new growth.

Common questions
- When should I sow candytuft in temperate gardens?
- Sow direct from February to June for flowers from late winter into spring. Candytuft is hardy and handles temperate frosts, so autumn sowings around Melbourne and Adelaide establish well before blooming. Sow where it is to flower, as it dislikes transplanting.
- Why is my candytuft growing leggy with few flowers?
- Leggy, sparse candytuft is usually the result of too much shade or overly rich soil. Grow it in full sun on lean, free-draining ground, where it flowers far more freely. A light shear after the first flush keeps the mounds compact.
- How long does candytuft take to flower from seed?
- Allow 80–100 days from sowing to flowering, with seed germinating in 14–21 days. Autumn sowings sit through the cooler months and then flower from late winter. Deadheading extends the display over several weeks.
- Does candytuft attract bees?
- Yes, the nectar-rich flower clusters draw bees and hoverflies, making it a useful filler among vegetables and along borders. The hoverflies it attracts also help control aphids in the wider garden. Leave a few heads to self-seed for next season.
