When to plant Broccoletti in Cool Australia
Cool zone — applies to Hobart, Canberra, Ballarat, Orange, Armidale and similar areas. Growing elsewhere? Temperate · Subtropical · Tropical · Arid.
Raise broccoletti seedlings from January to March for an autumn and winter crop, then again in November and December for a spring picking. Sow seed 5 mm deep into punnets or trays and expect quick germination in just 5–10 days with steady warmth. Transplant the young plants once they have several true leaves, spacing them 30–40 cm apart with 40–50 cm between rows. This fast brassica matures in around 60–90 days, giving you tender, sprouting shoots rather than one large head, so you can harvest repeatedly over several weeks.

Growing notes
Broccoletti thrives in the cool, reliable conditions of Canberra, Orange and Armidale, where crisp autumn nights bring out its sweetness. It is hardy and shrugs off light frost, so the January–March sowings that mature into winter are the most dependable. The spring window suits it too, but push sowing much past December and lengthening days plus early heat will cause it to bolt straight to flower before the shoots fatten.
The unavoidable failure mode here is cabbage white moth. Because `cabbage_moth_target` applies to this crop, drape the bed in fine exclusion netting from the day you transplant. Caterpillars can strip a young plant to stalks within days, and once they are burrowed into the shoots they are almost impossible to remove. Netting is far more reliable than spraying.
Broccoletti is hungry. Dig in plenty of well-rotted compost or aged manure before planting, and side-dress with a nitrogen feed every few weeks to keep the shoots coming. Keep the soil evenly moist, as drought stress also triggers bolting. Harvest the central shoots young, before the buds open, and the plant will push out a succession of smaller side shoots for weeks afterwards.

Common questions
- what is the difference between broccoletti and broccoli
- Broccoletti is a sprouting brassica grown for its slender, tender shoots and leaves rather than one large central head. You harvest it repeatedly as side shoots form, which suits a small cool-climate garden well. It also matures faster than heading broccoli, in around 60–90 days.
- how to stop cabbage moth on broccoletti
- Cover the bed with fine exclusion netting from transplanting day, before the moths ever find the plants. This is the most reliable control because it stops eggs being laid at all. Check regularly for any caterpillars that slip through and squash them by hand.
- when to plant broccoletti in Canberra
- Sow seedlings from January to March in Canberra for the most reliable autumn and winter harvest, when cool nights keep the plants sweet and slow to bolt. A November–December sowing gives a spring crop but risks bolting if it turns warm early. Autumn sowings are the safer bet in a cold zone.
- why did my broccoletti flower too early
- Early flowering, or bolting, is usually triggered by heat or drought stress on a young plant, or by sowing too late into warming spring conditions. Keep the soil consistently moist and mulched, and favour the autumn-into-winter sowing window. Harvest shoots young to slow the plant's rush to flower.
