September in spring is one of twelve windows the Australian year offers, and whether you can plant lettuce this month depends on which corner of the country you're standing in. Below is the per-city read: where lettuce is being sown from seed, where it's going in as seedlings, and where it's already being harvested.
No major Australian city is sowing lettuce from seed in September. Transplanting lettuce seedlings in September: Sydney, Melbourne, Brisbane, Perth, Adelaide. Harvesting lettuce in September: Sydney, Brisbane, Perth.
Across Australia's climate zones, lettuce keeps to tropical, april-august (cool season only); subtropical, march-september; temperate, february-may, august-november; cool, september-april (spring through autumn); arid, march-september. September sits inside that window for the subtropical, cool, arid zones. The longer version, including the climate-zone-by-zone breakdown, lives on the Lettuce growing guide.
Lettuce is one of the easiest and most rewarding crops for Australian raised bed gardeners. It prefers cool weather and will bolt (run to seed) quickly in temperatures above 25掳C, so timing is everything. In most Australian climates, autumn through spring is the prime lettuce season.
If you're planting lettuce this September, the bed prep is the same as any other month: a 30 cm-deep raised bed worked through with compost, spacing of 25 cm between plants, and partial shade to full sun, afternoon shade in summer. The crop takes 45-70 days, which means a September planting will be ready around November. Use the raised bed calculator to size the bed and the companion planting guide to fill it out.
For a household of four, Plant 8-12 plants in succession for a family of 4; succession sow every 3 weeks for continuous supply Expected yield is 200-500g per plant (heading); ongoing for cut-and-come-again.
The September lettuce read changes city by city. The list above is the high-level signal; for the exact dates and bed-by-bed planting plan, the Plant Planner lettuce module reads your postcode and your bed dimensions and does the rest of the maths.
Whether September works for lettuce depends on your climate zone. The planting windows are: tropical, april-august (cool season only); subtropical, march-september; temperate, february-may, august-november; cool, september-april (spring through autumn); arid, march-september. In September specifically, the broad rules suggest it's a planting month in the subtropical, cool, arid zones.
Lettuce takes 45-70 days. A September planting will be ready around November. For loose-leaf varieties, harvest outer leaves continuously, leaving the growing centre intact. For heading types, harvest the whole head when firm. Harvest in the morning for maximum crispness. Bolting plants (elongated central stem) taste bitter, harvest immediately or compost them.
Plant 8-12 plants in succession for a family of 4; succession sow every 3 weeks for continuous supply Yield expectation: 200-500g per plant (heading); ongoing for cut-and-come-again.
Partial shade to full sun, afternoon shade in summer. Regular, keep consistently moist but not waterlogged. Soil pH 6.0-7.0. Spacing 25 cm between plants, 30 cm between rows.
