Basil

Sow seeds · Plant out

Sow into punnets once frost has passed and pinch out flower buds to keep leaves coming. This is a september action in the resolved GrowCal schedule.

Beetroot

Sow seeds

Thin seedlings early — each seed cluster produces several plants. This is a september action in the resolved GrowCal schedule.

Bok Choy

Sow seeds

Grows fast in cool weather; harvest at any size you like. This is a september action in the resolved GrowCal schedule.

Carrot

Sow seeds

Sow direct into deep, friable, stone-free soil and keep the surface damp. This is a september action in the resolved GrowCal schedule.

Chives

Sow seeds · Plant out

Plant in clumps and cut leaves at the base; divide established clumps to make more. This is a september action in the resolved GrowCal schedule.

Coriander

Plant out

Sow direct into cool-season beds and keep it moist; heat and root disturbance make it bolt. This is a september action in the resolved GrowCal schedule.

Dill

Plant out

Sow direct in a sheltered sunny spot; it runs to seed quickly, so keep sowing. This is a september action in the resolved GrowCal schedule.

Eggplant

Sow seeds

Loves heat; pick while the skin is still glossy. This is a september action in the resolved GrowCal schedule.

Ginger

Plant out

Plant rhizome pieces into a warm, shady spot and leave them a full season to bulk up. This is a september action in the resolved GrowCal schedule.

Green Beans

Sow seeds

Sow direct — beans resent transplanting. Pick often to keep them producing. This is a september action in the resolved GrowCal schedule.

Lemon

Plant out · Feed & fertilise

The most forgiving citrus, and the one most worth a big pot. This is a september action in the resolved GrowCal schedule.

Lemongrass

Sow seeds · Plant out

Full sun and moist, well-drained soil; it is frost tender, so pot it in cold districts. This is a september action in the resolved GrowCal schedule.

Lettuce

Sow seeds

Pick outer leaves and keep water up — heat and dryness turn lettuce bitter. This is a september action in the resolved GrowCal schedule.

Lime

Plant out · Feed & fertilise

Tahitian lime is the reliable backyard pick; West Indian lime resents cold. This is a september action in the resolved GrowCal schedule.

Mandarin

Plant out · Feed & fertilise

Thin-skinned and easy to peel — the best citrus for a small yard. This is a september action in the resolved GrowCal schedule.

Mint

Sow seeds · Plant out

Plant into a pot or a contained bed — mint runs, and it prefers moist soil in light shade. This is a september action in the resolved GrowCal schedule.

Orange

Plant out · Feed & fertilise

Feed three times a year and keep the trunk clear of mulch. This is a september action in the resolved GrowCal schedule.

Pumpkin

Sow seeds

Give it room to run, and hand-pollinate early in the morning for reliable fruit. This is a september action in the resolved GrowCal schedule.

Sow seeds · Feed & fertilise

Frost sensitive and hungry for sun — give it six hours a day and room to spread. This is a september action in the resolved GrowCal schedule.

Rosemary

Sow seeds · Plant out

Give it hot, dry, well-drained conditions; in the tropics and subtropics keep it in a pot. This is a september action in the resolved GrowCal schedule.

Sage

Sow seeds · Plant out · Prune

A permanent full-sun spot with very sharp drainage; do not enrich the soil. This is a september action in the resolved GrowCal schedule.

Shallot

Sow seeds

Push the bulbs in with their tops just showing and leave them room. This is a september action in the resolved GrowCal schedule.

Silverbeet

Sow seeds

Pick the outer leaves and one planting will feed you for most of the year. This is a september action in the resolved GrowCal schedule.

Sweet Corn

Sow seeds

Plant in a block, not a row, so the flowers pollinate each other. This is a september action in the resolved GrowCal schedule.

Thyme

Sow seeds · Plant out

Full sun and gritty, free-draining soil; shear off spent flowerheads to keep new growth coming. This is a september action in the resolved GrowCal schedule.

Watermelon

Sow seeds · Plant out · Feed & fertilise

Sow into warm soil with room to run, and ease off water once the fruit sizes up. This is a september action in the resolved GrowCal schedule.

Why timing varies locally

Brisbane is not one uniform growing environment. This page uses the mapped Brisbane, Gold Coast & SEQ Coastal profile, while a nearby locality may resolve differently. Frost pockets, shade, soil, aspect and the variety you grow can all change what is sensible in a particular garden. Treat these dates as a prompt to look at your garden, not a rigid instruction.
