Northern Rivers NSW Grow Guide
The subtropical gardening guide for the Northern Rivers. Tweed to the Clarence, coastal plains to the hinterland ranges. 109 plants, monthly planting windows, and calendar notes tuned for the NSW end of the subtropical zone.
Where this guide covers
The Northern Rivers runs from the NSW/QLD border at the Tweed down to Grafton and the Clarence Valley, and inland to the ranges around Kyogle and the Tablelands. It is the southern end of Australia's east-coast subtropical zone, and most of the growing advice that works in South East Queensland works here too, with small shifts for cooler winter nights and a slightly shorter summer.
ð Coastal strip
Warm, humid, frost-free. Banana, passionfruit, finger lime, pawpaw, turmeric, lemongrass all thrive. Treat this like coastal SEQ with one extra week of summer at each end.
ð Hinterland valleys
Warm days, cool nights, occasional light winter frost in low pockets. Most subtropical fruit still works. Push winter sowing of tomato and capsicum two weeks later than the coast to dodge the last frost.
ðū Lismore basin & Richmond Valley
Hotter summers than the coast, more frost risk in winter. Brassicas, peas and leafy greens do beautifully April to August. Stone fruit gets more chill than on the coast, so low-chill peaches and plums actually fruit here.
â°ïļ Kyogle & the ranges
Cooler, higher rainfall, regular winter frost above 300m. Apples, figs and temperate berries start to work here. Tropical fruit is marginal above the frost line.
ð Clarence Valley
The southern edge. Milder summers than the Tweed, more winter chill inland. This is where the calendar starts to feel like coastal NSW rather than SEQ. Pecans, citrus and stone fruit all strong here.
How the Northern Rivers calendar differs from SEQ
The Northern Rivers sits about 200 km south of Brisbane and runs a bit cooler in winter, especially inland. For practical purposes the SEQ calendar is your starting point. Four small shifts worth knowing:
- Winter brassicas (broccoli, cabbage, cauliflower) have a slightly longer window. You can push sowing into April and May more reliably than in Brisbane.
- Tomato and capsicum sown in late winter need another two weeks in the hinterland. Wait until late August on the coast, mid September inland.
- Low-chill stone fruit (peaches, plums, nectarines) fruits reliably here. It's marginal in SEQ without the chill hours.
- Tropical edge fruit (jackfruit, abiu, black sapote, soursop) works coastal but struggles in hinterland frost pockets. Stick to frost-tolerant favourites inland.
The plant library
The same 109-plant subtropical library used for SEQ covers the Northern Rivers. Sow months, spacing, companions, varieties, kitchen uses and storage are all the same. Where a plant behaves differently in the Northern Rivers (frost tolerance, chill-hour fruiting) the zone notes above apply.

Monthly planting windows
Use the SEQ monthly calendars as the baseline for Northern Rivers. The timings are accurate for the coastal strip. In the hinterland and Kyogle ranges, push winter-to-spring heat-lovers (tomato, capsicum, eggplant, basil) about two weeks later to clear the last frost risk.
Why the Northern Rivers needs its own notes
Most Australian gardening advice is still written for Melbourne or Sydney. Those calendars tell you to plant tomatoes in spring and brassicas in autumn. Follow them in Ballina and you'll lose your tomatoes to humidity and miss the best brassica window entirely.
The Northern Rivers grows on the subtropical calendar. The best growing season here is April to September, which is the opposite of what the southern state gardening calendars recommend. Winter is dry, mild and productive. Summer is hot, wet and a battle against fungal disease and fruit fly. This guide is calibrated for that reality, not for Melbourne.
Local seed and plant sources
For varieties that actually work in a subtropical climate, source from suppliers who trial in similar zones:
- Green Harvest — Maleny (Sunshine Coast hinterland), subtropical seed specialists. Excellent for bananas, ginger, turmeric and heat-tolerant varieties.
- Eden Seeds — SEQ-based heirloom seeds, strong subtropical range.
- Local markets — Byron, Mullumbimby, Bangalow, Lismore Farmers Markets regularly have seedling stalls with varieties selected by local growers.
- Daley's Fruit Tree Nursery — Kyogle-based, the definitive subtropical fruit tree catalogue for this region.
