Growing guide
Roses for humid Australian climates
Brisbane, the Gold Coast, SEQ hinterland and the northern NSW coast throw everything at a rose — humid nights, wet summers and constant black-spot pressure. The good news: plenty of varieties thrive here if you pick for disease resistance first.
Pick for black-spot resistance
In humid climates the fungus never really goes away. Start with varieties rated "Good" or "Excellent" for black spot and you'll spend far less time spraying.
Airflow beats sprays
Plant with 60–90cm of breathing room, prune to an open vase and keep foliage off the soil. Dry leaves after rain mean fewer fungal cycles.
Water at the roots, not the leaves
Drip or hand-water at ground level in the morning. Overhead watering, especially at dusk, is the fastest way to lose a season to black spot in a subtropical garden.
Our picks for humid gardens

A simple humid-climate routine
- Winter (Jun–Aug): hard prune, clean up fallen leaves, and mulch. Old foliage is where black spot overwinters.
- Spring (Sep–Nov): feed as new growth appears; preventative spray only if you've had disease before.
- Wet summer (Dec–Feb): watch for the first black spots after storms and strip affected leaves early.
- Autumn (Mar–May): ease off nitrogen, keep watering deep and infrequent, and dead-head lightly.
