Best months by climate
Highlighted months are the usual planting window. A local nursery, seed packet and current weather forecast should take priority over a broad climate calendar.

Start well
Plant eggplant with confidence
Start in trays. Sow about 5 mm in trays, using clean seed-raising mix for trays and keeping the surface evenly moist until established.
- Sowing or planting depth
- about 5 mm in trays
- Germination or establishment
- Usually 10–21 days with consistently warm seed-raising conditions.
- Spacing
- 50–70 cm
- Soil
- Fertile, free-draining soil enriched with compost; usually ph 6.0–6.8.
Feeding
Support steady growth
Apply compost before planting, then use a balanced feed as flowering begins.
Water
Keep moisture balanced
Water deeply and consistently through flowering and fruit development.
Maintenance
What to do as it grows
Support tall or fruit-heavy growth and maintain even watering as flowers and fruit develop.
Harvest or display
Know when it is ready
16–22 weeks. Readiness varies with variety and weather; use colour, firmness, size and the supplier's maturity notes rather than the calendar alone.
Problems and companions
Keep your patch healthy
Common watch-outs
Watch for aphids, mites, caterpillars and fungal leaf spots. Avoid wetting foliage late in the day and rotate away from other nightshade crops.
Useful neighbours
Basil, parsley, marigold and alyssum can share the bed where spacing allows. Avoid following tomato, potato, capsicum or eggplant in the same soil.
People and pets
Safety note
No Patch-specific toxicity warning is recorded. That does not prove the plant is safe—check the exact species with a veterinarian or poisons service if children or pets may eat it.
Moving plants
Biosecurity note
Fruit, plants and soil can be restricted between Australian states and pest-control zones. Check current interstate quarantine rules before moving them.
Transparent guidance
How to use this guide
Patch gives a broad Australian starting point, not a guarantee for every variety or garden. Read the Patch methodology and sources, check the latest Bureau of Meteorology climate information, and confirm interstate restrictions through Australian Interstate Quarantine.
