What can I plant right now?
Your postcode gives you your Australian climate zone, and your zone gives you this month's sowing windows for hundreds of vegetables, herbs, fruit and flowers. Free, and no account needed.
- Five Australian climate zones, area-weighted per postcode
- Month-by-month sowing windows for every crop
- Border postcodes show both zones, honestly
We never store or share your postcode — only the zone it resolves to.
