# Australian climate zones used by Yard Yield

The website uses five broad garden climate regions: tropical, subtropical, arid/dry, warm temperate and cool temperate/highland. Its postcode suggestions are approximate and adjustable. They are not a verified national suburb-level climate map or the eight-zone NCC building classification.

The website's reviewed calendar covers 27 crops, with separate sowing and seedling windows. Where the two sources give different sowing windows, it uses their shared months; when only one source supplies a window, that explicit window is used. Missing evidence is never filled from another climate zone. Seven inherited crop calendars are withheld.

Sources: [Gardening Australia magazine](https://www.gardeningaustraliamag.com.au/planting-guide/) and [The Seed Collection sowing chart](https://www.theseedcollection.com.au/assets/files/Sowing_Chart%20-%20The%20Seed%20Collection%20Pty%20Ltd.pdf). Checked 21 October 2026; the secondary chart was updated June 2022.

These are general regional windows, not professional horticultural approval. Frost, soil temperature, cultivar, altitude and local conditions affect planting times. The native app catalogue and website's smaller reviewed calendar are distinct datasets.
