Climate Zones for Australian Gardeners
Knowing your climate zone will help you decide the best time to sow the vegetables, herbs and flowers you want to grow, and which varieties should perform well in your garden. Growing plants that are suited to your climate zone will usually give you the best results in your garden.
How to Use Climate Zones
First, find your climate zone using the map or descriptions below. Next, refer to our sowing chart, which provides approximate sowing times for our most popular seeds for each climate zone.
While knowing your climate zone is helpful when planning your garden, there are many other factors that may affect how your plants grow, including unseasonal weather conditions, the specific microclimate of your garden and how you care for your plants. You know your garden better than us, so if a different climate zone seems to ‘fit’ your garden better, go ahead and use it as a guide.
Our climate zones cover huge areas of Australia, so we recommend gardeners also consider their local conditions when planning what and when to plant. For example, gardeners in alpine areas have shorter growing seasons than gardeners in cool coastal areas, even though both alpine and coastal areas are included in our ‘Cool Temperate’ climate zone. We recommend gardeners in cool regions look at the ‘days to maturity’ information provided for each variety and choose those that will mature in a short (6-12 week) growing season.
Tropical
- Includes: Darwin, Cairns, Townsville, Exmouth
- High humidity summers with most rainfall in summer and dry, warm winters. Includes northern Australia from Exmouth (WA) across to south of Townsville (Qld).
- Set as my climate My climate
Arid

- Warm humid summers with high summer rainfall and mild winters. Includes coastal Queensland and northern NSW from north of Mackay to just south of Coffs Harbour.
- Set as my climate My climate
Temperate
- Includes: Sydney, Perth, Adelaide, Newcastle, Toowoomba, Central Coast NSW, Wollongong, Bunbury
- Moderate humidity and reliable rainfall, with four distinct seasons. Includes coastal areas from north of Port Macquarie to south of Woollongong in NSW, coastal SA and the southeastern coast of WA.
- Set as my climate My climate
Cool Temperate
- Includes: Melbourne, Canberra, Hobart, Launceston, Ballarat, Bendigo, Geelong, Mt Gambier
- Low humidity with most rainfall in winter; hot dry summers and cold winters. Some regions will experience frosts and snow. Includes coastal areas of south-eastern Australia and alpine areas of Victoria, NSW and Tasmania.

Climate Zones FAQ
What if I can’t find my climate zone?
If you can’t locate your zone from looking at the map or the descriptions on this page, we suggest that you think of
an area that has a climate that’s similar to yours and use the zone for that area as a guide.
What if I live on the border of two zones?
If you live near the border between two zones we suggest you read the descriptions for both zones and decide which
best describes the climate where you live. Depending on the microclimate in your garden, you may be able to grow a
wider range of plants over a longer season than others in your zone. Lucky you!
What is a microclimate?
A microclimate is a small area where the temperature or humidity differs to the climate of the surrounding area. For
example, if you live in a climate zone where frosts are common but your garden is protected by buildings or large
trees, your garden may be frost-free. Similarly, if you live in a warm temperate zone but your garden is at a high
altitude your microclimate may have more in common with the cool temperate zone, so use this as a guide when
deciding which zone is relevant to you.
Can I grow varieties not listed for my climate zone?
While our climate zones and sowing chart will help you decide what is suitable to plant in your garden, they provide
general guidance only. We recommend you start by sowing seed that’s recommended for your climate zone; once you get
a few successes under your belt you can experiment with varieties in neighbouring zones and see how you go –
gardening is all about experimenting after all!
How to Save Okra (Abelmaschus esculentum) Seeds
Seed Saving Guide #2721
Family: Malvaceae
Binomial name: Abelmaschus esculentum
Flower Type | Perfect, self-fertile |
---|---|
Pollination | Self-pollinated and insect pollinated |
Isolation Distance | 250m |
Other Isolation Methods | Cover flowers with paper bags. |
Population Required for Viable Seeds | 1 |
Population Required to Maintain Variety | 5-10 |
When to Harvest | When capsules dry and harden and before they split open. |
How to Harvest | Cut individual capsules from the plant and dried until they become brittle. Split capsules and remove the seed. |
How to Clean | Separate seeds by hand or by screening and winnowing. |
Image of Seeds |
'Okra (Abelmaschus esculentum)' has Perfect, self-fertile flowers.
Perfect: Flowers have both male and female parts.
Self-fertile: Flowers can pollinate themselves.
'Okra (Abelmaschus esculentum)' seed is best cleaned using the following methods:
Screen: Use a sieve, colander, mesh or riddle to separate the seeds from the chaff.
Winnow: Pour the seeds from a height and let wind or air from a fan blow the chaff away, leaving the seeds to fall into a container.
Okra (Abelmaschus esculentum) requires a population size of at least 1 plant(s) to produce viable seed.
When saving Okra (Abelmaschus esculentum) seeds it's recommended to grow at least 5-10 plants to maintain the traits of a variety and avoid losing vigour within the variety due to limited genetic diversity (inbreeding depression).
'Okra (Abelmaschus esculentum)' requires an isolation distance of at least 250m.
Isolation Distance: The minimum distance needed between cross-pollinating species to prevent cross-pollination. The plant that will produce the seeds to be saved should be at least this distance away from plants of cross-pollinating species in every direction.
'Okra (Abelmaschus esculentum)' can be isolated using these alternate methods: Cover flowers with paper bags.
Paper bags: Isolate individual flowers by covering them with paper or mesh bags and tying them securely at the top to prevent insects and pollen from other plants pollinating flowers.
What is Seed Saving?
Seed saving is the practice of collecting and storing mature seeds from open-pollinated plants. By allowing plants to reach full maturity and harvesting the seeds, they can be cleaned, dried, and stored for future use.
