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.

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!

Preparation
Sprouting seeds are usually grown indoors in a position away from direct sunlight. Growing the sprouts in the dark will produce sweeter shoots than growing them in a brightly lit position.
You will need the following equipment:
- Either a sprouting jar with a mesh lid OR a glass jar, a piece of muslin or cheesecloth to use as a cover and a rubber band to hold the cover in place.
- A shallow bowl, such as a dessert bowl, for draining.
- Two or three teaspoons of small seeds, or more for larger types.
- Optional: filtered water to rinse and drain the seeds.
How to Grow Sprouting Seeds
- Rinse the seeds in a seive to remove any dust and any noticeably damaged or discoloured seeds.
- Add the desired quantity of seed to the jar and cover with lukewarm water. Approximately 15ml of seed is recommended for a 500ml jar; you will need a larger quantity for larger seeds.
- Attach the lid of the sprouting jar, or cover a normal jar with cheesecloth and secure it with the rubber band.
- Soak the seeds for 12 hours, then tip the jar upside down and drain the excess water. Rinse and drain again.
- Place the jar on its side in a dark, warm place; putting the jar in a shallow bowl with the open end in the bowl can help catch excess water as it drains. Seeds germinate best at temperatures of 10-30°C.
- Rinse and drain the seeds every 8-12 hours until the shoots have emerged and grown to the desired length (usually 3.5-5cm).
- When sprouts are the desired lenght, expose them to sunlight for around 15 minutes or until the shoots turn green. This step is essential to improve the nutritional benefit of the sprouts.
How to Harvest Sprouts
Sprouts should be ready to harvest in approximately 4-14 days.
Sprouts are ready to harvest from the time the sprouted tail is the same size as the original seed. Taste a couple of sprouts from this stage onwards to determine the best time to harvest.
Before harvesting the sprouts, give them a final rinse and drain them thoroughly. Take the sprouts from the jar, discard any unsprouted seeds, and leave sprouts to dry on kitchen paper. Drying the sprouts improves their storage time.
Sprouts are best eaten soon after they are harvested. Sprouts can be stored for three or four days in a sealed container in the refrigerator. Discard immediately if there any signs of mould or any unpleasant smell. Ideally, grow small batches at staggered intervals so you can always eat the sprouts at their freshest.
Common Problems when Growing Sprouts
Like all plants, sprouts is susceptible to some pests, diseases and other problems. Below is a list of the most common problems gardeners encounter when growing sprouts plants:
Seeds not sprouting may be caused by not draining the jar after adding water, overfilling the jar, or seeds having been stored incorrectly or being too old. Use the recommended quantity of seeds for the size of jar; rinse and drain seeds as directed then place the jar on its side so water can drain away; store sprouting seeds in a cool, dry place..jpg)
Smelly or mouldy seeds may be caused by not rinsing the sprouts often enough, temperature being too hot, or mould spores being introduced through using dirty equipment or water. Rinse seeds thoroughly at least twice a day; do not expose jars to temperatures above 30°C; use thoroughly clean jars and lids; and use filtered water to rinse seeds.
Bitter tasting sprouts may be caused by exposing the sprouts to too much light while they were growing or leaving sprouts too long before harvesting them. Sprouts can be grown in the dark and only exposed to sunlight for a short while when they are ready to harvest; harvest sprouts before they develop leaves.
