What to Plant in Each Season: An Australian Gardening Calendar

A productive garden begins with timing. Seeds and seedlings respond to soil temperature, daylight, rainfall and frost, so the best planting month in Hobart may be quite different from the best month in Brisbane. A reliable gardening calendar helps you plan crops around Australia’s reversed seasons instead of relying on northern hemisphere advice.

This month-by-month guide covers vegetables, herbs, flowers and useful garden tasks for balconies, courtyards and larger backyards. Treat the dates as a flexible framework: local microclimates, summer heatwaves, coastal winds and regional water restrictions can all shift the ideal planting window by several weeks.

Month Main Season Good Plants To Sow Or Plant Useful Garden Tasks
January Summer Beans, cucumber, basil, sweet corn, capsicum Water deeply, mulch, shade tender seedlings
February Summer Carrots, beetroot, lettuce, zucchini, coriander Replace tired summer crops and check pests
March Autumn Peas, spinach, broccoli, cabbage, parsley Add compost and prepare beds for cool weather
April Autumn Broad beans, onions, garlic, potatoes, silverbeet Plant bare-root fruit trees in cooler districts
May Autumn Leeks, radish, kale, strawberries, pansies Protect seedlings from slugs and heavy rain
June Winter Peas, snow peas, brassicas, coriander, violets Prune deciduous fruit trees and improve drainage
July Winter Potatoes, onions, carrots, lettuce, calendula Start spring seeds in trays and inspect frost damage
August Winter Asparagus crowns, peas, spinach, seedlings of herbs Weed before spring growth accelerates
September Spring Tomatoes, basil, beans, cucumbers, marigolds Harden off seedlings and install supports
October Spring Pumpkin, sweet corn, eggplant, capsicum, nasturtium Mulch beds and watch for snails and aphids
November Spring Melons, zucchini, beans, summer herbs, sunflowers Increase watering as temperatures rise
December Summer Cherry tomatoes, basil, beans, cucumbers, okra Harvest frequently and protect plants from heat

Planting Calendar At A Glance

In January and February, focus on warm-season crops that can handle strong sunlight. Bush beans, cucumbers, basil, zucchini and sweet corn grow quickly when the soil is warm. In cooler southern areas, provide afternoon shade for lettuce and coriander, while gardeners in Perth or inland New South Wales may need shade cloth, thick mulch and early-morning watering to prevent plants from wilting.

Autumn is one of the most rewarding growing periods across much of Australia. From March to May, falling temperatures make it easier to grow peas, spinach, broccoli, cabbage, carrots and beetroot. Garlic and onion bulbs are commonly planted in April or May, while strawberry runners can settle in before winter. Choose disease-free planting material and rotate brassicas through different beds each year.

Winter planting varies sharply by location. In Melbourne, Canberra and Tasmania, frost can slow growth, so sowing under cover or using seed trays is helpful. In frost-free parts of Brisbane, northern New South Wales and coastal Western Australia, winter is often ideal for leafy greens, herbs and root vegetables. July and August are also good months to prepare for spring tomatoes, beans and cucumbers.

Summer Sowing From December To February

Summer crops need consistent moisture rather than short, frequent splashes of water. Water the soil deeply in the early morning, then allow the surface to dry slightly between sessions where appropriate. A 5–8 centimetre layer of sugar cane mulch, pea straw or composted organic material reduces evaporation and keeps shallow roots cooler.

Plant seeds in small batches every two or three weeks instead of sowing an entire packet at once. This succession planting spreads the harvest and prevents a glut of beans, zucchini or lettuce. In hot districts, choose heat-tolerant varieties and use shade cloth during afternoon extremes. Check leaves regularly for whitefly, caterpillars, aphids and powdery mildew, particularly after humid weather.

Summer is also a useful time to grow herbs in pots. Basil, mint, lemongrass, thyme and rosemary can thrive near a kitchen door, although mint is best contained because it spreads aggressively. Containers dry out faster than garden beds, so use a quality potting mix, ensure drainage holes are clear and group pots together to create a slightly more humid growing environment.

Autumn Crops For Reliable Harvests

As days shorten, replace exhausted summer plants with vegetables that prefer cool conditions. Broccoli, cabbage, cauliflower, kale and silverbeet can be planted as seedlings, while peas and broad beans are usually most successful when sown directly into prepared soil. Carrots, radishes and beetroot also benefit from loose soil without large stones or fresh manure.

Before planting, remove diseased leaves and old roots, then add mature compost to the top layer of the bed. Avoid planting the same vegetable family in the same position year after year. Rotating tomatoes, potatoes, capsicums and eggplants away from the previous season’s bed helps reduce the build-up of soil-borne pests and diseases.

Autumn is an excellent period for garden planning because the weather is generally easier to work in. Sketch the position of paths, raised beds, trellises and compost bins, taking note of winter shadows. For additional garden planning ideas, compare the space available with the mature height and spread of each plant rather than filling every gap immediately.

Winter Planting In Southern And Northern Gardens

Winter is not a dormant season everywhere in Australia. In warmer areas, gardeners can continue planting lettuce, Asian greens, coriander, peas, potatoes, carrots and spring onions. Queensland’s subtropical climate may support coriander and leafy greens through winter, while some tropical areas are better suited to crops that tolerate humidity and heavy rain.

In frosty regions, wait until the coldest part of winter has passed before planting tender herbs and summer vegetables. Protect young plants with cloches, fleece or a simple clear cover that is removed during sunny days. Raised beds can improve drainage and help soil warm faster, but they may also dry out quickly once spring arrives.

Midwinter is a useful time to prune deciduous fruit trees while they are dormant, provided the variety and local conditions make pruning appropriate. Remove dead, crossing or damaged branches with clean tools, and check local advice for pest and disease management. In some Australian councils, significant trees or trees on protected lists require permission before removal or major pruning, so check municipal rules before cutting.

Spring Planting For Fast Growth

Spring brings longer days, warmer soil and rapid growth. Tomatoes, basil, cucumbers, beans, pumpkins, corn and eggplants can be planted once the danger of frost has passed. In Melbourne or Canberra, that may mean waiting until October or even early November, while warm coastal districts can often begin earlier.

Harden off seedlings before moving them outdoors permanently. Set trays outside for a few hours in a sheltered position, gradually increasing their exposure to sun and wind over about a week. This reduces transplant shock and helps soft nursery growth adapt to real garden conditions.

Spring is also the right time to install trellises before climbing plants become tangled. Beans, cucumbers, peas and passionfruit need strong support, while pumpkins and melons require plenty of ground space. Planting marigolds, alyssum and nasturtiums around edible crops can add colour and attract beneficial insects, though companion planting should complement sound watering, spacing and pest control rather than replace them.

Match Plants To Your Local Conditions

Australia’s climate zones make a single national planting date impossible. Sydney and coastal New South Wales often have mild winters and humid summers; Adelaide has dry conditions and hot spells; Perth has wet winters and dry summers; Melbourne experiences changeable weather; and Brisbane can support a wide range of subtropical crops. Use local nursery advice and regional planting guides to adjust the calendar.

Sun exposure is equally important. Most vegetables need six or more hours of direct sunlight, but leafy greens, parsley and coriander can appreciate morning sun with afternoon shade in very hot suburbs. Observe your yard throughout the year, since a sunny winter bed may become shaded by a neighbour’s tree or your own deciduous plants in summer.

Water availability should shape crop selection. State and local restrictions can affect when and how gardens may be watered, especially during drought or prolonged heat. Choose drought-tolerant herbs, install drip irrigation where permitted, collect rainwater in accordance with local rules and mulch bare soil. Native flowering plants can also support pollinators while using less water once established.

Practical Habits For A Productive Garden

Small maintenance habits have a noticeable effect on plant health and harvest quality. Keep records of sowing dates, successful varieties, pest outbreaks and first harvests. A simple notebook or phone note will gradually reveal what performs best in your suburb, including which beds stay wet, which receive harsh afternoon sun and which crops bolt early.

Garden layout also affects everyday cleaning. Place muddy paths, potting areas and heavily watered beds away from entrances where possible. If soil and mulch are regularly tracked indoors, choose an easy-care surface for nearby rooms and compare practical options in this flooring guide. Good garden design should make harvesting convenient without creating extra household maintenance.

Keep The Calendar Flexible

Weather is the final decision-maker. A late frost, unusually wet autumn or sudden heatwave can make a recommended date unsuitable, so check the seven-day forecast before transplanting. Delay sowing if the soil is waterlogged, and protect young plants when extreme temperatures are expected.

Choose healthy seedlings, refresh tired potting mix and keep paths, tools and beds organised as the season changes. Start with a few reliable crops, observe how they perform, then expand the garden with varieties suited to your conditions. Use this Australian gardening calendar as a working reference, mark the next planting window in your diary and begin preparing the bed before the ideal month arrives.
