Essential Garden Tasks for Autumn

Preparing Your Soil for Planting


To kickstart your autumn gardening in Queensland journey, focus first on enhancing your soil’s quality. Begin by clearing the garden of weeds, rocks, and debris. Enrich the soil by incorporating organic matter such as compost, well-rotted manure, or leaf mould, which boosts nutrient content and improves soil structure. 

This not only enhances water retention and drainage but also supports robust plant growth. Additionally, testing and adjusting the pH level of your soil to between 6.0 and 7.0 can significantly affect the health of your plants, as most vegetables thrive in this range.

Mulching for Weed Control and Moisture Retention

Mulching is a critical step in maintaining a healthy garden. Apply a layer of organic mulch—such as sugar cane, grass clippings, or pine bark—to conserve water by reducing evaporation and run-off. This practice also suppresses weeds and, depending on the type of mulch, can add essential nutrients back into the soil.

For optimal results, lay mulch on moist soil and ensure it’s not in direct contact with plant stems to prevent rot. Remember to replenish fine mulch more frequently to avoid compaction and to ensure effective water infiltration.

Pruning Summer Growth Encourages Autumn Blooms

Pruning is vital for promoting healthy new growth and maintaining the shape of your plants. Use secateurs for small branches and deadheading flowers, which invigorates shrubs and flowering plants. For larger branches, opt for a pruning saw or a pole pruner for hard-to-reach areas. This not only helps in managing the plant’s form but also prevents damage from overgrowth during the colder months. 

After pruning, consider applying a nitrogen-rich fertiliser if signs of nitrogen deficiency appear, as organic mulch can sometimes deplete nitrogen levels in the soil.

Best Vegetables to Plant in Autumn

Leafy Greens - Full of Health Benefits

Spinach for Queensland Autumn Gardening

Leafy greens, such as kale and spinach, are not just for summer salads. Autumn presents an ideal opportunity to grow these nutrient-rich vegetables in your Queensland garden. 

Greens are packed with vitamins and phytochemicals, offering protection against colds and flu during the cooler months. Moreover, they are low in calories, making them a perfect addition to hearty autumn meals. You can enjoy them sautéed with a bit of garlic, sea salt, and pepper, or even blend a handful into a smoothie for an easy nutrient boost. 

The varieties that thrive in autumn include spinach, rocket, endive, and kale, among others.

Root Vegetables - Great for Hearty Autumn Meals

Root vegetables like beetroot, carrots, and radishes are excellent choices for planting in autumn. These veggies not only withstand the cooler temperatures but also contribute to creating robust and flavourful dishes. 

Beetroot and carrots, in particular, can be sown now to produce a tasty treat just in time for winter. Additionally, planting root vegetables in autumn takes advantage of the moist soil from summer rains, supporting healthy growth. 

Don’t forget to water them regularly and provide a little help from natural fertiliser to ensure your root veggies flourish.

Legumes - Dietary Protein For Us, Healthy For Soil

Integrating legumes into your autumn garden offers dual benefits: they enrich the soil by adding nitrogen, and they provide a valuable source of dietary protein. 

Cowpeas and lablab are among the main summer legume fodder crops in south-east Queensland, ideal for planting in autumn. They not only improve soil fertility but also contribute to a more sustainable garden ecosystem. 

For those with an interest in perennial species, burgundy bean and butterfly pea are suitable options. Butterfly pea, in particular, is well-suited to Queensland’s clay soils and tolerates mild frost, making it a resilient choice for autumn planting. 

To ensure these legumes contribute effectively to soil health, it’s beneficial to include them in rotation with other crops or as part of a mixed pasture.

Plants That Thrive in Cooler Times

Beautify With Ornamentals

Cineraria - gardening in queensland
Alyssum - gardening in queensland

In cooler climates, including Queensland’s autumn season, a variety of ornamental flowers can significantly enhance the beauty of your garden. 

Consider planting alyssum, aurora daisy, cineraria, cornflower, cyclamen, English daisy, French marigold, Iceland poppy, lobelia, lupin, pansy, polyanthus, primula, snapdragon, stock, strawflower, sweet pea, and viola. 

These flowers not only add a splash of colour but also thrive in the cooler temperatures, making your garden a picturesque landscape even as the weather turns.

 For those with a creative flair, experimenting with the combination of these flowers’ shapes and colours can transform your garden from one season to the next.

Attract Wildlife with Native Flowers

Incorporating native flowers into your garden not only beautifies the space but also plays a crucial role in attracting and supporting local wildlife. By establishing layers of vegetation, from ground covers like leaf litter and grasses to taller trees with hollows, you create a habitat for diverse animals. 

Planting native species such as cut leaf daisy, creeping boobialla, fan flower, native violet, blue flax, knobby club rush, mat rush, guinea vine, pandorea, sarsaparilla vine, bottlebrush, coastal rosemary, grevillea, lilly pilly, swamp banksia, tea tree, thyme honey myrtle, banksia, and blush satinash, you’ll attract bees, birds, butterflies, lizards, and even frogs to your garden. 

These plants are adapted to local conditions, requiring less attention and thriving in the correct environment, thus supporting a sustainable ecosystem.

Perennials vs Annuals

Campanula - Gardening In Queensland

When deciding between perennials and annuals for your garden, it’s essential to understand their life cycles and how they can impact your garden’s appearance. 

Perennials, which include plants like anemones, astilbe, bergenia, and campanula, live for three years or more. They may not bloom as spectacularly as annuals, but they provide a sense of continuity and require less attention once established. Perennials can be a great drought-resistant choice and attract pollinators to your garden without the need for replanting every year.

On the other hand, annuals complete their life cycle in one growing season, often flowering nearly constantly to spread as much seed as possible. This provides stunning, season-long colour to your garden.

Depending on your climate, some perennials can act like annuals, so it’s crucial to consider your local hardiness zone when making your choice.

Autumn lawn care Tips

Aeration and Dethatching for a Healthier Lawn

Turf Aeration - Gardening in Queensland

To ensure your lawn remains healthy through Queensland’s cooler months, start with turf aeration and dethatching. Aerate the soil to alleviate compaction, allowing air, water, and nutrients to reach the grass roots effectively. This is crucial as compacted soil can starve the roots of essential elements. 

Following aeration, dethatching is necessary to remove the layer of dead grass and debris, which prevents moisture and nutrients from penetrating the soil. Aim to dethatch when the thatch layer exceeds 1.2 cm, typically in autumn for cool-season grasses

Choosing the Right Fertiliser

Selecting the appropriate fertiliser is vital for autumn lawn care. 

In South East Queensland, it’s recommended to avoid fertilising just before the wet season, making autumn an ideal time. Use a high-analysis fertiliser that is rich in nitrogen to boost colour and potassium to strengthen roots. 

For an organic approach, consider options like bat guano or compost, which provide a slower release of nutrients and are less likely to harm nearby groundwater.

Overseeding to Repair Patchy Areas

Autumn is the perfect time to overseed your lawn, especially to repair any worn or patchy areas. This process involves spreading new grass seeds over existing grass to enhance density and appearance. 

Before overseeding, ensure any compacted soil is aerated and any thick thatch is removed. Use a seed that matches your current lawn type and consider a starter fertiliser to support seed germination. 

Regular watering is crucial to maintain soil moisture until the new seeds sprout.

preparing Your Garden for winter


As the cooler months approach in Queensland, it’s essential to prepare your garden for winter to make sure its survivies and flourishes in the coming seasons.

Here are some steps you can take, focusing on protecting plants from early frost, storing garden tools and equipment efficiently, and setting up rainwater collection systems.

Protecting Plants from Early Frost

The Impact of Frost

Frost occurs when temperatures fall below 0°C, causing moisture in the air or ground to turn into ice, which can damage the water inside plant tissues.

Frost hardy Plants

In cooler parts of Australia, including Queensland, broad beans, garlic, spring onions, and various brassicas are more tolerant of frosts.

Perennials like artichokes and deciduous fruit trees also show good frost tolerance.

microclimate shelters

Create microclimates by sheltering less hardy species under tree canopies or planting on higher, warmer points in the garden, as frosts are often worse in low-lying areas

Cover plants overnight with materials like cardboard boxes or bed sheets. For prolonged frost exposure, consider semi-permanent solutions like a dome created with poly-pipe, covered with shade cloth or plastic

Watering Before Frost

Interestingly, a well-watered plant is more likely to survive frost. More water in the soil means more warmth, so it will take longer to freeze

storing garden tools and equipment


As the cooler months approach in Queensland, it’s essential to prepare your garden for winter to make sure its survivies and flourishes in the coming seasons.

Here are some steps you can take, focusing on protecting plants from early frost, storing garden tools and equipment efficiently, and setting up rainwater collection systems.


Maximise the use of your garden shed by implementing smart storage solutions. Utilise garden benches with lids for storing small tools and empty pots. An upright garden cupboard can store larger tools like spades and forks

Use Space Wisely

Consider additional storage options like the Keter outdoor storage box for extra garden essentials. Ensure that heavy items like bags of potting mix or fertiliser are stored on waist-high shelves to minimise bending

Set Up Rainwater Collection Systems


As the cooler months approach in Queensland, it’s essential to prepare your garden for winter to make sure its survivies and flourishes in the coming seasons.

Here are some steps you can take, focusing on protecting plants from early frost, storing garden tools and equipment efficiently, and setting up rainwater collection systems.

Government Initiatives

The Queensland Government has introduced initiatives making rainwater tank installation a focus in the building industry. This includes ensuring you have the best building practice in mind for tank installation

Installation Guidelines

When installing a rainwater tank, consider the roof area and location to maximise water collection. Tanks can be made from various materials, including polyethylene and concrete, and can be installed above or below ground depending on your needs

Regular Maintenance

Regular maintenance of your rainwater system is crucial to keep your water safe for all requirements around the home, especially for drinking. Ensure the system is designed for easy maintenance

By taking these steps, you can protect your garden from the harsher elements of winter, ensure your tools and equipment are well-organised and ready for the next season, and set up an efficient rainwater collection system to conserve water and reduce your bills.
