As autumn settles in, we see cooler temperatures, shorter days, and vibrant leaves in shades of red, orange, and gold. It’s also the perfect time to get your garden ready for winter. Autumn’s mild weather creates the ideal conditions for a range of gardening tasks that will ensure your garden is healthy and prepared for the colder months.
Whether you’re new to gardening or already have a green thumb, this is the best season to tackle important tasks like fertilising, pruning, planting, and improving soil health.
Why Autumn is the Best Time for Gardening Tasks
Autumn brings cooler temperatures and more consistent rainfall than summer, making it an ideal time to give your plants the attention they need before winter sets in. The soil is still warm from the summer months, providing an excellent environment for plant roots to establish. This season also offers less intense sunlight, allowing plants to acclimatise and recover without the stress of hot summer heat.

Autumn is the perfect time to fertilise your garden because the soil is still warm from summer, and plants are gearing up for their winter dormancy. Adding fertiliser now helps plants build strong roots before they rest during the colder months.Look for a specific autumn fertiliser that’s slow-release to support root growth, and apply it all over your lawn. Try to do this early in the season, as waiting until the cooler temperatures at the end can slow down the uptake of nutrients.
Prune trees and shrubs
Pruning in autumn encourages healthy growth for the following spring, and helps plants shed dead or damaged branches to allow new, strong growth to emerge. The cooler, calmer weather means there’s less risk of heat stress during this process.
Simply trim away dead or damaged branches from trees and shrubs. Be cautious not to prune too late in the season, as this can expose plants to frost damage.
Add mulch
Mulching in autumn helps soils to retain moisture, and provides insulation during the colder months. It’s a great way to protect plant roots from frost and keep the soil healthy.
At the beginning of autumn, apply mulch in a 5-7cm layer around your plants. Just avoid piling it directly against plant stems, as a lack of breathing room can cause them to rot. This is also a great way to tidy up your garden before winter.
Plant autumn veggies
Autumn is an ideal time to plant cool-season veggies, as the weather is mild and the soil is still warm. This gives your plants enough time to grow before the cold winter temperatures set in.
Wondering what veggies to plant now? Broccoli, cauliflower, garlic, kale, carrots, and cabbage thrive in autumn. This can, of course, depend on where you live in Australia, so check your local climate zone to find out what will grow best.
Spring bulbs
Set yourself up for a burst of colour in the spring by planting bulbs in autumn. As the summer comes to an end, soil is the perfect temperature for bulbs to establish roots, giving them a head start for the coming spring.
Choose spring-blooming bulbs like tulips, daffodils, and hyacinths, and plant them in well-drained soil with a little fertiliser to support their growth. For smaller spaces, consider planting bulbs in pots for a pop of colour on balconies or patios.
Autumn tree planting
Autumn is the ideal time to plant trees, as it gives them plenty of time to settle before the harsher summer months arrive. The cool weather also promotes root growth, helping trees to establish themselves.
When you’re choosing what trees to plant in autumn, consider native species like grevilleas, bottlebrush, and banksias, or even citrus trees such as lemons and oranges.
Improve your soil
With the summer heat at bay, now is the perfect time to get outside and work on improving soil health. Autumn’s moderate temperatures encourage soil microorganisms to break down organic matter, too, enriching your garden soil and giving it everything it needs to support strong plant growth.
By adding compost, mulch, manure, or organic matter, you’ll help to improve the soil structure so it can retain moisture and nutrients, providing a better environment for next season’s plants.
Water your plants
Although autumn brings cooler temperatures, plants still need regular watering, especially early in the season when it’s dry outside. Continue watering your garden as normal, and check your plants regularly to ensure they’re receiving enough water without being overwatered.
Rake and recycle leaves
With an abundance of leaves falling in Autumn, you’ll probably want to keep on top of tidying them! But, rather than bagging them up, use them to your garden’s advantage. Leaves make excellent organic mulch and compost, adding valuable nutrients to the soil.
Aerate Your Lawn
Aerating your lawn in autumn helps improve soil drainage, reduce compaction, and increase oxygen flow to plant roots. Simply use an aeration machine, aeration shoes, or a garden fork to core (create small holes) in the soil to allow for better air and water flow. Aerating will give your lawn the best chance to thrive when things start to heat up again in the spring.
Transplant plants
Autumn is a great time to transplant any plants that need a new home, as the cooler temperatures allow plants to adjust to their new location before the winter dormancy period begins.
Carefully dig up your plants, ensuring you take as much of the root ball as possible. Replant them in a location that provides the right sunlight and soil conditions, then water them well and give them a bit of fertiliser to get them started. Keep an eye on your transplanted plants in the coming weeks to ensure they’re settling in.
