As the vibrant hues of summer give way to the golden tones of autumn, many Australian gardeners find themselves in a perennial battle against an unwelcome guest: weeds. While the cooler months can provide a much-needed respite from the heat, they also create the perfect breeding ground for a variety of pesky plants that threaten to invade your well-maintained lawn. But fear not, green-thumbed friends! With a little know-how and some timely intervention, you can protect your patch of green from these autumnal adversaries.
The shift from summer to autumn brings significant changes to your garden’s ecosystem. Grass growth slows as the days shorten and temperatures drop, and your lawn begins to prepare for the winter dormancy ahead. This involves a shift in energy from leaf production to root strengthening, which is essential for surviving the colder months. However, this natural transition also opens the door for weeds to take hold.
Weeds are opportunistic by nature, and they’ll seize any chance to establish themselves. During autumn, the combination of cooler weather and increased rainfall in many parts of Australia creates an ideal environment for weeds to flourish. Without the vigorous growth of lawn grass to compete with, weeds can easily spread and become a dominant force in your garden.
Before you can effectively combat these invaders, you need to know what you’re up against. Some of the most common autumn weeds include winter grass and broadleaf weeds such as thistle, dandelion, creeping oxalis, clover, bindi eye, and sour sob. Each type of weed requires a specific approach to control and eradication.
Autumn is not only a time for weed control but also an opportunity to nourish your lawn. Weed and feed products can be particularly effective during this season. They simultaneously eliminate weeds and provide essential nutrients to your grass, aiding in recovery from summer stress and preparing it for winter.
When selecting a weed and feed product, it’s crucial to choose one that’s appropriate for both the type of weed you’re targeting and the species of grass in your lawn. This ensures that you’ll eradicate the weeds without harming your grass.
For small patches of winter grass, hand pulling can be an effective method, especially when the soil is moist. Ensure you remove the entire plant, roots and all, to prevent it from coming back. For larger infestations, selective herbicides designed to target winter grass can be used. Products like Munns Professional Winter Grass Killer are safe for various lawn types, including Kikuyu, Buffalo, Couch, and Queensland Blue Couch. Always read the label and follow the manufacturer’s instructions when using herbicides.
Similarly, broadleaf weeds can be managed through hand-pulling or the use of selective herbicides. These come in sprays, granules, and concentrates, and are most effective when the weeds are actively growing.
To keep your lawn healthy and resilient against weed invasions, consider these autumn lawn care practices:
- Top dress your lawn: Apply a thin layer of soil, compost, or a blend of both to improve soil quality and promote healthy grass growth.
- Fertilise now: A good feed will help your lawn recover from summer and strengthen it for the colder months ahead.
- Aerate the lawn: This helps alleviate soil compaction, allowing water, nutrients, and air to reach the roots, which can be particularly beneficial for repairing bare patches.
Keeping your lawn healthy and weed-free during autumn requires a proactive approach, but with the right strategies, you can stay ahead of these seasonal invaders. Every garden is unique, and different methods work for different lawns.
