Evaluation and Preparation

Before delving into autumn lawn care tasks, take a moment to assess the current condition of your lawn. Look out for any signs of damage, disease, or nutrient deficiencies, addressing them promptly to prevent further deterioration as the season progresses. Additionally, clear your lawn of debris such as fallen leaves, branches, or clutter that may impede growth.

In autumn, adjust your mowing routine to accommodate the slower growth rate of grass. Raise the cutting height of your mower slightly to help the grass retain more moisture and endure cooler temperatures. Aim to maintain a consistent lawn height, typically between 2.5 to 3 inches, to encourage healthy growth and deter weed formation. For expert assistance, reach out to Lawn Rite – the specialists in lawn care.


Autumn presents an ideal opportunity to aerate your lawn, especially if it experiences heavy foot traffic or compaction issues. Aeration helps alleviate soil compaction, enhances water and nutrient absorption, and stimulates root development. While various lawn aeration tools are available, not everyone has the time or energy for this task. If you require assistance with lawn aeration, contact Lawn Rite for support.


Overseeding during autumn can aid in filling bare patches and thickening your lawn. Select a high-quality grass suitable for your region and existing turf type. Prior to overseeding, aerate the lawn to create openings for the new seeds to take root. Follow up with regular watering to facilitate proper germination and growth.


Applying a slow-release fertiliser in autumn supplies essential nutrients to sustain your lawn’s health during the cooler months. Opt for fertilizers specifically formulated for autumn application, with a balanced ratio of nitrogen, phosphorus, and potassium. Adhere to the manufacturer’s instructions meticulously to prevent over-application, which can result in nutrient runoff and environmental harm.

Weed Management

Autumn presents an opportune time to address weeds before they establish themselves. Apply a selective herbicide to target broadleaf weeds while safeguarding the grass. Ensure to select a product compatible with your specific grass type and adhere to the application instructions rigorously for optimal efficacy.


Despite increased rainfall in autumn, it’s important to monitor soil moisture levels and supplement with watering as needed. Strive for deep, infrequent watering sessions rather than frequent shallow watering, as the latter can encourage shallow root growth and fungal infections. Water in the early hours of the day to allow the grass to dry before nightfall, reducing the risk of disease.

By adhering to these autumn lawn care guidelines tailored to New Zealand’s climate and conditions, you can preserve a lush, well-maintained lawn that enhances the beauty of your outdoor environment. Remember to adjust your lawn care regimen as the season progresses and remain proactive in addressing any issues that arise. With proper care and attention, your lawn will flourish throughout autumn and beyond, providing a picturesque backdrop to enjoy year-round.
