How to care for your lawn in winter

Winter can be a tough season for maintaining a lush and healthy lawn. As temperatures drop and frost settles in, adapting your property's lawn care routine is crucial to ensure your grass stays vibrant and resilient. This guide will walk you through essential winter lawn care tips to help you keep your property's yard in top shape throughout the colder months. Read on to learn more!


Understand your lawn's winter dormancy

Recognise dormancy signs

During winter, many grass types enter a dormant state to conserve energy. You might notice your lawn turning brown or yellow but don't worry – this natural process helps the grass survive harsh conditions. Dormancy is the grass's way of going into hibernation mode, which reduces its growth and activity, conserving resources for better weather.


Learn about grass types

Different grass types behave differently in winter. Cool-season grasses like ryegrass and fescue remain active, growing slowly even in cooler temperatures. However, warm-season grasses like Bermuda grass and zoysia go fully dormant, turning brown until warmer weather returns. Understanding your grass type helps you tailor your winter care practices effectively.


Know why dormancy helps

Dormancy protects your lawn from the harsh winter conditions. The grass can survive low temperatures and reduced sunlight by slowing down growth. It's a natural defence mechanism that ensures the lawn doesn't expend unnecessary energy during a period when growth conditions are less than ideal. This energy conservation means your grass will be ready to bounce back vigorously when spring arrives.


Identify non-dormant areas

Some areas of your lawn, particularly those with more sunlight or better drainage, might not go fully dormant. Keep an eye on these spots and care for them as needed, providing a little more attention to ensure they stay healthy. These areas might still benefit from occasional mowing and light watering, even in winter.


Adjust expectations for winter

Understand that your lawn won't look as vibrant as it does in spring and summer. Adjust your expectations and focus on maintaining the grass's health for a strong comeback in spring. Winter is a time for maintenance and preparation rather than perfection, so don't be discouraged by the temporary change in appearance.


Adjust your mowing habits

Lower mowing height gradually

As winter approaches, gradually lower your mowing height. This helps the grass withstand the cold and reduces the risk of fungal diseases. Lowering the height in stages prevents shocking the grass, which can be more vulnerable during seasonal transitions.


Avoid mowing wet or frozen grass

Mowing wet or frozen grass can damage the blades and roots. If needed, wait for a dry, unfrozen day to mow. Wet grass is more susceptible to disease; mowing it can spread fungal spores, leading to lawn issues.


Keep mower blades sharp

Sharp mower blades ensure clean cuts, reducing stress on the grass. Dull mower blades tear the grass, making it more susceptible to disease. Regularly sharpen your mower blades to keep them in top condition, ensuring your lawn stays healthy.


Clear leaves before mowing

Eliminate fallen leaves and debris from your lawn before mowing. This prevents smothering the grass and reduces the risk of disease. Leaves can block sunlight and trap moisture against the grass, creating a perfect environment for fungi and other pathogens.


Mow less frequently

Grass growth slows in winter, so you won't need to mow as often. Keep an eye on the growth and mow only when necessary. Overmowing can stress the grass and contribute to thinning, so it's best to mow sparingly during the colder months.


Manage lawn traffic carefully

Limit traffic on frosty grass

Walking on frosty or frozen grass can cause damage. The grass blades are brittle and can break, leading to dead patches. Encourage family members, close friends and guests to use designated pathways or avoid the lawn when it's frosty.


Create pathways to reduce damage

Designate pathways for regular foot traffic to minimise damage to the lawn. This is especially important during parties or gatherings. To protect the grass, temporary pathways can be created using mulch or stepping stones.


Inform family about lawn care

Educate your family, close friends and guests about the importance of staying off the lawn during frost. This simple step can prevent significant damage. Understanding and cooperation from everyone who uses the lawn can make a big difference in its winter health.


Repair damage quickly

If areas of your lawn do get damaged, repair them promptly. Re-seed or patch the spots to prevent further issues in spring. Quick repairs help the lawn recover faster and reduce the chance of weeds taking over the damaged areas.


Use barriers for pets

Pets can also damage your lawn during winter. Set up barriers or designate specific areas for them to play, keeping the rest of the lawn intact. Training pets to use a particular area can help protect the grass and keep it looking its best.


Fertilise appropriately for winter

Use winter-specific fertiliser

Choose a fertiliser formulated for winter use. These fertilisers have the right balance of nutrients to support your lawn during the cold months. Look for products that provide slow-release nitrogen, which feeds the grass steadily without promoting excessive growth.


Apply before the first frost

Applying fertiliser before the first frost allows the nutrients to deeply penetrate the soil and reach the grassroots, strengthening them for winter. This timing ensures that the grass can absorb the nutrients effectively before growth slows down.


Follow application rates

Be sure to follow the recommended fertiliser application rates on the package. Over-fertilising can harm your lawn and the environment. Excess fertiliser can lead to nutrient runoff, pollute water sources, and disrupt local ecosystems.


Lightly water after fertilising

After applying fertiliser, water your lawn lightly. This helps the nutrients soak into the soil and reach the roots more effectively. Light watering ensures that the fertiliser is activated and begins to nourish the grass.


Consider organic options

Organic fertilisers are a sustainable choice and can improve soil health over time. Look for options that suit your lawn's needs. Organic products often provide a balanced range of nutrients and improve overall soil structure and microbial activity.


Water wisely during winter

Reduce watering frequency

As temperatures drop, your lawn needs less water. Reduce your watering frequency to prevent overwatering and root rot. Overwatering can create waterlogged conditions that harm the grass and promote disease.


Water in the morning

Water your lawn in the morning to give it time to absorb the moisture before evening temperatures drop, reducing the risk of freezing. Morning watering also allows the grass to dry out evenly during the day, minimising fungal growth.


Check soil moisture

Before watering:


  • Check the soil moisture.
  • If the soil is still damp, avoid watering to avoid water logging and disease.
  • Use a soil moisture metre or feel the soil with your fingers to gauge moisture levels.

Use a rain gauge

Monitor natural precipitation with a rain gauge. Adjust your watering schedule based on rainfall to avoid overwatering. A rain gauge helps you track how much water your lawn receives from natural sources.


Avoid overwatering

Overwatering could lead to adverse issues like root rot and more. Ensure you're providing just enough water to keep the grass healthy without causing damage. Proper watering practices promote deep root growth, making the lawn more resilient.


Protect your lawn from pests and diseases

Identify common winter pests

Common winter lawn pests in Australia include grubs and certain types of beetles. Knowing what to look for can help you address issues promptly. Look for signs of pest activity, such as chewed grass blades or mounds of soil.


Inspect regularly

Regular inspections can catch pest infestations early. Look for signs like chewed grass blades or unusual patches of dead grass. Early detection allows for targeted treatments and prevents widespread damage.


Apply pest control as needed

If you spot pests, use appropriate treatments to control them. Follow the treatment instructions carefully to avoid harming your lawn. Consider using natural or biological control methods to minimise environmental impact.


Keep lawn clean from debris

Eliminate fallen leaves, twigs, and other debris from your lawn. These can create hiding spots for pests and contribute to disease. A clean lawn is less attractive to pests and reduces the likelihood of fungal infections.


Encourage healthy grass growth

A healthy lawn is more resistant to pests and diseases. Proper care and maintenance keep your grass in good condition. Healthy grass also competes better with weeds and is less susceptible to pest damage.


Prepare for spring

Aerate the soil in late winter

Aerating the soil in late winter helps improve air and water flow to the grassroots, preparing your lawn for spring growth. Aeration reduces soil compaction and promotes a healthier root system.


Overseed thin areas

If your lawn has thin or bare patches, overseed these areas in late winter. This gives the new grass time to establish before spring. Overseeding helps fill in gaps and improves the overall density of your lawn.


Plan early spring fertilisation

Start planning your early spring fertilisation schedule. This ensures your lawn has the needed nutrients to recover from winter dormancy. Early fertilisation supports vigorous growth as temperatures warm up.


Schedule mower maintenance

Make sure your mower is in top condition for spring. Sharpen the blades, check the engine, and perform any necessary maintenance. A well-maintained mower ensures clean cuts and reduces stress on your grass.


Mulch garden beds for protection

Mulching garden beds helps protect plants from winter cold and reduces weed growth. It also improves soil quality for the next growing season. Mulch acts as an insulating and protecting layer, stabilising soil temperatures.


Final thoughts

Winter lawn care can seem daunting, but with the right approach, it's entirely manageable. By understanding dormancy, adjusting mowing habits, managing traffic, fertilising correctly, watering wisely, protecting against pests and diseases, and preparing for spring, you can keep your lawn in great shape even during the colder months.
