Common Winter Lawn Problems in Adelaide

Common winter lawn problems in Adelaide tend to fall into three categories: shade, poor drainage and weeds. Understanding what causes each one and the winter lawn care mistakes that may let them take hold is the first step to avoiding them next season.

Throughout Winter, we get hundreds of people coming into our store asking us to help solve problems. We also have the privilege of going out to customers homes to help resolve more complicated issues. We’ve seen some common themes come up - with some planning, many of these ails can be avoided next Winter, leading to healthier lawns to enjoy.

Let me take you through some of them and give you some helpful hints. As you’ll come to see, many of these issues can be prepared for in the Autumn so that their effects are not so severe in the Winter.

Shade: A Common Cause of Winter Lawn Problems

Interestingly, shade is a significant factor in how lawns degrade over Winter. With the sun lower in the sky, areas that did receive full sun no longer do, which can be a problem for lawns like Kikuyu and couch. Even shade-tolerant lawns like buffalo can have issues here. One of the most significant issues with shade is that it creates ideal conditions for moss and algae to grow. Shade, accompanied by moss and algae, were huge culprits of making lawns look poor this year, compounded by the extra rain we had. If you were to do one thing next Winter – monitor your lawn for moss and algae and treat it when you see it. For more information, read our blog on moss and algae control in lawns

• Have a look and see if there are any opportunities to increase the level of sun through Winter. While shade created by buildings and fences can’t be affected, you may be able to lift the canopy on a tree or remove some unnecessary vegetation.
• Be aware that shade creates ideal conditions for moss and algae to thrive. Be prepared to tackle that when you see it. Typically, two applications of a moss killer called Wet and Forget would be enough to keep it at bay for the whole Winter. 

Poor Drainage: A Common Winter Lawn Care Mistake

We’ve had a lot of water this Winter – certainly more than we’ve had for a while. When water can’t drain away properly from your lawn, it will suffer. Most consultation visits we did this Winter had elements of drainage issues. When water sits in the soil for too long, it starves the lawn of oxygen, which will kill the lawn in time. For more information read our blog on managing drainage issues in lawns

• Take some photos of the waterlogged areas so that you remember where they are when it comes time to deal with them. Plan some time to correct drainage issues before next Winter arrives
• Coring and top-dressing help, as does installing drains to divert the water away

Weeds: Why They Take Over Adelaide Lawns in Winter

Many lawns get dominated by weeds during the Winter because they are not deal with properly during the Summer and Autumn. Common weeds like winter grass and broadleaf lie and wait in the form of seed in the soil until conditions are perfect for germinating and thriving. Because most lawns are dormant during Winter, they can dominate with little competition making for an unattractive lawn. Most of this can be avoided with the timed application of a pre-emergent herbicide called Spartan. Applied during March, it will stop most winter weeds from germinating, leading to a clean winter lawn. For more information read our blog on pre-emergent weed control in lawns 

• Apply Spartan any time in March for the control of winter grass and broadleaf weeds.

How Foot Traffic Can Affect Your Lawn in Winter

Beyond shade, drainage and weeds, foot traffic is another winter lawn care issue worth considering. During the colder months, warm-season grasses grow more slowly and have less opportunity to recover from wear and damage.

If you have a buffalo lawn, keep foot traffic - including pets, garden furniture, trampolines and trailers - to a minimum through the coldest months. Where an area gets regular use, consider stepping stones or a temporary path to redirect traffic away from the turf itself.

Reducing unnecessary traffic during winter can help minimise worn or patchy areas and give your lawn a better starting point when active growth returns in Spring.

Simply said, these were the most common issues we noticed this Winter, and I think regular and high amounts of rain compounded them. There are others, however, these were the ones we were dealing with the most. If you were unhappy with the performance of your lawn this Winter, have a go at dealing with the above. You might be surprised at the difference it makes. As always, if you have any issues you want help solving, give us a call on 0882980555 or send an email to stefan@paulmunnsinstantlawn.com.au.

Frequently Asked Questions

Why does my lawn get worse every Winter even though I don't do anything differently?

Winter problems compound over several seasons if the root cause isn't addressed. Shade increases as trees mature, drainage issues worsen as soil compacts over time and weed seed banks grow larger each year they're left untreated. Addressing the cause in Autumn - rather than just the symptom in Winter - is the only way to break the cycle.

Is it too late to fix drainage or shade issues once Winter has started?

You can still identify and plan for these issues during Winter, but most physical fixes (coring, top-dressing, pruning trees, installing drainage) are best carried out from late Winter into Spring when the lawn is starting to grow again and can recover from the work.

Will one bad Winter mean permanent damage to my lawn?

Not usually. Warm-season lawns will generally begin recovering as temperatures rise and active growth returns in Spring. However, prolonged waterlogging, heavy traffic or other ongoing problems can lead to areas that take longer to recover.

What's the single most common issue you see in Adelaide lawns each Winter?

Drainage-related patchiness can be a common issue in Adelaide lawns during winter, particularly following periods of consistent or heavy rainfall. Waterlogged soil starves lawn roots of oxygen, which shows up as browning or thinning in low-lying or heavy-clay areas.
