Why is my lawn dying?

1. Extreme weather conditions

This is an obvious one for Brisbane locals. Changes in temperature, humidity and excessive rainfall can all cause your grass to react differently. Heat and excessive rain can both be big problems in a subtropical climate like Brisbane.


During periods of extreme heat, the grass will likely suffer from drought stress. This can cause the grass to turn brown and become more susceptible to disease. It can also cause the soil to dry out, making it more difficult for the roots to uptake water and nutrients.
  • Action: Aeration + Seeding
Aeration works to break up compacted turf by creating little plugs of soil. Overseeding the lawn with the right grass seeds will encourage new growth in the aeration holes. Before you know it, your lawn will be looking green and lush again.

Excessive rain

Excessive rain can have a negative impact on the quality of your grass. Too much water can cause the grass to become waterlogged, which can lead to a host of problems. This includes disease, fungal growth and root rot. Prolonged periods of wet weather can make it difficult for grass to get the oxygen it needs. This leads to problems with blade growth and colour.
  • Action: Drainage + Aeration
Drainage systems and aeration will help remove excess water from your lawn. By taking these steps, you can help ensure that your grass stays healthy and vibrant, even in periods of excessive rainfall. Another tip to restore your once green oasis, is replenishing your grass with essential nutrients. image of a person weeding a dying and brown lawn for why is my lawn dying

2. Weeds and Pests

Weeds compete with grass for nutrients, sunlight and water. Over time, this can result in thin, patchy grass that is more vulnerable to disease and insect damage. Pests can also cause direct damage to grass by eating the blades or roots. In severe cases, this can kill the grass entirely.
  • Action: Mowing + Watering + Herbicide + Insecticide
Regular mowing and watering help to discourage weed growth. Applying herbicides or pesticides can help to control existing problems. By addressing the problem and taking preventative measures, you can revive a dead lawn. And you will be able to keep it thriving for years to come.

4. Compact soil

If you’re asking why is my lawn dying, compact soil could be the answer. When the soil is compacted, it prevents air and water from circulating properly, which can kill your lawn. There are a few tell-tale signs. They include bare patches, yellowing grass and thinning turf. If you suspect that your soil is compacted, there are a few things you can do to fix the problem.
  • Action: Add Organic Matter + Aeration
First, aerate the soil to improve the circulation. You can also add organic matter, such as compost, to help break up the compacted soil. Or you can feed it ECO 88 Lawn Food by Queensland Organics. Queenslanders love their lawn, and this can sometimes manifest in over-watering or over-fertilising. This can contribute to compaction so it’s worth creating a healthy maintenance routine. image of brown grass with a tree along the sidewalk for why is my grass dying

5. Neglect

Neglect is one of the most common lawn killers. It may seem like a hassle to mow, fertilise and water on a regular basis but these activities are essential for maintaining a healthy lawn. Without proper care, grass quickly becomes yellow and patchy, and weeds begin to take over.
  • Action: Some Tender Loving Care
Mow your lawn at least once a week during the growth season. Give your grass a decent haircut but nothing too crazy! If the grass is too short, it will be more susceptible to disease. If it's too long, it will be difficult to mow and may develop thatch. Water and fertilise when required. And don’t forget the underrated superstar of lawn care – aeration. green-turf
