Lawn Care & Pest Management

Key Takeaways

• Healthy lawns start with nutrient-rich soil
• Strategic watering and mowing enhance lawn resilience
• Pest control should protect, not harm, the ecosystem
• Integrated approaches reduce reliance on chemicals
• Long-term lawn health depends on prevention

Building the Foundation: Soil & Nutrition

The health of any lawn begins below the surface. Healthy soil (soil rich in nutrients) creates the base for strong roots and durable growth. A balanced fertiliser schedule ensures lawns stay lush across the seasons.

At Searles Gardening, we recommend our specialised fertiliser solutions designed for Australian conditions. These blends encourage consistent growth and reduce the risk of deficiencies.

Lawn Care 101:

A healthy lawn begins with solid lawn care practices. Taking the time to properly establish and maintain your turf will not only improve its appearance but also make it more resilient to pests, diseases, and the often harsh climate.

1. Choose the Right Grass for Your Region

‍
With diverse climates, it’s important to choose the right type of grass for your region. Different grasses flourish in different conditions, and choosing the wrong one could lead to a weak lawn susceptible to pests and diseases. Here are some common grass varieties:

• Kikuyu Grass: Is better grown in southern cooler climates as a fast grower
• Buffalo Grass: Is a sun grass known for its soft texture.
• Couch Grass: A tough, heat-tolerant grass perfect for active yards or sports fields.
• Zoysia Grass: Suitable for cooler climates and drought-resistant.

By selecting a grass type suited to your climate, you’ll set the foundation for a healthy, pest-resistant lawn.

2. Regular Mowing

‍
Mowing your lawn is essential for maintaining its health, but how you mow is just as important. Cutting your grass too short can damage the roots and make your lawn more susceptible to weeds and pests. Aim to mow your lawn to a height of around 3–5 cm (depending on the grass variety), leaving enough blade length to protect the soil from extreme heat or cold.

Tip: Never mow more than one-third of the grass height at a time to avoid stressing the lawn.

3. Watering Properly

‍
Watering your lawn deeply and infrequently is better than shallow, frequent watering. Deep watering promotes stronger root growth, helping your lawn endure dry periods. Watering in the early morning is ideal, as it gives grass time to dry before evening and reduces the risk of fungal diseases.

Tip: In hot, dry weather, water your lawn at least twice a week. In cooler months, reduce watering frequency.

4. Fertilisation

‍
Fertilising your lawn is vital for keeping it strong and healthy. Using the right type of fertiliser based on the season will promote root growth, vibrant colour, and resistance to pests. During the warmer months, a nitrogen-rich fertiliser is ideal, while in cooler months, a slow-release fertiliser that includes potassium and phosphorus will help maintain root health.

Tip: Don’t over-fertilise, as this can burn the grass and attract unwanted pests. For an easy option, try Searles Lawn Food, specially blended to green up your lawn fast while delivering the nutrients it needs for long-term strength and resilience.

Pest Management: Protecting Your Lawn

Pest management is just as important as lawn care when it comes to maintaining a healthy yard. Lawns can be susceptible to a variety of pests, from grubs and ants to lawn beetles and more. Identifying and managing these pests early on can help prevent long-term damage.

1. Common Lawn Pests

‍

• Grubs (such as the Armyworm or Curl Grub): These pests feed on grass roots, causing patches of dead or yellowing grass.
• Lawn Beetles: The larvae of these beetles chew through grass blades, causing unsightly holes in the lawn.
• Ants: While not always directly harmful to grass, ants can create unsightly mounds in the lawn and sometimes promote fungal growth.

2. Prevention Is Key

‍

• Healthy Lawn, Healthy Defence: A thick, well-maintained lawn is your first line of defence against pests. Grasses with strong roots are less likely to be targeted by pests.
• Regular Lawn Inspections: Check your lawn regularly for signs of pests, such as wilting grass, patches of dead or yellowing turf, or visible insects. Catching the problem early can save you a lot of hassle later.

3. Chemical Treatments (When Necessary)

‍
While organic methods work well for minor infestations, some situations may require chemical treatments. If you have a significant pest problem, insecticides or pesticides may be necessary. It’s important to choose products that are safe for your lawn, pets, and the environment.

Tip: Always follow the instructions on the product label and apply during the early morning or late evening to minimise harm to beneficial insects like bees.

4. Lawn Aeration

‍
Aerating your lawn involves creating small holes in the soil to allow air, water, and nutrients to penetrate deeper into the root system. This process helps your lawn recover from pest damage and promotes healthy grass growth. Aerating can also help reduce compaction, which often invites pests like grubs to settle in.

Tip: Aerate your lawn once a year, preferably in spring or early autumn, when the grass is actively growing.

Final Tips for a Healthy, Pest-Free Lawn

• Keep a Balance: Lawn pests are more likely to invade stressed lawns, nutrient-poor lawns, or droughted and water logged lawns. Maintaining the right balance of nutrients suitable for lawns helps prevent stress and promotes healthy grass.
• Keep the Lawn Clean: Remove any fallen leaves, dead grass, and garden debris regularly. These materials can attract pests and provide hiding places for insects.

Regular monitoring and early treatment with suitable pest control products help prevent lawn grubs from spreading.

Can overwatering damage my lawn?

‍
Yes. Overwatering encourages shallow root growth and increases the risk of fungal disease in lawns.

Are chemical pesticides safe for pets?

‍
Most approved products are safe when used correctly, but always follow label directions and keep pets away until the lawn is dry.

What lawn height is best for grasses?

‍
A height of 3–5 cm is generally recommended, though some warm-season grasses may need slightly more.

How do I prevent fungal lawn diseases?

‍
Ensure proper drainage, avoid overwatering, and mow at the correct height to reduce the likelihood of fungal growth.
