How To Get Rid Of Weeds In Lawn

17 Apr How To Get Rid Of Weeds In Lawn

Weeds have a way of sneaking into even the healthiest-looking lawns. One minute, your grass looks thick and green, and the next, you’re spotting strange leaves, bare patches, and fast-growing invaders stealing the spotlight. While weeds are frustrating, the good news is they’re manageable with the right approach.

This guide walks you through how to get rid of weeds in your lawn, why they appear, and long-term prevention and maintenance tips that’ll keep your lawn looking fresh and clean.

Common Types of Lawn Weeds in Australia

Weeds come in different shapes and sizes. Here’s a brief breakdown of some common Australian weeds to look out for.

Why Do Weeds Appear?

Weeds may look like they just appear out of thin air, but there’s a lot that goes into their formation. Let’s explore some common reasons why weeds appear in the first place.

Soil Compaction

Soil compaction occurs when soil particles are pressed together, reducing the space between them. This can be due to dense soil, heavy foot traffic on your lawn, or not aerating your lawn. 

Compacted soil restricts air, nutrients, and water from reaching your lawn, leading to your lawn thinning out or even dying. As a result, weeds take advantage of this, especially those that are tolerant of compacted soil.

Not Overseeding

Lawns are greatly susceptible to weather damage, such as extreme heat or snow. Overseeding helps repair bare patches and improve lawn density without removing any existing grass. However, failure to do this leaves room for weeds to grow in the thinning areas.

Lawn Scalping

Lawn scalping means mowing your lawn at a low height. While this may be beneficial in keeping your lawn tidy and free from thatch and debris, overdoing it can also lead to weed growth. Over-scalping can lead to weakened grass, increased soil exposure, and root damage, allowing weeds to germinate and compete for nutrients.

How to Get Rid of Weeds Naturally

Taking a natural approach to weed control helps protect your lawn, soil health and the surrounding environment. These methods work best when applied consistently to your regular turf care and maintenance routine.

Remove Them Manually

Hand-pulling weeds is one of the most effective natural methods, especially for small infestations. Aim to remove the entire root system to prevent regrowth, ideally after rain or watering when the soil is soft. 

For stubborn weeds, a simple hand weeding tool can make the job quicker and more precise without disturbing nearby turf.

Improve Lawn Density

A thick, healthy lawn is your best defence against weeds. Dense turf leaves little room for weed seeds to settle and germinate. Regular watering, correct mowing height and seasonal fertilising all help encourage strong turf growth that naturally crowds weeds out.

Add Mulch to Bare Areas

Bare patches are prime real estate for weeds. Applying organic mulch such as bark chips or compost helps suppress weed growth by blocking sunlight while also improving soil quality. This is especially useful around garden edges, pathways and newly laid turf areas.

Aerate Soil Regularly

Compacted soil creates stress for turf and gives weeds an advantage. Aerating your lawn improves airflow, water absorption and nutrient penetration, helping grass roots grow deeper and stronger. Healthier turf recovers faster and is far less likely to be overtaken by weeds.

Create a Natural Weed Spray

For spot treatment, a natural weed spray made from household ingredients like vinegar, water and a small amount of dish soap can be effective. Apply carefully and only to the weed itself, as these solutions are non-selective and can harm surrounding grass if overused.

Solarisation

Solarisation involves using a clear or black plastic sheet to trap the sun’s heat in the soil, effectively “baking” the weeds until they die. This is especially useful against weeds that are most active in summer, such as crabgrass or goosegrass.

Keep your soil moist by watering it thoroughly, as moist soil is a better heat conductor. Lay the sheet flat on the ground, clear of any extra debris or rocks. Seal the edges to prevent heat from escaping, and leave it for about 4 to 8 weeks.

Weed Prevention and Maintenance Tips

Preventing weeds is always easier than removing them later. A proactive maintenance routine keeps your lawn looking lush and weed-free year-round.

Mow Correctly and Consistently

Mowing too short weakens turf and exposes soil to weeds. Keep your mower blades sharp and mow at the recommended height for your turf variety. Consistent mowing encourages even growth and helps shade out emerging weeds.

Fertilise Regularly

A well-fed lawn grows stronger and recovers faster from wear and tear. Use a high-quality fertiliser suited to your turf type and apply it during active growing seasons. Balanced nutrition supports dense growth and reduces opportunities for weeds to establish.

Maintain Soil pH and Drainage Levels

Poor soil conditions often lead to weed problems. Test your soil pH and adjust it if necessary to suit your turf variety. Ensure proper drainage to avoid waterlogging, which can stress grass and encourage unwanted plant growth.

Address Bare Patches Early

Small bare spots can quickly turn into weed hotspots if ignored. Repair these areas early by topdressing with quality soil or laying fresh turf. Prompt action helps maintain a uniform lawn and keeps weeds from gaining a foothold.

Consult Seed and Turf for Professional Weed Control
