1. Why Weeds Thrive in Narre Warren South

To control weeds effectively, it helps to understand why this suburb is such a hotspot.

1.1 Climate

Narre Warren South experiences:

• Mild to warm summers
• Cool, wet winters
• Regular rainfall spread across the year

This creates ideal weed-growing conditions, especially for species that thrive in moist soil, such as clover, capeweed and bindii.

1.2 Soil Type

Much of Narre Warren South is built on:

• Clay-based soil
• Poor drainage areas
• Low-organic-matter garden beds (in new estates)

Clay soil retains moisture, allowing many broadleaf weeds and invasive grasses to spread aggressively.

1.3 New Housing Estates

Newer estates often have:

• Imported turf
• Thin topsoil
• Soil disturbance from construction

This makes the ground highly vulnerable to fast-growing weed species.

A major pain for kids, pets, and anyone who loves walking barefoot on the lawn.

How to identify Bindii

• Small rosette-shaped leaves
• Tiny sharp prickles in summer

Best control methods

• Pre-emergent herbicides in early winter
• Selective broadleaf herbicides in early spring
• Regular mowing to prevent seed head development

---

2.2 Clover (Trifolium repens)

• Thrives in damp lawns

Control

• Improve soil nitrogen (fertilise regularly)
• Selective broadleaf weed killers
• Good lawn aeration

---

2.3 Dandelion (Taraxacum officinale)

A familiar yellow-flowered weed with deep taproots.

Identification

• Bright yellow flowers
• Long jagged leaves
