Why Do Lawns Go Thin in Auckland?

Thin lawns are common across Auckland — especially in high rainfall and high growth areas.

Here are the most common causes.

1️⃣ Cutting Too Short

Scalping weakens root systems and opens space for weeds.

Correct mowing height is critical for cool-season grasses.

2️⃣ Poor Fertilising Timing

Nutrient deficiencies lead to weak, pale turf.

Without seasonal feeding, lawns gradually lose density.

3️⃣ Weed Pressure

Clover, oxalis, plantain and other broadleaf weeds compete for nutrients and space.

Thin lawns allow weeds to establish easily.

4️⃣ Soil Compaction

Heavy foot traffic and machinery compress soil, restricting oxygen and root growth.

5️⃣ Crown Grass Invasion

Crown grass spreads aggressively in weakened lawns and reduces turf uniformity.

How to Fix a Thin Lawn
