Disease Management

Lawn Diseases in New Zealand

New Zealand’s climate creates ideal conditions for a range of lawn diseases—most of them caused by naturally occurring fungal spores that lie dormant in the soil until the right weather triggers rapid growth. When conditions shift, these spores can activate quickly and spread across your lawn.

Common NZ Conditions That Trigger Lawn Disease
-Warm, humid summer periods
-Cool, damp autumn and winter conditions
-These conditions often lead to well‑known NZ lawn issues such as Red Thread, Brown Patch, Dollar Spot, Rust, and Melting Out

What increases the risk of lawn diseases?

Overwatering
Low soil pH
Poor soil nutrition
Mowing too short
Soil compaction and lack of aeration
Excessive thatch

When these factors combine with the right weather, disease can spread fast—causing thinning, discolouration, or dead patches.

Lawn assessment

Our LawnFix specialists carry out a detailed assessment of your lawn to identify the specific disease, contributing factors, and the overall health of your soil and turf. From there, we create a customised treatment and prevention plan designed to:

-Stop the disease from spreading
-Restore lawn health and colour
-Strengthen your lawn’s resilience against future outbreaks

We take a targeted, “as‑required” approach to fungicides, applying them only when conditions or disease severity genuinely call for it.
