Diagnosing Brown Patches in a New Lawn

A year-old lawn in Taupo is developing brown patches despite regular watering. Without knowing the grass species or local conditions, pinpointing the cause requires investigation.

Common Culprits

• Fungal diseases—such as brown patch or dollar spot—thrive in specific temperature and moisture conditions.
• Insect damage—grubs, chinch bugs, or other pests feeding on roots.
• Chemical or urine burn—from fertilizer spills, herbicide drift, or pet urine.

Next Steps

Contact your local agricultural extension agent for a tissue and soil analysis. Accurate diagnosis ensures the right treatment—whether fungicide, insecticide, or simply adjusting cultural practices. Guessing wastes time and money.
