Lawn fungus or brown spots — Amsterdam, North Holland
Brown, yellow, or dead patches appearing on your lawn — especially circular or ring-shaped patterns — often indicate a fungal disease rather than drought or insect damage. Common lawn fungi include brown patch (Rhizoctonia), dollar spot, fairy ring, and snow mold. Fungal infections typically strike when warm days combine with humid nights and poor air circulation. Over-watering, excessive nitrogen fertilization, and mowing too short all increase vulnerability. Early intervention is critical: a small brown patch can spread across an entire yard within 1–2 weeks under favorable conditions. Professional diagnosis ($50–$150 for a lawn inspection) identifies the specific fungus and treatment — fungicide applications run $100–$300 per treatment, and most lawns need 2–3 applications spaced 14–21 days apart.
Why this is common in Amsterdam
Amsterdam's outdoor spaces are primarily courtyard gardens, rooftop terraces, and balcony plantings that require specialized urban gardening knowledge. The city's verdant canal-side plantings require careful management within heritage guidelines.
