Common Lawn Problems in Plymouth
Persistent moss
High rainfall and mild winters make moss the dominant problem in Plymouth. Twice-yearly iron sulphate treatment (spring and autumn) is the minimum programme. Address root causes: improve drainage, reduce shade, and correct acidic soil.
Fusarium patch
Warm, wet conditions promote fusarium patch (salmon-pink circular patches) throughout much of the year in Plymouth. Improve airflow, avoid evening watering, and apply fungicide at first signs.
Waterlogging
Heavy winter rainfall saturates soils for weeks. Annual hollow-tine aeration in September is essential for improving drainage and preventing root damage from waterlogged conditions.
