Why Ignoring Lawn Disease Costs More Than You Think
Brown spots, thinning patches, and strange fungal growth aren’t just cosmetic issues. When left untreated, lawn diseases weaken your grass at the root level, allowing pests and weeds to take over. Seasonal stress, overwatering, or compacted soil can trigger serious turf problems that require expensive restoration or even complete lawn replacement. Early detection and treatment save money and preserve your curb appeal.

- Risk Factors: Overwatering, excessive thatch, compacted soil
- Treatment: Core aeration, improved drainage, balanced fertilization, especially sulfur-based formulas
Snow Mold (Gray and Pink)
- Cause: Fungal; Typhula (gray) and Microdochium (pink)
- Season: Early spring as snow melts
- Symptoms: Matted, crusty white or pink patches that smother turf
- Risk Factors: Heavy snow cover on unfrozen soil, excess nitrogen in late fall
- Treatment: Rake out matted areas, apply fungicide if necessary, reduce fall nitrogen use
Summer Patch
- Cause: Fungal (Magnaporthe poae)
- Season: Peak heat of midsummer (JuneāAugust)
- Symptoms: Yellowing patches that turn brown, often with rotted roots beneath
- Risk Factors: Poor drainage, drought stress, compacted soil
- Treatment: Core aeration, improve watering practices, use sulfur-based fertilizers to enhance resistance
Rust
- Cause: Fungal (Puccinia species)
- Season: Late summer into fall
- Symptoms: Fine orange or reddish dust on shoes or mower blades, turf appears faded or dull
- Risk Factors: Shaded areas, low nitrogen, slow-growing grass
- Treatment: Increase nitrogen, mow regularly, improve sunlight and airflow across lawn
Leaf Spot & Melting Out
- Cause: Fungal (Drechslera and Bipolaris)
- Season: Spring and fall
- Symptoms: Brown to purple spots on blades, progressing to full turf dieback (melting out)
- Risk Factors: Overwatering, mowing too short, humid conditions
- Treatment: Raise mower height, reduce watering, and apply fungicides as needed
Dollar Spot
- Cause: Fungal (Sclerotinia homoeocarpa)
- Season: Spring through fall
- Symptoms: Tan, silver-dollar-sized patches with reddish-brown borders
- Risk Factors: Low nitrogen, high humidity, consistent dew
- Treatment: Fertilize properly, improve drainage, and mow at a consistent height

Prevention & Management Tips for Utah Lawns
- Core Aeration (Spring and Fall): Reduces soil compaction and thatch buildup, improving root strength
- Sulfur-Based Fertilization: Builds long-term soil health and disease resistance compared to UREA-based products
- Deep Watering Practices: Less frequent, deeper watering encourages resilient root systems
- Fall Fertilizer Timing: Avoid heavy nitrogen applications before snowfall to reduce snow mold
- Summer Monitoring: Educate property owners on signs of drought stress and when to call for help
- Pest Barriers: Reducing insect pressure (like grubs and chinch bugs) lowers disease susceptibility
