DISEASE WATCH: Key Indicators & Causes
Ascochyta Leaf Blight: Monitor for rapid, widespread bleaching of grass, typically occurring after hot, humid weather followed by a dry spell.
The "Why": Leaf blight is often spread through mowing, particularly when dull blades are used, causing the grass to tear instead of receiving a clean cut. Furthermore, mowing during peak heat increases plant stress, significantly increasing susceptibility to infection. Please ensure your mower blades are sharpened!
Additional Diseases: Be aware of Leaf Spot (dark lesions), Rust (powdery orange spores), and Dollar Spot (small circular bleached patches). These thrive in high humidity, excess thatch, and poor air circulation.
PEST SCOUTING
Sod Webworms: Identify small, tan adult moths flying erratically at dusk. Their larvae cause irregular brown patches by tunneling into the thatch and chewing grass blades.
Japanese Beetles: These metallic green/bronze beetles feed in clusters, skeletonizing leaves on roses, shrubs, and ornamental plants.
SUMMER BEST PRACTICES
Mow Strategically: Maintain your mower deck at 3–4 inches to shade roots and retain soil moisture. Avoid mowing during peak heat and ensure your blades are sharp to prevent disease spread.
Water Effectively: Water deeply and infrequently, ideally in the early morning (4:00 AM – 8:00 AM). Avoid nighttime watering, as wet grass blades invite fungal disease.
LOOKING AHEAD
Our Round 3 applications will commence next week, featuring slow-release fertilizer for steady lawn nourishment through the summer, along with spot-spraying for w**ds and post-emergent crabgrass control as needed.
