Avoid spring lawn mistakes
Lawn pros warn many summer brown patches start with early-spring errors — mowing too short or over-fertilizing being common culprits — and recommend repairing bald spots now with seed or turf ( ).
Cool-season lawns usually take up fertilizer and seed best once soil temperatures reach about 50–55°F, while warm-season turf generally needs soil near 65°F before feeding or planting. (lawnlove.com) Perennial ryegrass typically germinates in about 7–14 days, tall fescue in roughly 10–20 days, and Kentucky bluegrass can take 14–28 days to sprout, with full stand recovery often requiring several weeks to a full growing season depending on mix. (jonathangreen.com) Sodding gives instant coverage and usually establishes within 2–3 weeks, while seeding costs far less but needs 7–21 days to germinate and commonly 6–8 weeks or more for substantial turf cover; sod can run roughly 5–8 times the per‑square‑foot cost of seed. (angi.com) Core aeration before overseeding is broadly recommended because removing soil cores improves seed‑to‑soil contact and increases water and nutrient penetration; university extension guides advise renting a core aerator for large renovations. (extension.umd.edu) Newly sown seed should have the top 1/2"–1" of soil kept consistently moist, typically by light watering 1–3 times per day for the first 7–14 days, then reducing frequency and increasing depth as roots develop. (lawninsiders.com) Brown patch is a summer foliar disease caused by the fungus Rhizoctonia solani that produces circular brown rings on cool‑season turf and becomes most active under hot, humid summer conditions.
