Early August · Rainy-season peak Elevated

Florida lawn conditions

Updated

Let rainfall count; southern chinch bug peak continues on sunny St. Augustine—float-count before spraying; scout leaf diseases; hold heavy nitrogen in sticky humid stretches. Miami-class Saturday ~88 with storm chances (~7%) / Sunday ~88 storms (~12%) / Monday ~89 storms (~12%); Tampa-class Saturday ~90 with storm chances (~25%) / Sunday ~93 storms (~27%) / Monday ~97 storms (~24%).

Do this week

  1. Mow to UF/IFAS species heights with sharp blades; never remove more than about one-third.
  2. Skip irrigation after soaking storms—water only on wilt that soil probes confirm.
  3. Hold heavy nitrogen during prolonged humid, rainy stretches that favor fungus and thatch that shelters chinch bugs.
  4. Scout sunny St. Augustine edges for southern chinch bugs weekly—UF/IFAS ~20–25/ft² treat theme after flotation.

Watch for

  • Southern chinch bugs (irregular yellowing that water does not fix)—midsummer generations overlap
  • Gray leaf spot oblong lesions vs take-all soft black roots vs heat-dome drought on St. Augustine—lens + dig before a jug
  • Take-all / fungal decline with shallow frequent water
  • Sod webworms and armyworms near lights
Regional notes & context

Why this week

Early-August Florida lawns are fighting heat plus humidity. UF/IFAS notes many St. Augustine lawns harbor low chinch numbers—treat only at abundance threshold after you float-count at the damage margin. Extra irrigation on top of Saturday–Monday storm chances and soft nitrogen often invite disease and thatch more than color.

Seasonal notes

  • Raise height slightly if turf is stressed by heat or saturated soils.
  • Bag drainage and low spots that stay soggy after storms.
  • Keep thatch in check during active growth—not as a panic mid-disease scalp.
