Do this week

  1. Water deep on assigned days only—check drought stage before adding minutes.
  2. Mow higher with sharp blades; avoid midday traffic on heat-stressed turf.
  3. Skip fertilizer and most herbicides until stress eases.
  4. Audit irrigation for runoff, misting, and dry spots after each cycle.

Watch for

  • Tip burn from salts or recycled water
  • Localized dry spot / hydrophobic thatch circles
  • Grubs or billbugs under irregular wilt
  • Monsoon-related fungal flare where nights stay humid

Without a reliable leach rain, soluble salts and specific ions concentrate in the top inch.

Seasonal notes

  • Flush salts only when your water rules allow and turf can use the water.
  • Coastal vs inland microclimates differ sharply—follow your district first.
  • Probe soil before skipping or adding irrigation as SE Texas and western Gulf yards track humid Gulf air through Saturday–Sunday (Houston-class ~90 Friday / ~88 Saturday / ~90 Sunday with Heat Advisories expired this midday; Shreveport-class ~92/~87/~93 with Heat Advisories expired this midday; Lake Charles-class ~90/~85/~91 with Heat Advisories expired this midday; New Orleans-class ~78 Friday / ~74 Saturday / ~86 Sunday with Heat Advisories expired this midday).
