Why new sod fails from watering mistakes
New sod has shallow roots at first. It needs frequent moisture without staying swampy. The goal is root contact: damp soil below the sod layer, no curled edges, and no puddles that invite disease or wash out grading.
Check coverage before blaming the sod
Dry corners and brown seams are often sprinkler coverage problems. Run every zone and look for blocked heads, short spray patterns, low pressure, and runoff.
Assumptions, units and limits (contractor reviewed)
Run times are minutes per zone, not per head. New sod (0 to 30 days) wants short frequent cycles; established lawns want deep infrequent watering under local rules. Sandy soil drains fast, compacted soil runs off, and rainy-season plans assume cycles are skipped after real rain. Hose and mixed-coverage yards need hand-watering backup.
