Abstract Fraise mowing and hollow‐tine aerification are disruptive cultural practices that alter soil physical properties. The objective of this study was to evaluate the effects of fraise mowing followed by hollow‐tine aerification on soil physical properties in a Cecil sandy loam (loam) and a sand‐capped soccer field (sand) beneath established ‘Tifway’ hybrid bermudagrass ( C. dactylon x C. transvaalensis Burtt. Davy). Three fraise mowing depths (0.25, 0.5, and 1.0 inches) and hollow‐tine aerification were applied in mid‐June in two consecutive years. Turfgrass quality (TQ), thatch‐mat depth, surface hardness, and divot resistance were measured in both soils. Saturated hydraulic conductivity (Ksat) was measured in the sand. All fraise mowing and hollow‐tine aerification treatments resulted in unacceptable TQ for 2 to 6 weeks during the study. However, combining hollow‐tine aerification with fraise mowing did not delay bermudagrass recovery. Thatch‐mat depth decreased by ≥19% as fraise mowing depth increased but was unaffected by hollow‐tine aerification. Fraise mowing did not affect Ksat; however, hollow‐tine aerification increased Ksat by 54%. Surface hardness increased by ≤24% with increasing fraise mowing depths. Fraise mowing did not affect divot resistance in the loam. Divot resistance in sand decreased by 16 and 30% with the 0.5‐ and 1.0‐inch fraise mowing depths, respectively. Hollow‐tine aerification decreased surface hardness by 5% to 20% and divot resistance by 6% to 13%. When practiced concurrently, fraise mowing and hollow‐tine aerification were complimentary and positively affected the soil physical properties in both soils.
