Ball mark Recovery: Does the Repair Tool Matter?

Putting green surface smoothness and uniformity is often disrupted by unrepaired ballmarks. These marks can disrupt surface smoothness and increase the potential for weed (e.g. annual bluegrass) encroachment. The traditional method for repairing ballmarks normally employs a metal pronged tool (≈ 1 in or 3 cm), or tee and using a knit and twist method attempting to pull healthy turf from the perimeter into the ball mark (Figure 1). Recently, several new repair tools, such as the GreenFix Wizard (Figure 2), have been introduced with the intent of improving ball mark repair. Many of these tools utilize a simple pushing method and shorter tong lengths (≈ 1/2 in or 1 cm), with less potential for root disruption. The objective of our field-study was to evaluate golf ball mark recovery of two creeping bentgrass areas with contrasting surface firmness and rootzone moisture contents as affected by various ball mark repair tools. Two adjacent locations were prepared to create “firm” (20% moisture, 0-2 in) and “soft” (28% moisture, 0-2 in) study areas. Four ball mark repair tools (Traditional long-tong tool, angled long-tong tool, GreenFix Wizard, standard length wooden golf tee) plus an unrepaired ball mark were evaluated for visual appearance and ball mark recovery for several weeks after ballmarks were naturally created (Figure 2)
