THE EVIDENCE

A repaired pitch mark costs nothing. An unrepaired one costs three weeks.

Golfers who look after the course save their club real money — and it is measurable. Below is the published research on pitch marks and divots, and a model you can run on your own rounds and wage figures to see what the damage is costing in green-staff hours.

Three numbers that matter

  • 24 hrs vs 3 weeks

    Repaired straight away, a pitch mark starts recovering within 24 hours. Left longer than a day in normal growing conditions, recovery takes over three weeks.

    Wrong technique doubles the recovery time and leaves the largest permanent scar. Kansas State found the problem was the golfer's method, not the tool.

On the greens

  • Properly repaired marks recover fully in two to three weeks. Repaired with poor technique, that doubles — and the scar that remains is the largest of any treatment tested.
  • Two days after repair, unrepaired marks measured 640 mm² of scarring on soft greens against 459 mm² on firm ones — soft, receptive greens punish neglect about 39% harder.
  • A busy course takes more than 1,000 ball marks a day. The Belfry's team reports repairing up to 30 on a single green on a bad day.
  • Pitch-mark scarring costs usable hole locations. The Belfry estimates five or six more pin placements per green would be available if the surfaces were undamaged — and fewer placements means wear concentrates, which causes more damage again.
  • Unrepaired marks are an entry point for weed invasion, which is how Poa annua gets into a bentgrass green. That cost arrives later, as herbicide and re-turfing.

On the fairways and tees

  • A filled divot still has to germinate before it recovers — under a week for perennial rye, around two weeks for creeping bent, up to a month for Kentucky blue.
  • On warm-season turf there is effectively no recovery over winter. The USGA's line is that a divot taken in December "might still be there in May" — which for couch fairways here means a divot taken in June is still there in November unless someone fills it.
  • The benchmark GCSAA survey put average annual divot repair at US$3,671 on course tees, US$4,240 on fairways and US$3,383 on range tees — roughly A$28,000 a year in today's money, with courses reporting anywhere from $500 to $33,000.

Where it turns into money

Labour is between 55% and 60% of a course maintenance budget in the GCSAA's 2024 survey, and the USGA now puts it above 70% at many clubs. Nothing else on the budget moves like hours do, so a task that quietly consumes crew time every single morning is the one worth costing out.

The anchor figure comes from The Belfry: mowing the Brabazon's greens takes five hours, and staff spend roughly 15 minutes on each green just repairing pitch marks. Across 18 greens that is four and a half hours a day — before a mower moves. It is the clearest published measurement of what golfers leave behind.

A worked example for a mid-sized Australian club. Every input is adjustable in the calculator below.
Rounds a year 40,000
Pitch marks a round 8
Pitch marks a year 320,000
Crew time at 15 seconds each 1,330 hrs
Greenkeeper cost, fully loaded $47/hr
Value of the whole repair burden $62,700

That total is the ceiling, not the bill — members already repair some of it, and no club gets to zero. But the arithmetic reconciles with the only real-world measurement available: 15 minutes a green across 18 greens, at 15 seconds a mark, is about 1,050 marks a day, which is what roughly 130 rounds at eight marks a round produces. The model and The Belfry's stopwatch agree.

Run it on your own numbers

Change any figure. The defaults are the worked example above; the two behaviour figures are the ones a training programme actually moves.

Competition and social play together.
Approach shots that hold the green. Higher on soft greens.
Crew time per mark, including walking to it.
Fully loaded — wage plus super, leave and on-costs.
Share of marks the members fix properly themselves.
Where a club that teaches the skill can realistically land.
CREW COST TODAY $37,600 800 hours a year
CREW COST AFTER $15,700 333 hours a year
SAVED EVERY YEAR $21,900 467 hours back to mowing, bunkers and presentation

This is an estimate built from published figures, not an audit. It counts pitch marks only — divots, bunkers and the later cost of weed invasion sit on top of it.

Which makes it a training problem

The research keeps landing on the same point: willingness is not the constraint. Kansas State found that poor technique — not the tool, and not indifference — doubled recovery time and left the worst permanent scar. Purdue found a wooden tee scored 5.4 against 5.0 for leaving the mark alone. A club full of well-meaning members using a tee badly is paying most of the cost anyway.

A sign at the first tee assumes the golfer already knows how. That is the assumption the numbers do not support. Green Card teaches pitch-mark repair, divot filling, bunker care and pace as assessed material, and then gives the golfer something that shows they have done it — so a club can tell the difference at the counter rather than hoping.
