Good Etiquette, Great Greens: Why Bother Fixing Ball Marks?
You've probably heard a grumpy-sounding old-timer mutter about fixing ball marks, but this isn't just about appearances. It's about the fundamental health of the putting surface. A deep ball mark is a wound on the green. When a golf ball lands, it forcefully crushes the grass and soil, leaving an indentation and tearing the grass roots.
Here's the breakdown of why a quick repair is so important:
Healing Time: A properly repaired ball mark can recover almost completely in 24 to 48 hours. The roots are still intact, and the grass is simply pushed back into place to continue growing. An unrepaired or improperly "fixed" mark can take two to three weeks to heal. During that time, the exposed soil creates an ugly brown spot, and the bruised grass can die off completely.
A Smooth Roll for Everyone: That little depression doesn't just look bad, it directly affects play. An unrepaired ball mark creates a bump or a hollow that can easily knock a well-struck putt offline. By fixing your mark, you're not just being a good steward of the course, you're being a good fellow-golfer to every group that plays behind you.
Preventing Weed Invasion: A bare patch of soil from a dead ball mark is an open invitation for invasive grass species (like Poa annua) and other weeds to take root. These invaders can compromise the consistency of the entire putting surface over time.
Think of it this way: for every properly fixed ball mark, you are actively helping the grounds crew maintain the course and making the putting experience better for everyone, including yourself, on your next round.

Just like you wouldn't use a driver in a greenside bunker, you need the right tool to repair a ball mark effectively. While just about anything pointy can be used in a pinch, there's a clear hierarchy of what works best.
The Best: A Classic Two-Pronged Divot Tool
This is the gold standard for a reason. The traditional two-pronged divot tool gives you the perfect leverage to work the turf from the sides of the mark without damaging the roots underneath. The prongs are typically thin enough to penetrate the soil easily but strong enough not to bend. Many modern tools also come with a flat, circular top, designed to act as a rest for your thumb for better leverage, and a magnetic ball marker, which is a nice bonus.
The Contender: The Single-Prong Tool
Popularized by brands like PitchFix, the single-prong tool works on a "twist" and "push" logic. You insert the single, sturdier prong into the raised wall of the mark and gently twist it to loosen the compacted turf, then push inward. It's highly effective and a favorite of many good players and superintendents. It prevents the common mistake of prying upwards, as the tool's design doesn't really allow for it.
The Last Resort: A Golf Tee
If you're caught on the green and realize your divot tool is back in your bag, a golf tee will work - but you have to be careful. The sharp, pointed end can easily tear grass if you aren't gentle. However, used with the correct technique, it's far, far better than doing nothing at all. Just make sure to use a wooden or bamboo tee, as plastic tees are more likely to snap.
What shouldn't you use? Avoid using keys, pocket knives, or other sharp, wide objects. These are more likely to tear the sensitive roots beneath the surface, doing more harm than good.
The Step-by-Step Guide to a Perfect Ball Mark Repair
This is it - the simple, effective method that greenkeepers wish every golfer knew. The key concept to remember is that you are pushing the turf around the mark back towards the center. You are never lifting up from the bottom.
Step 1: Get the Right Angle
Identify the crater left by your ball. You'll notice that the turf is pressed down in the middle but raised up around the edges, especially at the "back" of the mark where the ball entered. This raised turf is your target.
Step 2: Insert the Tool
Take your divot tool and insert the prongs into the raised collar of turf around the indentation. Insert it at a slight angle, about 45 degrees, aiming away from the center of the mark.
Step 3: The Motion: Push Forward, Don't Lift Up!
This is the most important part of the entire process. With the prongs in the turf, gently push the tool's handle forward, toward the center of the ball mark. This action pushes the grass and topsoil back into the void left by the ball. Think of it like a surgeon closing a wound or affectionately tucking the grass back in. You are moving from the high ground to the low ground.
What to Avoid: The most destructive thing you can do is stick the tool in and pry upwards. This rips the roots of the grass from deep in the soil, bringing dirt and root matter to the surface. It kills the grass and makes it impossible for the mark to heal quickly.
Step 4: Work Your Way Around the Clock
After your first push, pull the tool out, move it to a different spot around the "clock face" of the mark, and repeat the gentle, forward-pushing motion. Continue this process three or four times, working all the surrounding turf back towards the center until the depression is filled in and the surface is relatively level.
Step 5: Tamp it Down
Your work isn't done yet. After you've pushed the turf back together, the spot will be soft and a bit puffy. To finish the repair, take the bottom of your putter head and gently tamp down on the repaired area. Two or three light taps will smooth out the surface, making it firm and true for putting. You can also use the sole of your shoe, but a putter gives you more precise control.
The result should be a spot that is barely noticeable and completely smooth. You've successfully performed green first-aid!

Knowing what not to do is just as valuable as knowing the right technique. Here are the most frequent errors golfers make when trying to fix a ball mark.
The "Pry and Lift" Blunder: We've covered it, but it bears repeating. Lifting soil and roots from underneath the mark is the number one sin of green repair. It's like trying to fix a cut by pulling it apart. Always, always push inward from the sides.
Just Stomping on It: Seeing a ball mark and simply stomping on it with your shoe doesn't work. All this does is compact the soil beneath the surface, which suffocates the roots and makes it even harder for the grass to recover and for water to penetrate the soil.
Twisting and Gouging: Be gentle. Don't violently twist or gouge with the repair tool. This only tears the turf. The correct motion is a smooth, gentle push.
The "Not My Mark" Mentality: The unofficial rule of good golf etiquette is to fix your own ball mark… and one other. If you see an older, unrepaired mark on the green while waiting to putt, take ten seconds to fix it. This collective responsibility is what keeps premier courses in such great condition. Leave every green better than you found it.
