If you've spent any time watching golf, you've likely seen a player step onto the putting green, pull a tee from their pocket, and start meticulously poking at the turf. It's a common sight, from the PGA Tour to your local Saturday morning foursome. This small, almost ritualistic action isn't just a nervous habit, it's a critical part of a golfer's routine that combines course maintenance, information gathering, and proper etiquette. This guide will walk you through exactly what golfers are doing when they poke the green and why it’s a habit you should probably adopt, too.

What Are They Actually Doing? It Starts with Repairing the Green
The most common and important reason a golfer pokes the green is to repair a ball mark, also known as a pitch mark. When your ball flies high and lands on the soft surface of a putting green, it creates a small indentation or crater in the turf. Think of it as a tiny landing zone that compresses the soil and displaces the grass.
Leaving this mark unrepaired is a major breach of golf etiquette, and for good reasons. First, an unrepaired mark creates an uneven surface that can deflect a perfectly good putt off its line. There's nothing more frustrating than having your putt knocked offline by someone else's carelessness. Second, and more importantly, it causes long-term damage to the health of the green. The turf roots in a fresh ball mark are bruised and torn. If repaired correctly within a few minutes, the grass can recover completely in about 24 hours. If left unattended, that small patch of grass can die, leaving a brown, barren spot that can take weeks to heal.
One of the first rules every new golfer should learn is to always repair your ball mark, and if you have time, fix one more you see. It’s a simple act of respect for the course and for the players coming after you.
Why a Tee? And Is It the Best Tool?
Golfers often use a tee for this task simply because it’s convenient. You just pulled it from your pocket after your tee shot, and it’s right there, ready to use. It’s thin, pointed, and gets the job done in a pinch. However, a tee is not the ideal tool for the job. Because of its shape, a tee can easily tear the delicate grass roots if not used with care, potentially causing more harm than good.
The best tool is a dedicated divot repair tool. These are specially designed forks with two prongs that are perfectly shaped for lifting and pushing the turf together without damaging the roots underneath. They are inexpensive and a worthwhile investment for any serious golfer. That said, using a tee correctly is far better than doing nothing at all.
The Right Way to Fix a Ball Mark (with a Tee or Divot Tool)
Knowing how to repair a mark is just as important as remembering to do it. The common mistake is to insert the tool and lift straight up, like a lever. This only pulls the roots up to the surface where they will dry out and die. The correct method knits the turf back together.
Insert the tool: Take your tee or divot tool and insert the prongs into the turf on the high side or edge of the ball mark. Do not insert it into the center of the depression.
Push inwards: Gently push the tool forward, toward the center of the ball mark. You are using the tool to push the surrounding grass together to fill the void. Think of it like closing a drawstring bag.
Work your way around: Repeat this inward motion from three or four different points around the edge of the mark until the depression is closed and level.
Tamp it down: Once you've pushed the turf back together, gently tap the repaired area with the bottom of your putter. This smooths out the surface and helps the roots resettle.
When you're done, the mark should be almost invisible, and you've left the green in perfect shape for the next group.

Gathering Intel: Testing the Green's Firmness and Speed
While repair is the primary function, there's another, more subtle reason golfers poke the green. They are gathering last-minute intel about the putting surface. A quick, gentle press of a tee (or even a knuckle) into the turf can tell you a lot about the green's condition.
What you're feeling for is the green’s firmness. This has a direct impact on both your approach shots and your putts:
Soft Greens: If the tee sinks in easily with little resistance, the green is soft. This usually means it's holding more water. For putting, this translates to slower speeds. You'll need to hit your putts with more pace to get them to the hole. When hitting approach shots into a soft green, you can expect the ball to stop quickly, perhaps even spin back, with very little roll.
Firm Greens: If you press the tee and feel immediate, unyielding resistance, the green is firm and fast. This is typical of dry or summer conditions. Putts will roll out much farther, requiring a more delicate touch. Approach shots will take a significant bounce forward and roll out a considerable distance upon landing.
This physical feedback helps a golfer calibrate their feel for speed. You’ve already gotten a sense of the firmness from walking on the green, but this final test right near your ball can confirm your assumptions before you commit to the stroke. It’s a tiny piece of the green-reading puzzle, alongside reading the break, the grain, and the slope, that helps you build a complete picture of the putt.

When Poking Becomes a Penalty: Understanding the Rules
This is where things can get a little tricky. Can this poking and prodding ever get you into trouble? The answer is yes, sometimes. The good news is, the rules of golf were updated in 2019 to be much more lenient on this front. According to Rule 13.1c, a player is allowed to repair nearly any damage on the putting green.
This includes:
Ball marks (pitch marks)
Shoe damage (spike or cleat marks)
Scrapes or indentations from equipment or the flagstick
Animal tracks
Old hole plugs that have settled unevenly
So, if you’re using your tee to fix a spike mark on your line or to tamp down a bumpy old hole placement, you are perfectly within your rights. There is no penalty.
However, the rule still prohibits deliberately testing the surface of the green by rubbing it or scraping it. The line is really drawn at your intent. A gentle press with a tee to gauge firmness is a universally accepted part of the pre-shot routine and falls under the category of “gathering information” rather than “testing.” Scraping the ground with your tee to see how the grass reacts, or deliberately creating a test indentation, would be a violation that carries a penalty.
The general principle is: you can fix existing imperfections, but you cannot improve your line by creating new ones or "testing" the surface in a destructive way.

Building on the rules, you will often see expert players looking for more than just their own pitch mark. Their eyes are scanning their putting line for any subtle imperfection. An old, badly repaired ball mark right on their line? They will gently use their divot tool or the tip of their putter to press it down. A raised edge from an old hole plug? They will tap it flat.
This methodical practice ensures they are giving their ball the smoothest, truest path to the hole possible. By using a tee or putter head to smooth down these minor blemishes, they aren't just performing good maintenance - they're actively managing their environment to eliminate variables that could lead to a missed putt. This is the mark of a thoughtful player who understands that success in golf often comes down to controlling the small details.
Final Thoughts
So, the next time you see a golfer poking the green with a tee, you'll know they're not just fidgeting. They are actively engaging with the course - fulfilling their duty to repair damage, gathering tactile feedback about green speed and firmness, and tidying their line to give themselves the best chance of success. It's a small action that speaks volumes about a player's knowledge and respect for the game.
Understanding the subtleties of green reading and etiquette is a huge part of shooting lower scores and enjoying the game more. Sometimes, especially in a tough spot or on a tricky green, you might wish you had an expert opinion. That's precisely why we built Caddie AI.
