Discover 10 essential things about golf course maintenance – explained in simple terms, from daily mowing and watering to fixing divots and more.
What You Need to Know About Golf Course Maintenance – 10 Essential Tips and Facts
Have you ever wondered how golf courses stay so green and perfect? It turns out a golf course needs a lot of care and hard work every day. In fact, golf course maintenance is a never-ending job, because a golf course is like a living organism that needs constant attention. From early morning mowing to late afternoon watering, a dedicated team of groundskeepers works behind the scenes to keep the course healthy and enjoyable. This article will walk you through the 10 things you need to know about golf course maintenance. We’ll explain each part in simple terms, so even a 7th grader can understand. By the end, you’ll appreciate the tremendous effort that goes into keeping those fairways and greens in top shape.
A dedicated groundskeeper cleaning a mower at the course’s maintenance facility. Golf course maintenance involves many behind-the-scenes tasks like this. The maintenance facility is like the course’s garage, where all the mowers and tools are stored and serviced daily. Keeping the equipment clean and in good shape is essential for the crew to do their job effectively.
Why Golf Course Maintenance Matters
Golf course maintenance isn’t just about looks – it’s about making sure the course is safe, fair, and fun to play on. Well-maintained turf ensures the golf ball rolls smoothly on the greens and bounces predictably on the fairways. Good maintenance also keeps the grass healthy and strong, which helps prevent weeds and damage. Plus, caring for a golf course protects the club’s big investment in the landscape. Many courses spend hundreds of thousands of dollars each year on upkeep, including things like mowing, watering, sand trap care, and more. In fact, labor (the work the maintenance crew does) makes up about 50–60% of those maintenance costs. Without regular golf course maintenance, a beautiful golf course could quickly turn brown, bumpy, and unplayable.
Tip: Next time you’re on the course, take a moment to notice how smooth the greens are or how neatly the bunkers are raked. That’s all thanks to the golf course maintenance crew’s hard work!
Top 10 Things to Know About Golf Course Maintenance
Let’s explore ten key aspects of golf course maintenance. These are the main tasks and factors that keep a golf course in great condition year-round. We’ll also compare these tasks side by side later on, so you can see how often they’re done and why each is important.
1. Daily Mowing of Greens and Fairways
What it is: Mowing is the most basic (and most important) part of golf course maintenance. The grass on a golf course – especially on the putting greens – is kept very short. Groundskeepers use special mowers to cut the grass almost every day. On greens, the grass might be cut as low as about 0.125 inches (one-eighth of an inch) short! Keeping grass this short and smooth helps golf balls roll true when you putt.
Why it matters: If the grass gets too long or uneven, putts and shots won’t go straight. Daily mowing ensures a fast, smooth putting surface and well-manicured fairways. It also creates those satisfying stripe patterns you see on golf course lawns. Frequent mowing actually makes the turf grow in thicker and healthier over time (similar to how a haircut can make hair seem thicker). By trimming a little bit each day, the crew keeps the grass at the ideal height without stressing it too much.
How it’s done: Greens are usually mowed in the early morning before golfers start playing. Groundskeepers often use lightweight walk-behind mowers or small riding mowers that are specially designed for greens. Fairways and rough (the longer grass areas) are cut a bit higher and may be mowed a few times a week instead of daily. The mowers have very sharp blades to ensure a clean cut. In some cases, greens are also rolled with a heavy roller machine after mowing to make them extra smooth.
Tip: Ever wonder why you sometimes see golf course maintenance workers mowing at sunrise? Golf courses often mow early in the day to avoid disrupting players and to give the grass a fresh cut before play begins.
2. Watering and Irrigation
What it is: Just like any lawn or garden, golf courses need water. Proper golf course maintenance includes careful irrigation planning to give each part of the course the right amount of water. Irrigation is the system of sprinklers and hoses that water the grass. Golf course irrigation is carefully scheduled and controlled so that each part of the course (greens, tees, fairways, etc.) gets the right amount of water. Modern courses often use computer-controlled sprinkler systems that can be set to water during the night or early morning hours.
Why it matters: Grass needs water to stay green and healthy. Too little water and the grass dries out and turns brown; too much water and the grass can drown, or fungus might grow. A good watering plan keeps the turf strong and prevents dry spots on greens that could affect the roll of the ball. Watering is usually done deeply but infrequently – meaning they soak the ground thoroughly, then wait a bit before the next watering. This encourages grass roots to grow deeper, making the turf more resilient.
How it’s done: Many golf courses water early in the morning (often before dawn) or late in the evening. This is because watering during the hot midday sun can waste water (due to evaporation) and can even harm the grass (water droplets in strong sun can scorch leaves). Courses have large underground pipes and sprinkler heads across all areas. It’s a huge job – an average 18-hole golf course (around 150 acres) might use about 200 million gallons of water per year for irrigation. To save water, some courses use recycled or reclaimed waterfluencecorp.com for irrigation, and they carefully monitor weather and soil moisture. During droughts, courses might water less and let the grass grow a bit longer to survive.
Tip: If you see sprinklers running while you play, don’t be surprised – sometimes spot-watering is needed for dry areas even during the day. Just kindly let the groundskeeper finish or wave to them, and they’ll usually pause the sprinkler for you.
3. Fertilizing the Turf (Feeding the Grass)
What it is: Feeding the grass with fertilizer is another key part of golf course maintenance. Fertilizing means adding nutrients to the soil to feed the grass. Over time, grass can use up the natural nutrients in the soil. Golf course crews apply fertilizers (often containing nitrogen, phosphorus, and potassium) to keep the grass green and strong. They might use both granular fertilizers (small pellets spread on the ground) and liquid fertilizers (sprayed on the grass).
Why it matters: Think of fertilizer as vitamins for the grass. With regular feeding, the turf grows dense and rich in color. Without enough nutrients, grass can become thin, pale, or more prone to diseases. On a golf course, healthy grass means better playing conditions – the ball sits up nicely on a well-fertilized fairway, and divots (chunks of grass) recover faster from damage. Fertilized turf also outcompetes weeds, which means fewer weeds on the course. However, fertilizing must be done carefully so as not to pollute waterways or harm the environment. That’s why many courses follow strict guidelines on how much and when to fertilize.
How it’s done: Groundskeepers typically fertilize greens more frequently (because those grasses are cut shortest and need the most care) – sometimes lightly every couple of weeks during the growing season. Fairways and other areas might be fertilized a few times per year or seasonally. They often do this in the early morning or at times when golfers aren’t around, because they might need to drive a spreader machine across the course or spray liquids. Rain or watering after fertilizing helps wash the nutrients into the soil so the grass roots can absorb them.
Tip: Organic fertilizers (like compost or special natural blends) are increasingly popular because they improve soil health in the long run. Some golf courses use organic products to be more eco-friendly while keeping the grass nourished.
4. Aeration (Punching Holes in the Ground)
What it is: Aeration is when the golf course maintenance crew pokes small holes all over the turf. If you’ve ever seen a green or fairway with hundreds of little holes (or plugs of soil pulled out and left on top), that’s aeration. It might look strange, but it’s very important as part of golf course maintenance. Aeration usually involves using a machine that drives many small spikes or hollow tines into the ground.
Why it matters: Over time, the soil under the grass can become compact – meaning it gets packed down from golfers walking and carts driving over it. Compacted soil makes it hard for grass roots to breathe and for water to soak in. Aeration relieves this compaction by creating holes that loosen the soil. These holes allow air, water, and nutrients to reach deeper into the ground and down to the roots. Aeration also helps reduce thatch (a layer of dead grass that can build up on the soil surface). By removing small plugs of dirt, aeration opens up space for new root growth and helps the turf grow stronger. Think of it like loosening the dirt in a potted plant to let it breathe.
How it’s done: Golf courses typically aerate greens once or twice a year (often in spring or fall). They use a special aerator machine that rolls over the turf punching holes. Sometimes they remove the little plugs of soil; other times they break them up and brush them back into the holes. After aeration, they often spread a thin layer of sand on the greens, called topdressing, which fills the holes and helps the greens heal faster. It might take a week or two for the greens to fully recover from aeration – during this time, the surface might be a bit bumpy, but it’s for the long-term good of the course.
Tip: If you arrive at a course and see a notice that “greens were aerated recently,” be prepared for a little slower putting. It’s a necessary inconvenience that keeps the grass healthy. In return, the greens will be in much better shape for the rest of the season.
5. Pest and Weed Control
What it is: Golf course maintenance also involves protecting the grass from pests (like insects or turf diseases) and weeds (unwanted invasive plants). Groundskeepers monitor for signs of pests such as beetles or grubs that can eat grass roots, and for fungal diseases that can create brown patches. They also remove or treat weeds like dandelions or crabgrass that pop up on the course. To do this, they may apply pesticides (insect killers), fungicides (fungus fighters), and herbicides (weed killers) in careful amounts. Many courses also use natural or integrated pest management practices – for example, introducing beneficial insects that eat the harmful ones, or using non-chemical methods when possible.
Why it matters: If left unchecked, a pest infestation or aggressive weeds can ruin large areas of a golf course. For instance, certain beetle larvae can eat the roots of the grass, causing whole patches of turf to die off. Weeds can outgrow grass and create clumpy, ugly spots that affect play. Disease can quickly turn greens or fairways brown. By staying on top of pest and weed control, the maintenance crew ensures the turf stays lush and uniform. This means your ball won’t end up in a random bare patch in the middle of the fairway, and the greens will be consistently green and healthy.
How it’s done: The key here is regular inspection. Groundskeepers often scout the course for signs of problems. If they spot mushrooms or unusual spots on a green, they might treat it with a fungicide early to stop a disease. Many courses apply pre-emergent herbicides (which prevent weeds from sprouting) at certain times of year. They might also set traps for insects or use special soaps on the grass that deter pests. Whenever chemicals are used, the crew does it carefully, usually in the evening or when players aren’t nearby. Many modern golf courses have moved toward using more eco-friendly pest control, to protect local wildlife and waterways.
Tip: Golfers can help in this area too. By cleaning your shoes and equipment between rounds, you can avoid accidentally bringing weed seeds or diseases from one course to another. It’s a small way to assist in keeping the course pest-free.
6. Sand Bunker Maintenance
What it is: Bunkers (sand traps) are the sandy pits you try to avoid when golfing. Maintaining bunkers is another important part of golf course maintenance. This includes raking the sand, checking its depth, and ensuring good drainage. If you’ve ever been in a bunker with water or hard, compacted sand, you know it’s not fun – that’s why bunkers need daily attention too.
Why it matters: Properly maintained bunkers have fluffy, even sand that allows a golfer to hit out of them. If bunkers aren’t raked, the sand can become hard or develop grooves and footprints that ruin the next player’s shot. Good maintenance also ensures the sand level is consistent (usually around 4–6 inches of sand in a bunker) so that you don’t hit the soil underneath. And since bunkers often collect rainwater, they need good drainage; otherwise, they can flood or stay wet for days.
How it’s done: Every morning, golf course maintenance staff typically go around with special bunker rakes (either hand rakes or small machine rakes) to smooth out each sand trap. They rake bunkers to erase footprints and club marks, and to loosen the sand surface. They also trim the grass edges around bunkers and make sure no weeds are growing in the sand. A few times a year, crews may add fresh sand to bunkers or check the drainage pipes underneath. They try to keep the sand at the right level and consistency. After heavy rain, bunkers often wash out (sand slides down the slopes), so the crew will shovel sand back in place and restore the bunker’s shape.
Tip: As a golfer, you can help maintain bunkers by smoothing out your footprints with the provided rake after you play from a sand trap. It’s a courteous habit that keeps the course nicer for everyone. The maintenance team will still do a full rake each day, but every little bit helps!
7. Divot and Ball Mark Repair
What it is: Divots and ball marks are the small damages golfers cause to the course while playing. A divot is a chunk of turf that gets sliced out when a club hits the ground (often on fairways or tee boxes). A ball mark (or pitch mark) is the little dent a ball makes when it lands hard on a green. Part of golf course maintenance is regularly fixing these divots and ball marks so that the grass can heal and the surface stays even.
Why it matters: If divots are left unrepaired, they create bare spots and uneven lies on the fairway. Nobody likes discovering their ball sitting in someone else’s divot hole! Similarly, ball marks that aren’t fixed can kill the grass on a green, leaving pockmarks that can throw off a putt. Repairing these quickly ensures that the course remains smooth and fair for play. It also helps the grass recover faster. Many golf courses even encourage players to help by replacing their divots or using sand/seed mix to fill them, and by fixing their ball marks on the greens with a little tool.
How it’s done: The maintenance crew usually has someone go around to repair divots and ball marks daily or several times a week. For divots on fairways, they might fill the holes with a mix of sand and grass seed, or replace the cut-out piece of turf if it’s intact. On greens, they use a special pronged tool to gently lift and heal each ball mark. Some courses have volunteers or even organized “divot parties” where members help fill divots on a regular basis. Often, if you ride a golf cart, you’ll see a bucket of sand provided – that’s for players to fill their own divots. The maintenance team refills those sand buckets and also makes the rounds to catch any spots players missed.
Tip: Always try to fix your own divots and ball marks if you play golf. It makes a huge difference. A ball mark can be fixed in just 5 seconds and will heal within a day or two, but an unfixed one can take weeks to heal and leave a scar on the green.
8. Managing Tee Boxes and Rough
What it is: Not every area of a golf course gets the same kind of care, but managing the tee boxes and the rough are also important parts of golf course maintenance. Tee boxes are the flat areas where you tee off; they have short grass but not as short as greens. The rough is the taller grass bordering the fairways. Maintaining these involves mowing at the right height, moving tee markers, and sometimes even rotating the areas used for teeing off.
Why it matters: Tee boxes need to be level and firm so golfers can tee off without slipping, and the grass there must withstand a lot of divots from tee shots. By moving the tee markers (those colored blocks that show where to tee up) each day, the crew spreads out the wear and gives the turf time to recover. The rough, on the other hand, is intentionally longer grass, but it still needs care. If rough grass gets too long or thick, it can become unplayable (and nobody wants to spend forever searching for balls in it!). If it’s too short, it defeats the purpose of being a penalty for missing the fairway. So maintaining the rough at a reasonable height is important for game fairness and pace of play.
How it’s done: Tee boxes are mowed frequently, usually a few times a week, and kept around maybe half an inch to an inch tall. The crew will also periodically fill divots on tee boxes with sand and seed, just like on fairways. They change hole locations on greens daily (more on that below in section 10), and likewise they’ll shift tee marker positions daily or as needed. This spreads out the wear on the teeing ground.
As for the rough, it is usually mowed on a schedule – perhaps weekly or biweekly – depending on how fast the grass grows and the course’s desired difficulty. Sometimes certain areas of rough are kept extra thick for championship-level play, but most public courses keep it fairly manageable. Additionally, maintenance might include trimming around trees, paths, and hazard edges in the rough to keep everything tidy.
Tip: Notice the tee markers next time you play – they likely won’t be in the exact same spot day to day. That’s intentional to keep the teeing area from getting worn out in one place. Also, if you’re practicing on a range, try not to always hit from the same spot on the practice tee; help the groundskeepers by using all the space!
9. Equipment Maintenance (Mowers, Carts, and More)
What it is: It’s not just the grass and sand that need maintenance – the equipment used for golf course maintenance also needs regular care. Equipment maintenance refers to keeping all the machines and tools in good working order. This includes the lawn mowers, tractors, aerators, irrigation pumps, golf carts, and even small items like rakes and flagsticks. Golf course maintenance teams often have a mechanic or equipment manager whose job is to sharpen mower blades, change oil in engines, recharge electric cart batteries, and so on.
Why it matters: If the mowers and other machines aren’t well-maintained, they can break down or even damage the course. For instance, a mower with a dull blade will tear the grass instead of cutting it cleanly, which can make the turf turn brown. A broken sprinkler system could leave parts of the course too dry or flooded. Well-kept equipment ensures that all the maintenance tasks can be done properly and on schedule.
It also saves money in the long run, because machines that are serviced regularly last much longergolf.com. Even golf carts, which players use, need regular maintenance – nobody wants a cart dying out on the 9th hole! Regular upkeep includes checking the batteries (in electric carts) and engines (in gas carts) and performing routine check-ups on critical components (for example, cleaning a golf cart’s battery terminals and topping off water in lead-acid batteries to prolong their life).
How it’s done: Many golf courses have a dedicated maintenance facility or depot (basically a workshop/garage on site)commons.wikimedia.org where all the equipment is stored and fixed. Each day, after the mowers come back in from mowing, they might be washed off, and the mechanic will inspect them for any issues. Blades are sharpened on a routine schedule (sharp blades are crucial for healthy grass).
Engines are tuned up, oil and filters changed periodically, and tire pressure on machines is checked to avoid turf damage from heavy equipment. For electric golf carts, the staff charges them up and performs battery maintenance regularly – knowing the difference between various battery types helps in maintaining them properly. (For example, 48V vs 51.2V golf cart batteries have different maintenance needs and lifespans.) In short, there’s a lot of behind-the-scenes mechanical work that keeps the whole operation running smoothly.
Tip: If you own a golf cart or even just a lawn mower at home, taking good care of the battery and engine can dramatically extend its life. Simple routine checks – like those groundskeepers do – go a long way. (You can find golf cart battery maintenance tips on our blog, which can help you keep your cart running longer.)
10. Seasonal Tasks and Course Setup
What it is: Like many activities, golf course maintenance changes with the seasons and involves special tasks at certain times. For instance, in warm regions, some courses overseed the fairways with rye grass in fall so they stay green in winter. In colder climates, courses have to “winterize” – they might cover greens, blow out irrigation lines so they don’t freeze, and prepare the course to endure snow. Come spring, there’s cleanup and often heavy maintenance like aeration or fertilization to wake up the grass. Course setup is another aspect: this includes setting the hole locations (moving the cup on the green to a new spot each day) and arranging tee markers, as well as putting out things like flags, ball washers, and bunker rakes for players.
Why it matters: Seasonal work ensures the course survives weather changes and is ready for play. If a course didn’t prepare for winter, frost could kill the greens or burst the water pipes. Changing hole positions and tee positions daily prevents any single area from getting overly worn out. It also gives golfers a fresh challenge each day. For example, a hole might be cut on the left side of the green one day and on the right side the next. This not only spreads wear on the green but also keeps the game interesting. Additionally, maintenance crews sometimes plan major projects in the off-season or when the course is closed (like renovating a green or improving drainage) – timing these tasks is key to minimizing disruption during the busy season.
How it’s done: The course superintendent (the person in charge of maintenance) usually creates an annual plan. In the fall, they might plant cool-season grass seed if needed, adjust mowing heights as growth slows, and apply a heavy fertilization before winter (so the grass has nutrients while it’s dormant). They may also schedule tree trimming or other landscaping work in the off-season. In winter, courses may close or have a smaller crew just checking on things occasionally. In spring, they remove any protective covers, repair any winter damage (for instance, treating turf disease that can occur under snow), and get the course ready for the busy season. Hole locations on the greens are changed using a special tool to cut a new hole and insert the cup; this is done daily or every few days. The old hole is filled with a turf plug so it heals up. Tee markers are moved as mentioned in section 8. Throughout the year, the crew also marks hazards, paints stakes (like the red and white hazard markers), and ensures signs and paths are in good shape.
Tip: Weather is a big factor. After heavy rain, the course may restrict golf carts to protect the turf. If you see a “Cart Path Only” sign, it’s because the maintenance team is trying to prevent ruts in soggy ground. Following these rules helps the golf course maintenance crew keep the course in top shape.
Side-by-Side Comparison of Key Maintenance Tasks
Below is a quick comparison of these ten golf course maintenance tasks, looking at how often they’re done and why they are important. This summary shows at a glance the variety of work that goes into golf course upkeep:
| Maintenance Task | How Often? | Main Purpose |
|---|---|---|
| Mowing (Greens & Fairways) | Greens daily; fairways ~3 times/week | Keeps grass short for smooth putting and consistent fairways. |
| Watering/Irrigation | Daily (usually early morning) as needed | Provides water for healthy, green turf; prevents dry spots. |
| Fertilizing | Greens biweekly; fairways/rough a few times per season | Feeds nutrients to grass for growth, color, and strength. |
| Aeration | 1–2 times per year | Relieves soil compaction; helps water/air reach roots. |
| Pest & Weed Control | Continuous monitoring; treatments seasonally as needed | Protects turf from insect damage, diseases, and invasive weeds. |
| Bunker Raking | Daily (each morning) | Smooths sand for consistent play; maintains proper sand depth. |
| Divot & Ball Mark Repair | Daily to weekly (ongoing) | Fixes player damage; keeps turf even and helps grass heal quickly. |
| Tee Box & Rough Mowing | Tees ~2–3 times/week; rough ~1 time/week (varies) | Maintains proper grass height on tees and rough for fair play. |
| Equipment Maintenance | Daily cleaning; service monthly or as scheduled | Keeps mowers, carts, etc. running well; prevents breakdowns that could harm turf. |
| Seasonal Prep & Setup | Seasonally (spring/fall prep); hole locations daily | Adapts course to weather; rotates wear areas for longevity and variety in play. |
As you can see, some tasks like mowing, watering, and bunker raking are done every day, whereas others like aeration are special tasks only done occasionally. All together, these activities ensure the golf course stays healthy and that golfers have a good experience on the course.
