Golf Course Masterclass: How the Pros Do It

Ever wondered how golf courses achieve that perfect grass? The kind that looks impossibly green, feels like carpet underfoot, and recovers from thousands of footsteps every week?

I spent over 20 years as a professional greenkeeper, including 8 years at Clandeboye Golf Club working under Terry Crawford. Terry has been a longtime mentor and friend to the Premier Lawns YouTube channel, and he taught me most of what I know about maintaining championship-level turf.

This series took me to Clandeboye, Belvoir Park, Bangor, Donaghadee, and across to Ballyliffin in Ireland. Some videos were filmed over months of visits. The two green build videos alone required dozens of return trips. For the seaweed video, we drove the best part of 1000 miles to tell the story properly.

The Headliners

The best videos in the series start here if you want to understand how the pros achieve perfect grass.

A Masterclass on Cutting Grass Extremely Short

This is the video that kicked off the entire series. I visited Donaghadee Golf Club to meet course manager James Devoy and learn how they cut grass at just 3mm, a height that would destroy most home lawns within days.

The greens at Donaghadee are primarily bentgrass and annual meadowgrass, and maintaining healthy turf at these extreme heights requires precision that goes far beyond owning a good mower. James walks through everything: setting up the cutting units on their Toro triplex mowers, using an Accu-gage to dial in exact heights, and testing cut quality with nothing more than a piece of paper.

If you've ever wondered why your lawn struggles when you cut it short, this video explains exactly what the pros do differently.

How the Pros Carry Out Lawn Maintenance at a Championship Golf Course

This was one of the first videos I filmed at Clandeboye, and it's still one of the most comprehensive looks at autumn renovation you'll find anywhere. Terry Crawford, the course manager, invited me down to the Dufferin championship course to document every step of their autumn greens maintenance.

You'll see verti-draining for deep aeration, grading with a Graden machine for subsurface thatch removal, overseeding with a fescue and bent mixture, and top-dressing with USGA-spec sand. The Graden work is particularly interesting, it's a form of deep scarification brought over from America and Australia specifically to deal with thatch layers that sit below the surface.

Terry explains not just what they're doing, but why each step matters and how it all fits together. This is championship-level maintenance from someone who's been doing it for decades.

The KEY to PERFECT GRASS | How They Do It on a Golf Course

I filmed this at Belvoir Park Golf Club with Aaron Small, and it's one of the clearest explanations of why aeration, scarification, and topdressing are critical to turf health. Aaron breaks down each step of their greens maintenance and explains how these processes keep thatch levels low and promote healthy grass.

One thing worth noting: in this video, they're using solid tine aeration rather than hollow coring. There's a misconception in home lawn care that solid tines aren't effective, that you need to remove cores to get results. That's not true. Solid tines are used on championship golf courses regularly, and Aaron explains when and why they are chosen.

It's a useful reminder that there are multiple ways to aerate effectively.

Why You Should Use This Fertiliser to Get an Amazing Lawn

We drove the best part of 1000 miles across Northern Ireland and Ireland to tell the full story of seaweed as a turf treatment, from harvest to application.

The journey started on the west coast of Ireland at a seaweed factory to see how it's sustainably harvested and processed. From there, we travelled to Ballyliffin Golf Club, home of the 2018 Irish Open, to meet links superintendent Andy Robertson and find out why seaweed is such an important part of his maintenance programme.

Finally, we returned to Belfast to meet Dr Deborah Cox at Belvoir Park Golf Club, who explained the science behind seaweed's effectiveness: root development, stress tolerance, seed germination, and soil health.

This video was made before we launched our own seaweed product through iGrow Carpet. We now sell our own brand, but the science and benefits described here apply to quality seaweed products in general.

The Foundations

Core techniques that professional greenkeepers use to maintain healthy turf: aeration, sand, seed, and renovation.

The KEY to PERFECT Grass Lies Below, How the Pros Do It

If there's one thing that separates professional turf from struggling home lawns, it's what happens beneath the surface. This video focuses entirely on aeration, the different types, when to use each, and why it matters so much for grass health.

You'll see hollow tine, slit tine, and solid tine aeration in action, with clear explanations of what each type achieves. Understanding when to pull cores versus when to simply spike the ground is knowledge that most home lawn owners never get, and it makes a real difference to results.

Why Do They Use Sand on Golf Greens

Back at Clandeboye with Terry Crawford for this one. It's a question I get asked constantly, why do golf courses spread so much sand on their greens? This video answers it properly.

Terry explains the role of sand in greens maintenance, how the Dryject system injects sand deep into the rootzone, and how to determine whether sand is suitable for use on turf. You'll also see how this compares to ordinary top-dressing, and Terry breaks down the differences between verti-cutting, scarification, and grading, three terms that often get confused.

The KEY to a SMOOTH Green, in 3 EASY Steps

This video breaks down green renovation into its simplest form: overseed, achieve good seed-to-soil contact, and top-dress with sand. It sounds straightforward, but watching professionals execute each step shows just how much technique is involved.

You'll see how seed is brushed into the surface, why seed-to-soil contact is so critical for germination, and how sand top-dressing creates the perfect environment for new grass to establish. There's also a useful section on getting seeds to germinate in shaded areas where light is limited.

Why Golf Courses Renovate Greens (and How), It's AMAZING!

I filmed this at Bangor Golf Course with head greenkeeper Alan McKay and deputy Phil. It's a complete walkthrough of a full greens renovation, why courses tear their greens apart every year and how they put them back together.

What makes this video particularly useful is the troubleshooting aspect. Alan and Phil discuss dealing with anthracnose, root damage, and compaction, real problems that they encounter and have to solve. You'll also see the robotic mowers used on the fairways, offering a glimpse into how modern golf course maintenance is evolving.

The Deep Dives

Complete USGA golf green construction from start to finish, both filmed at Clandeboye over several months.

How to Build a Golf Green (USGA) START to FINISH

This is the most popular video in the entire series, and it's easy to see why. We completed the rebuild of an existing green on the Dufferin course at Clandeboye, from removing the old, poorly drained green to the finished putting surface.

The project ran over several months, and I was back and forth to the course throughout. Terry Crawford and his team dealt with everything: lifting the old turf, installing new drainage, laying the rootzone, turfing the new surface, and managing the inevitable disease pressure that comes with new greens. We even visited Irwin's Quality Aggregates to see how USGA-specification sand is manufactured and tested.

Golf course designer David Jones also features, explaining the thinking behind the new green design.

What It REALLY Takes to Build a USGA Golf Green (Start to Finish)

After the first green build video was released, the comments were filled with questions. We created this follow-up to address their questions more comprehensively, providing a deeper look at green construction.

This time, we documented the rebuild of the 10th green on the Ava course at Clandeboye. The old green had drainage issues and rocky ground that made it unplayable, so the club decided to start fresh. Like the first video, this was filmed over months of visits as the work progressed.

If you watched the first green build and wanted more detail on any aspect, the drainage installation, the rootzone preparation, the turfing process, or the challenges of establishment, this video delivers it.

The Extras

For golf fans who want to go deeper: tournament preparation, machinery, construction, and professional event setup.

How the Pros Cut Grass to Perfection | Tournament Prep

Back at Belvoir Park with Aaron Small for this one, filmed during their scratch cup preparation. Aaron invited me down to see how the course was set up for competition, and his team were there well into the night on Saturday, getting everything ready, then back again early Sunday morning.

You'll see exactly how they stripe the grass, what height the greens are cut at, and how they measure and increase greens speed using a stimpmeter. There's also detail on feeding greens before tournaments and on achieving the low cut heights that competition golf demands.

The Machinery Needed for a Golf Course

Part of our series on what it takes to run a modern golf course, this video is a tour of the machinery shed at Belvoir Park. Aaron Small walks through every piece of equipment they use to maintain the course, and there's a lot of it.

From Toro cylinder mowers and the Sidewinder greens unit to John Deere tractors, precision sprayers, and Bernhard grinders, you'll see what professional course maintenance actually requires. It's an eye-opening look at the investment and logistics required to keep a championship course in condition.

What It Takes to Run a Modern-Day Golf Course | Golf Course Construction

This was a solid week's project to film. We documented bunker construction at Belvoir Park, working with Aaron Small and golf course architect William Swan from Swan Golf Design.

William discusses the rationale for bunker placement and how it fits within the overall design of the Sir Henry Cotton course. You'll see the complete construction process from excavation through to the finished bunkers, a side of golf course work that most people never get to witness.

How the Pros Look After Perfect Grass | PGA EuroPro NI Masters

Clandeboye hosted the PGA EuroPro NI Masters, and Terry Crawford invited me down to document how the course was prepared for a professional tour event. This one's a bit different from the others, less about techniques you can apply and more about the scale and precision of tournament preparation.

Terry walks through the complete setup: choosing pin positions, bunker preparation, cutting schedules before and during the event, and keeping greens in peak condition throughout the tournament. We also caught up with local favourite Jonathan Caldwell (it's his home club) and Simon Edwards, the EuroPro Tour Chief Referee, who explains how pin positions are selected.

If you're a golf fan who's ever wondered what goes on behind the scenes at a professional event, this is your answer.

Golf Course Techniques for Your Lawn

Can I apply golf course techniques to my home lawn?

Yes, but with modifications. Golf course greens are maintained to extreme standards that aren't necessary (or sustainable) for home lawns. The principles work the same: regular aeration, controlled thatch, proper mowing height, and consistent feeding. But you don't need championship-level equipment or daily maintenance.

Focus on the fundamentals shown in these videos: annual aeration, light scarifying when needed, proper mowing technique, and seasonal feeding. These practices, applied sensibly, will dramatically improve any domestic lawn.

Why can golf greens be cut so short when my lawn can't?

Golf greens use specialist grass varieties (primarily bentgrass and fescue) bred for low mowing heights. They're maintained with cylinder mowers adjusted to precision tolerances, cut daily or multiple times per day, and supported by intensive aeration, feeding, and disease management programmes.

Domestic lawns typically contain ryegrass and other species that don't tolerate cutting below 20mm. Attempting to achieve golf-green heights on normal lawns weakens the grass, encourages weeds and moss, and eventually kills the turf. Stick to 25-35mm for healthy domestic lawns.

What's the most important technique from golf course maintenance?

Aeration. Hands down. If you could only adopt one practice from professional greenkeeping, it would be regular aeration. Compacted soil is the root cause of most lawn problems: poor drainage, weak growth, moss invasion, and disease susceptibility.

Annual aeration (autumn or spring) has the greatest impact on lawn health of any single intervention. It doesn't require expensive equipment either. A garden fork and an hour's work will dramatically improve most domestic lawns.

Do I need USGA-specification sand for my lawn?

No, USGA sand is designed for golf greens with specific drainage and compaction requirements.

For domestic lawns, good-quality, topdressing sand works well for top-dressing after aeration.

Topdressing sands are typically sub-angular or rounded in shape. This promotes drainage and prevent compaction, which are crucial for if your going to use sand on your lawn.

Avoid builder's sand (too fine, can create compaction) and beach sand (salt content damages grass). Your local garden centre's lawn sand is usually suitable for home use and much more affordable than USGA-spec material.

We only recommend sand, if your lawn is already sandy.

Should I scarify my lawn as they do on golf greens?

Scarify when needed, not on a fixed schedule. Golf greens are scarified regularly because they're cut so low and maintained so intensively that thatch builds up quickly.

Check your lawn's thatch layer by pushing your finger into the turf. If you can feel more than 12mm of spongy material before reaching soil, scarifying would help.

Scarification helps maintain a healthy thatch layer.

If the thatch layer is minimal, scarifying does more harm than good by tearing up healthy grass unnecessarily.
