MM50 Helping Tees Stand the Test of Time: At Southerndown Golf Club in the Vale of Glamorgan, MM50 grass seed has become an essential product. With tees that endure relentless wear from players and exposure to some of the UK’s harshest growing conditions, Course Manager Andrew Mannion has come to rely on the hard-wearing ryegrass mix to keep surfaces strong, consistent, and fit for year-round play.

MM50 is one of the UK’s most popular grass seed mixtures – and with good reason. The blend of fine-leaved, high shoot density dwarf perennial ryegrasses is built for performance: it tolerates close mowing down to 4-5mm, recovers rapidly from wear, and maintains excellent year-round colour. For Andrew, it’s a perfect match for a course that refuses to follow convention.

“Southerndown’s unique,” says Andrew, who’s been at the club for over 30 years. “It’s like managing two courses in one. The front nine is very sandy and free-draining, almost links-like. The back nine is more loamy, heathland terrain. It means you’ve got to think differently about how you manage each area – and what you grow.”

The course sits around 70 metres above sea level on exposed, windswept land. Underfoot, a layer of acidic sand overlays limestone – an unusual soil profile shared by just a few sites in the UK. “That limestone layer can be two metres down, or just a couple of inches below the surface. It creates real challenges when it comes to aeration and water movement. We’ve got good irrigation, but water doesn’t hang around for long.”

Add in grazing rights – Southerndown is built on common land and home to up to 600 sheep, depending on the season – and it’s easy to see why traditional turf practices don’t always deliver.

For many years, Andrew stuck with a fescue-based programme passed down from his predecessor. But in areas of heavy traffic, especially on par-threes, the turf simply couldn’t keep up. “They’d turn to dust in the summer,” he says. “The recovery wasn’t quick enough. We weren’t getting the results we needed, and we were doing the same things every year expecting a different outcome.”

The spark for change came from an unlikely place: Wimbledon. “I remember watching coverage of Centre Court, and they mentioned these new dwarf ryegrass varieties. I thought, well, that’s just a big golf tee really. So, we trialled some MM50 on the worst par-threes – and the difference was incredible.”

The trial showed immediate improvements. “It gave us better grass coverage, but more than that, the recovery from divots was two or three times quicker than anything we’d seen with fescues. In some cases, you’d get shallow divots regenerating naturally without any intervention.”

That initial success quickly led to a full overseeding programme. “We moved to using MM50 across all the tees. It was an easy sell to the club – we could literally say, ‘Look at the par-threes. Why wouldn’t we want all the tees to look like that?’”

The benefits went beyond performance. “Golfers weren’t questioning it. The ryegrass is so fine-leaved that they didn’t even realise it was rye. They just saw a tight, clean surface that looked good and played well.”

MM50 has even made its way onto selected fairways – especially those that suffered during the prolonged heat and drought of 2018. “That year really opened our eyes,” Andrew recalls.

“We always thought fescue would bounce back after going dormant, but it didn’t. It just disappeared. We were dragging hoses out onto bare fairways, trying to save them. That’s when we looked at what we’d achieved with MM50 on the tees and thought – why not try it here too?”

“We’ve got a busy course. It’s used 365 days a year. Members expect value for money. You can’t keep relying on a surface that can’t keep up. MM50 gave us a way forward.”

For Andrew, MM50 hasn’t just improved playing surfaces – it’s changed his outlook. “I’m not one of those who hides behind tradition for tradition’s sake. We tried the fescue route. It worked up to a point, but it wasn’t giving us what we needed. MM50 has helped us manage trickier areas, maintain better grass cover, and deliver a better experience for the golfer.”
