Making bunkers more consistent

Providence, R.I. – Many golf course superintendents throughout the country know that bunker consistency is probably the biggest complaint – legitimate or not – they hear from golfers at their club or course. The number of complaints about bunkers is because superintendents have done such a good job of maintaining greens, tees and fairways, according to Jim Baird, green section agronomist for the U.S. Golf Association. Baird spoke at the New England Regional Turfgrass Conference & Show in Providence, R.I., March 7-10. He suggests superintendents look at five aspects of bunkers to help make them less inconsistent. Those areas are: architecture, construction, sand selection, etiquette and maintenance practices.

Jim Baird, green section agronomist for the USGA, offered tips on bunker care at the New England Regional Turfgrass Conference and Show.

Architecturally, placement, style and grass selection are important. Baird says make sure there are easy entry and exit points for golfers and that no double hazards are created, such as putting a bunker around a tree. Superintendents should decide whether they want a manicured or a natural look. They also should monitor pest control and thoughtfully consider grass selection on south facing slopes because of the constant exposure to the sun.

When bunkers are being shaped, a club’s members and the superintendent should know what’s wanted before they’re shaped. Baird gave an example of one course that had steep bunkers. The members requested the superintendent rake the sand off the face down into the bunkers exposing bunker walls – a look that was undesirable.

Proper drainage also is needed. Superintendents need to make sure water isn’t flowing into the bunkers. Liners made of fabric or sod are other aspects that contribute to bunker consistency.

When selecting sand, Baird says color doesn’t matter, but told attendees to make sure the sand isn’t too white, creating a blinding glare for golfers. Particle size, distribution and the shape of the sand also affect playability. Baird suggests superintendents do their homework and compare various colors and costs of different types of sands before purchasing.

Etiquette also affects bunker consistency. Golfers are expected to exhibit proper etiquette, of which they can be reminded by the superintendent. Baird suggested rakes should be placed outside the bunker and parallel to play.
Maintenance practices affect consistency, too. Wetting agents can help keep sand moist and firm and in some cases can improve drainage. Other practices to be considered are rolling and tamping, checking depth regularly (about twice a year) and hand versus mechanical raking.

In all, Baird asks the question, “Are we spending more money on hazards than other playing surfaces?” It’s something to consider. GCN
