Sustaining a golf course will be robust in any context. However attempt tending turf within the hottest, driest spot in North America, on the lowest-elevation format on the earth.
Bobby Alford is the assistant superintendent at Furnace Creek Golf Course, in Demise Valley, Calif., the place the property bottoms out at 214 ft beneath sea degree and summertime temperatures routinely crack 120 levels.
We requested him how these searing situations have an effect on course maintenance, and the way he and his crew handle to maintain their cool. To listen to extra from Alford, try the video accompanying this text.
What to learn about H20
Furnace Creek is a literal oasis. It sits on historic springs that offer what Alford describes as “just about limitless water.” Not that he’d ever need to waste it, which suggests the sprinkler heads go off when the solar is up. In a variety of locations, irrigating turf at evening is taken into account a no-no, as moist situations, left to linger, invite illness and different issues. It’s a distinct story at Furnace Creek, the place most irrigation occurs after darkish: 8 p.m. to five a.m. is prime time to water, Alford says. “It’s simply not a difficulty for us as a result of the water doesn’t stick round for lengthy.” Typically, he and his workforce spot-water in the course of the day. “However to water within the day you nearly must water twice as lengthy for it to do its job.”
Which turf can take it?
Spoiler alert: not a cool-season grass. Alford and his workforce have tried a bunch of turf varietals. At instances, he says, he feels they’ve been bought a invoice of products. “Lots of the grasses that firms have prompt we use, all of them sprout good,” Alford says. “However then about two weeks later, they begin to die.” Nothing they’ve tried tops the 2 strains they’ve come to depend on: widespread Bermuda on the tees, fairways and within the tough, and Tifway 419 Bermuda on the greens. “We’ll have instances when the bottom temperature at evening is 101 levels, and the grass by no means has an opportunity to chill off. Bermuda is the one one that may stand it.”

Mellower mowing patterns
Mowing is diminished from every single day to each different day, which minimizes put on and tear in a anxious season. It additionally provides time for the grass to develop, a key to turf resilience. The longer and lusher the leaf blades, Alford says, the higher the grass can endure the warmth.
Human limitations
To guard its friends, Furnace Creek restricts tee instances in the summertime. If you wish to play 18, you must begin earlier than mid-morning. The course takes comparable precautions with its workers, bumping shifts earlier within the morning (they begin at 4 a.m. as an alternative of 5:30 a.m) and reducing off the work day at midday. Common breaks are inspired, and if the temperatures close to 120 levels, outside work is named off and everyone seems to be introduced inside.
Machine vs. nature
Excessive warmth will be exhausting on engines and batteries, amongst different upkeep elements. The treatment is to deal with machines as you deal with individuals, Alford says. Present a number of liquids — or coolant — and permit for frequent breaks.
