When the golf course runs a frost delay this normally pushes back all the tee times until the ground has warmed up enough to melt the frost. If frost on the course is ignored and regular play commences it will cause damage to the playing surface and makes the grass susceptible to disease and weeds. What is Frost?
Full Answer
Nov 19, 2019 · When golfers walk across frozen grass, and particularly greens, the compaction can cause bruising underfoot. Barriers between cells break and the plant is killed from the inside. As the temperature then rises, on a putting surface for example, the dead grass turns brown and wastes away. This kind of damage can last well into the spring ...

News, Stories, and Tips. For golf courses that are open all year long we sometimes run into a drop in the temperature overnight causing frost to form on the fairways and putting greens. Some golf courses choose to continue regular play whereas some courses choose to implement a ‘Frost Delay" or play on Temporary Greens.
Sep 12, 2018 · Golf courses, especially member-owned clubs often close simply because the membership or club leadership resist change. There are certain fundamentals few clubs can survive without. Formerly an afterthought, practice facilities are now considered essential by busy potential members with limited time and new golfers.
That’s because clouds trap heat, warming the atmosphere. If it’s overcast at night, you’ve got a better chance of being in the clear for your early morning tee time. If, on the other hand, the air is crisp and you can see the stars, don’t be shocked if you’re delayed by frost on your course at dawn.
But here’s the gist: When grass gets frosted over, the water in its plant cells can freeze and expand. If you mow that grass in its frigid state (or trample on it, or ride your cart across it), those icy molecules can shatter. That’s not broken glass. It’s broken grass. That doesn’t mean you’ve killed the turf, which, in most cases, will recover. But you can see the impact soon after in discoloration. “I don’t want to say it’s just an aesthetic issue, because you can obviously do some structural damage to the plant,” Tegtmeier says. “But most often the impact is visual.” That impact is more readily apparent in the longer grass of the rough, Tegtmeier says. It’s also more obvious when the damage is caused in early season frosts, in, say, late September or October, when the grass is still succulent and growing, and the discrepancy between healthy and unhealthy turf is clearer. It’s much less apparent later in the season, when the turf has started going dormant.
Same thing happens when grass gets wet. The surface temperature of the plant drops to the Wet Bulb temperature. If it drops low enough, frost can form (all the more likely in shaded or lower-lying areas of the course), even if the air temperature hasn’t plunged below 32F. 2. It’s always coldest before the dawn.
Any number of factors help create those conditions. Plain old temperature, of course, but also dew points, wind speeds, humidity and cloud cover.
When that happens, they’ll turn to other tasks, such as edging cart paths or tending mulch beds, that don’t involve treading or riding over frosty turf. 3. The clearer the night, the frostier the dawn. You’ve probably noticed that frost delays are more common after clear, crisp nights.
Neither rain nor heat nor gloomy looks from disapproving spouses can keep avid golfers from their appointed rounds. But frost! Frost will do it. When it forms on courses, it often means delays.
Maintenance crews sometimes do that to get frost off a green, Tegtmeier says. But for a homeowner, he adds, that’s pretty much just a waste of water. “It’s not like you need to use your lawn for revenue,” he says.

Blades of grass consist of 90 percent water, which is why it freezes so easily. If someone or something was to walk on the frozen grass this would cause the plant to break and the grass cell walls to rupture thereby hindering the grass to grow normally.
Frost begins to form at 4°C or lower. It does not have to be below freezing for frost for occur. If the sky is clear there is a greater chance for frost. When there is cloud cover this tends to keep the air and ground warmer, almost acting as a blanket.
Here are a few tips on how and when frost could form. Frost may occur overnight, but it often occurs at sunrise before the temperature begins to rise. Grass absorbs the sunlight and heat during the day and then loses the heat when the sun goes down.
Did you know that the average foursome will take approximately 300 steps on each putting green? And with the effects of walking on the grass not being seen immediately the average golfer may not understand the importance of a frost delay. On average the effects of frost damage are not seen until 48 to 72 hours after the membrane damage has occurred, causing the grass to turn brown and die.

I’ve always been intrigued by golf course and club closures. According to the National Golf Foundation, nearly 1,200 courses have closed in the past 10 years (7.4% of the supply) and more than 700 (4.7%) in the past 5 years. Certainly, as someone who analyzes golf courses and clubs I understand market dynamics and the economics of the golf course and club business. Why this happens is intriguing. However, this topic is often one that is difficult to articulate in a general sense, not only because circumstances vary from club to club but also because it seems as though everyone has a theory.
If the property can’t be developed or there is considerable time between closure and development, the property can become an eyesore. As shown in the picture above, even when the property is maintained (not for golf) it’s no longer pretty. The community that all golf courses and clubs become loses its focal point.
Once frozen just the simple act of walking on a frosted course will cause the grass plant to break and rupture cell walls. The problem lies in that once the membrane is ruptured; future re-growth of the grass blade is significantly hindered. Golf course grass, mowed shortest on fairways and greens and therefore less robust than longer patches, is naturally most susceptible to breakage.
If a frost delay is ignored, immediate damage is not seen. About 48-72 hours after membrane breakage has occurred the grass will turn brown and die. The destruction of the grass, especially on the putting surface, opens the door for the growth of weeds and disease, thus compounding the issue and further devolving the overall condition of the course.
The course manager and thereby duly appointed turf expert decides when the course is shut for frost and more importantly when it re-opens for play – no question.
Ensure that all interested parties are aware that one person (course manager), and one person only, is responsible for closing the course for a frost delay and duly authorised to signify when the closure is lifted, and play can recommence.
Frost is essentially frozen dew where ice crystals develop on the outside of the plant, but importantly ice will also form inside the grass blade itself as the plant cells are largely made up of water.
Understandably for many the ultimate decision may be a commercial one, but we must be under no illusion that foot and vehicular traffic during periods of frost, and particularly as it begins to thaw, is detrimental to the health of the turf across the golf course.
Consider the development of select temporary greens (located sufficiently away from the actual greens) and the possible re-routing of play to avoid those putting surfaces which traditionally remain frozen for the longest. This could permit the reopening of the course before the frost has dissipated across the site completely.
Frost can linger in low-lying and shaded areas long after temperatures have warmed elsewhere.
Shade extends frost delays by preventing sunlight from melting the frost. Pruning or removing trees that shade primary playing surfaces can improve the course’s overall health and reduce the duration of frost delays. This is especially true on holes played early in the round. The shade from a few trees can keep an entire course closed.
Or the plants may be weakened without immediately showing the effects. It can take grass more than a month to recover from this damage.
4. A little frost can cause big delays.
However, cool, crisp mornings bring the risk of frost delays. At some golf courses frost delays are rare, while at others they may be a regular occurrence. How often your morning round is affected by frost depends on the weather and a variety of other factors. Here are five things every golfer should know about frost delays:
Fall is also a good time for superintendents to topdress because rounds are down and they can put down more sand, Kreuser says. “If you’re going to do it heavy in the season, even just wait until the golf season is really shut down and then go out with an application,” he says. Superintendents can also benefit from applying additional topdressing to greens on top of hills that are exposed and susceptible to desiccation.
The EPA has granted registration to new Contend fungicide from Syngenta for control of pink and gray snow mold on golf courses. Contend delivers unique, multi-targeted control for 120-plus days by combining four active ingredients, including Solatenol, a new active ingredient for the turf industry.

Superintendents who use impermeable covers should also pull the covers off as temperatures once again hit 40 to 50 degrees.
Roughly every seven to 10 years, the crew at North Shore Country Club in Glenview, Ill., has to deal with direct winterkill, crown hydration or ice encasement, says superintendent Dan Dinelli. Crew members lay down the woven permeable covers after the course’s Poa annua greens have hardened and soils start to freeze, and remove them when soils begin to thaw. Depending on size, one cover costs roughly $1,200, prior to labor costs. “I like to deep-tine the greens just before covering going into winter with open holes, which is nice to help drain water away from crowns, and the cover prevents the threat of desiccation,” he says.
Golfers are attracted to the backdrop of wonderful fall colors from maples, oaks and beech trees, but the instant a leaf detaches from the branch and hits the ground it becomes a nuisance and must be removed.
It is inevitable as fall arrives there will be frost and with frost comes the dreaded frost delay.
Plant crowns are supposed to lose some moisture in the winter. But wind and dryness in areas such as the Great Plains can push the crown moisture of bentgrass greens below its optimal range, says Dr. Bill Kreuser, assistant professor and extension turfgrass specialist in the University of Nebraska-Lincoln’s Department of Agronomy and Horticulture. “If it’s a hot and sunny winter where it’s just windy and dries out some more, like a desert, then it can get below 50 percent,” he says. “When it starts to get to 40 and 30 percent, then it starts to die off at a lot higher temperature than it would if it was at that ideal peak crown moisture.”
Play is often delayed on courses during the winter due to frost on golf greens. The reason the club should not allow play on greens that are covered with frost is that the turf will be damaged from walking on the frost. The ice crystals in the frost can puncture the leaves from foot pressure.
The superintendent can apply a small amount of water to help remove the frost if the air temperature is not too cold. Running fans to blow air over the greens (the same fans used in the summer) will help to reduce frost problems if the temperature is only a few degrees below freezing. Greens with shade in the morning have lower soil temperatures and usually have the most frost on the grass. The removal of the trees that are shading the greens will help to reduce the delays from frost.
The thawed layer will be saturated with water and becomes spongy. Walking on turf with this condition will cause foot printing and can cause the surface of the green to become uneven. Severe turf damage can result from shearing off the roots as the turf moves above the frozen layer. This damage in areas around where the hole is located on these days will appear as weaker turf later in the year.

Golfers are eager to return to the course on the nice days following long periods of cold weather. All greens usually do not thaw at the same time. Shaded greens are the last to thaw and more damage often occurs on these greens because it is difficult to keep golfers off the course any longer.

It is difficult to explain to golfers that they should not play on greens that are thawing during a warm and sunny day following very cold weather.
