Let's talk frost!

While much of the U.S. deals with winter’s brunt, us golfers in sunny Scottsdale, Arizona are still playing away. 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:

1. Crunchy grass is vulnerable to damage.

Golf course turf is normally resilient to traffic, but when ice crystals form inside the plants, they become brittle and vulnerable to damage. Walking or driving over frost-covered grass may rupture plant cells, leading to dead turf. Or the plants may be weakened without immediately showing the effects. It can take grass more than a month to recover from this damage. 

2. When it comes to frost delays, location is everything.

Many of us have looked out our windows at home and seen no signs of frost, only to find a frost delay when we reach the golf course. This is because frost can linger in colder microclimates long after other areas have thawed. North-facing slopes, low-lying areas and areas sheltered from the wind are especially likely to remain covered with frost. If you are worried about a potential frost delay it is best to call the golf shop to check on conditions at the course before leaving home.  

3. Closely mown turf is at high risk.

Frost damage can occur on any part of the golf course, but it poses the greatest risk to closely mown turf. Putting greens are particularly vulnerable because they experience the most concentrated traffic. A foursome typically takes 300 steps or more on each putting green; if there is frost present, all those steps could cause serious damage.

4. A little frost can cause big delays.

No signs of frost on the first tee? That doesn’t mean you will get the “all clear” sign. If frost remains in areas that are unavoidable early in the round, the course must remain closed. It is also important to remember that once the frost is totally clear, the maintenance staff will need time to catch up on course preparations before play can begin. 

5. More light goes a long way.

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.

If you have any more questions regarding frost, please do not hesitate to reach out!

Follow up from last week

This week we received some concerned feedback from last Monday's Minute regarding the length of time it takes to spray and eradicate weeds. So I thought it could be helpful to follow up on our weed co

Weeds throughout the course

Why do we have weeds and how do we combat them? These late season rains have created the perfect conditions for weed seed germination- causing somewhat of a weed bloom throughout the golf course. We t

There are countless factors that play into frost more than elevation and proximity to one another. First point that needs to be made: while Terravita, The Boulders, Dove Valley, and Legend Trail are all at ~similar~ elevations, they are not exactly the same. In addition, within the individual golf course you can have significant elevation changes that will encourage or discourage frost development.

Amount of irrigation that was put on the golf course the night prior can impact frost. Occasionally, if I see low temperatures coming for the next morning, I will skip the irrigation cycle that night so that there is less moisture on the grass to potentially freeze the next morning. Although, when you have several low…

I’m noticing that the Boulders-Dove Valley-Legend Trails, that are our neighboring courses, are experiencing 30-45 minute frost delays in the past days, while we are under 1 1/2 to 3 hour daily delays. Same elevation, within minutes. Can you clarify why it’s happening here but not there?
