Temporary Greens

Frequently Asked Questions


Temporary Greens are used simply to protect the main greens from excessive wear and damage during adverse weather conditions. Continuous foot traffic during poor conditions can create detrimental effects both short and long term to the green surface and the soil stability.

They are also used on the odd occasion when contractors/staff safety is required due to greens maintenance; or when the greens are recovering following maintenance or vandalism.

How do we decide when to use a temporary green?

All Greenstaff follow a procedure and set guidelines which determines whether a temporary should be used.
  • Walk on and walk off areas (traffic management around greens and on greens)
  • Standing water (localised flooding/surface water)
  • Unstable putting surface (root shearing/compaction)
  • The long term detrimental effects to the playing surface
  • During a thaw following freezing conditions
  • Light dusting of snow or thawing snow
  • Undergoing maintenance 
Why can the temporary not be cut shorter? 

The temporary greens are essentially the approaches. Due to the nature of some temporaries on approaches also suffering due to poor conditions; additional temporaries are cut out in-front of the approaches on the fairway. Both the approaches and additional temporaries are mown to a height of cut of 10mm.
The maintenance and attention given to the main green surfaces is not applied to the same level to temporaries. This is simply due to the performance of the area and costs.

If the temporaries are cut shorter, the risks on how they react to wear increases. The plant will become weaker and less tolerant to wear. The opportunity of disease developing during high disease pressure conditions will also increase. Ultimately cutting them shorter could potentially render them completely unusable.

Greens Maintenance - Drill & Fill


The main focus of attention of greens maintenance in recent years has been in and around the upper profile.

Hollow-Coring is of course the most normally recognised procedure for improving rootzones and for reducing organic matter. In recent years new techniques and alternative procedures have come to the forefront. Several years ago we concentrated solely on the upper profile, undertaking the Graden with Sand Injection. This procedure was carried out twice. Soil samples tested, reported that organic matters levels in the top 20mm were low, below 4%.

Attention was then afforded to moving maintenance into the lower profile following the success of the Graden to improve more on drainage and to link up with the surface. The next step was the Sand Injection procedure that was carried out last August. Like most Greens Maintenance techniques the best time to undertake work is when conditions are favourable for the best possible chance of success and quick recovery. Which is genuinely somewhere in August and September.

Having tackled the upper profile and then moved to lower in the profile, this years maintenance is focusing even deeper still. The Drill & Fill process is not a new technique, it was actually carried out here at Langley Park some 13-14 years ago. It is hoped that it will not take that long this time before it is carried out again. Linking all the different depths of maintenance is the target. What will determine the next type of maintenance is how well the greens and our next set of soil tests perfom. 

DRILL & FILL


The Drill & Fill aerators provide improved solutions to: slow drainage; compaction; thatch;black layer and poor grass growth. These aerators will help us to improve our fine turf areas and help to keep them in play for longer, improving rootzone and the microbial environment.

The Drill & Fill advantages :

  • Relieves compaction instantly
  • Improves drainage rate
  • Penetrates to a depth of 310mm
  • Backfills instantly with soil amendment
  • Accelerates infiltration rate
  • Promotes deeper rooting
  • deeper rooting means better sward performance and soil structure 


Effective Aeration

The Drills remove soil allowing lateral movement within the rootzone and releasing compaction pressure. Drilling improves surface water infiltration and percolation, reducing the soggy, spongy conditions common in "push-up" and old clay-based greens. Deep holes encourage deep, strong roots and drilling depth is always consistent.

Precise Backfill

The Drill & Fill puts the soil amendment - sand mix directly into the rootzone. this holds open the drainage channel giving extended life to duct life. Langley Park is using a taylor-made soil exchange with a sand mix blended with zeolite amendments.
