Green Speed – new facts

Sward refinement

Work has started on green surrounds to refine the sward with the verticut units. 

These pull out large amounts of dead material and trim any lateral growth as well as reduce any matting of the foliage. 

This provides a firm, tidier surface as well as reducing the chances of disease breakouts. 

Best done in dry conditions we will double cut behind to tidy up the surrounds for play. 

Work will start on tees following the completion of surrounds. 

Greens aeration

Aeration with a 10mm solid tine is underway on greens. 

The tines are working to a depth of 3.5″ to allow air into the roots of the turf and help alleviate any surface compaction. 

We are double rolling immediately behind to reduce disruption. All of the even numbered greens are being completed today with the remainder being finished tomorrow. 

Sward refinement

The greens are being brushed and cut this morning to help remove some of the coarse grass. 

The mower is following immediately behind with the turf conditioners engaged to further lift the grass prior to mowing. 

We can expect a larger volume of clippings this morning and as a result a small increase in speed and smoothness. We will repeat the process several times over the coming week or so ahead of overseeding to help reduce competition while the seedlings germinate. 

Etiolated tiller syndrome

Etiolated tiller syndrome or ‘ghost grass’ is the disorder we are starting to see on the greens. 
This has been accelerated by the application of a selective herbicide to control Pearlwort. 

The grass shows soft increased growth but with stems that appear white due to the lack of chlorophyll. The turf appears as though it has been growing in poor light. 

There is nothing to be concerned about and an application of Magnesium and Potassium will help the colour return. 

Greens aeration 

We have taken advantage of the damp conditions to slit greens. 

The knives of the slitter penetrate 5″ into the surface and cut a semicircular slot. This allows air and moisture to enter the rootzone and maintain turf health. 

As seen in the photos there is minimal disruption as the greens are rolled immediately behind. We will slit again 2-3 times over the coming weeks in slightly different directions. 

We can complete all greens in 3 hours which is vastly quicker than solid tining. This process does not replace the tining however and that will be carried out in autumn.
