A weird sort of week with the smoke haze blowing in one day and out the other with gusty southerly winds followed by equally gusty northerlies.  At least Thursday gave us some easterlies which sometimes brings some rain and Friday changed it up a bit with a gusty north easterly.  Which all adds up to lots of leaf debris.  We did manage to get the River course tees scarified and cleaned up but no aeration as it is too hot and dry.
Monday mornings sun @ 6.30 am with smoke haze.
Everything is set for the greens renovation on the River course that will commence on late Sunday afternoon.  We have had some light rain the last couple of years just to annoy us and also impact on the tidiness of the tasks performed.  And lo and behold there is rain forecast for Sunday!!  But we will certainly take anything we can as far as rainfall is concerned in the current conditions.
At this stage it is planned to scarify the greens in at least four directions up and back on the same line so at least eight passes over the green @ 5mm depth.  That will then be followed up with the de-thatchers set @ 3mm depth in two directions up and back.  The scarifiers and de-thatchers we use are mounted on the greensmowers and are pictured below.

The top photo is the scarifiers and you can see brushes in between the blades that help throw the material in to the grass catchers.  Golfers often refer to scarifying as ""tramlines"".  The de-thatchers below are what is used on a regular basis on the greens but in this instance will be set at 3mm depth whereas for routine operations they are set to ground level height with the weight of the unit allowing the unit to contact the surface.

Scarifying heads with brushes evident.

De-thatching heads with a narrower spacing.

After that operation the greens will be hollow tyne aerated using tungsten tipped tynes to a depth of 50 - 75mm.  The photo below shows the tynes which are classified as 9.7mm or 3/8 inch which isn't quite right when you look at how the taper of the carbide tip reduces the opening.  Following the hollow tyne the greens will have some amendments / fertiliser added and then finally sanded.  Due to the high sodium levels and therefore stressed growing conditions recovery may be a little slower however given the soil test results the greens are in fairly good health.

Even though the renovation is on Monday it isn't until you get a start that you can figure out exactly what will be done as the weather and soil conditions dictate just what can be done.  A light shower of rain can cause havoc with dirt sticking to rollers and clogging up the mower heads. Sometimes depending on the soil conditions it is hard to pull a plug out, especially with the carbide tips which last a lot longer but tend to lose their sharpness and therefore clean penetration through the surface.  So despite the best laid plans you sometimes have to fly by the seat of your pants as the saying goes.

Tynes mounted and ready to go.

Taper very evident.
