GREEN CLIPPINGS

The course has dried out finally!

What has this meant for our boys on the greens staff? 

The course staff were able to attend to major leaks of the storm water pipes that are a big key to taking large amounts of water off the course. With help from Kev and his excavator, we were able to repair all 4 leaks, and removal of old pipes located down the 5th hole.

The small jobs suddenly became a larger project and I can’t thank our members Ron Newton and Peter Hughes enough, who dedicated their days and some late afternoons with helping with the repairs - thanks guys!

The rest of the course is back to its desired length, with all rough areas mowed and tees and collars cut to desired heights. Tee dome markers and permanent plates have had a refresh of paint; dam walls and banks have been cleaned and snipped with herbicide applications to treat weeds in our dams.

Greens have been fertilised with a granular application, meaning this has given the couch grass a small uplift of growth before we renovate next month. Greens are currently running slower with heights raised to 4.2 mm minimising stress, more so for our shaded greens that already struggle during this time of year. Once we move into renovations and see warmer night temperatures, heights will be brought back to a lower cut around 3mm.

A lot of members have raised the questions about the foreign grass through certain greens. I would like to explain the best I can why they have not been removed, and also my herbicide programme of fixing the solutions.

With the main carpet grass issue to our greens, I am confident in saying that has been there for several years! This grass has not arrived overnight, and past superintendents have had to deal with the same problem with not having a product that will remove such large amounts which will not harm the blue couch grass - e.g. the worst greens are the 2nd and 5th. Unfortunately, in the trade of horticulture there is not one herbicide product that is legally registered to remove this grass without killing the blue couch grass.

However, small patch areas the size of a golf ball can be removed by hand labour, with the repair area not being too large for recovery. With the new development to the golf club, greens such as 2 and 5 will be put on hold because with the surface area contamination being more than 60%, the only option is to resurface the green.

This is a perfect time for the course staff to proceed with all small weeds as there are many nutrients applied to the greens after they have been scarified at renovations.

With that being said, this week all course staff are working hard removing small patches of carpet grass, crows foot, and an application was done on Tuesday with a registered herbicide that will kill the winter grass and Mullumbimby that is present on the 328 greens.

RENOVATIONS

This will take place on Monday 2nd and 3rd of September with 9 holes closed each day.

Monday: all greens will be scarified removing thatch at a depth of 4mm.

Tuesday: all greens and selected tees will be cored with a 12mm solid tine followed by a heavy top-dress of sand.

After these procedures, we will follow with watering-in our several amendments/ fertilisers with irrigation running all week.

As mentioned with our last renovations, I please ask members not to touch any valves whilst the water is running as it could cause severe damage to our system.

With the weather looking a treat, myself and the team are confident in removing a large amount of foreign grass to the greens’ surfaces and seeing a good result from our course renovations this winter.

Happy golfing and hopefully another sunny month for everyone.
