Autumn Green Renovations at Normanby Hall Golf Club (August 2020)

Last week the Green staff at Normanby Hall Golf Club undertook the annual greens renovations work.

This was done to keep good playing surfaces, maintain healthy grass, allowing air into the roots, to prepare the green for the winter months.

The work involved

First 2 days – The greens were scarified 4mm deep removing any organic matter. Then hollow cored using 8mm diameter coring tines to the depth of 30mm removing thatch and breaking up any compaction.

The cores were collected, these are kept and reused on the course when patches or paths need maintaining.

Greens were then over-seeded using a mix of different Fescue grasses at a rate of 5-6kg per green.  This is applied using the Redexim Charterhouse 1600 speed seeder.  Allowing the seed to be placed directly into the turf rather than leaving on the surface.

Day 3 & 4 – An application of Messingham 35 sand was applied (roughly 1 to 1.5 tonnes per green).

This encourages deeper rooting, helps smooth the surface and improves air circulation and surface drainage.

Once the sand was applied, it was then solid tined using a 12mm diameter tine, going 9” deep to help break up any compaction, also to create a hole for the sand to drop into. This will help with drainage.

Greens were then bashed, using the sweep & fill brush, which is designed to get the sand into the holes by having counter rotating brushes keeping the sand between each brush, allowing it to drop down into the holes.

Sand was left to dry for an hour, then brushed a couple more times in different directions, making sure all the aeration holes where filled. Any excess sand was blown away from around the edges. Pins were changed and greens put back in to play.

Day 5 – All aeration and topdressing was finished. The greens were given a soft brush to remove morning dew, followed by rolling with the turf iron.  This helps to smooth the putting surface, ready for play.

The following weekend the greens were rolled both days, no cutting took place to allow the grass to rest and settle down.  Although small amounts of irrigation were applied, this helps to wash the sand into the playing surface.

The mowing height has been lifted from 3.5mm to 5mm for a couple of weeks, allowing the seed to germinate without be collected when cut.

Monday 24th – the morning dew was removed using a soft brush. All greens were left to dry, once dry they were all cut without collection boxes on, ready for an application of fertilizer the following morning.

The fertiliser being used is a slow release batch which means it will release nutrients over a period of 3 months, helping to thicken the sword (coverage of grass) and support disease resistance.

So that is what happened this year on the greens’ renovations. By doing all this kind of work, it will only help the greens improve and create better playing surfaces for the future.

A huge thank you must go out to F G Adamson & Son, for allowing us to use their equipment. Without them, this would not have been possible. And finally thank you to the members for their patience during this time.
