How we choose our drainage stone

How we complete a drainage task

We’ve identified the problem areas on the greens, then we prioritised them into what needs to be done first. Once we’d completed the worst two areas (1st green, 13th approach) we moved onto the 3rd green, the very front portion.

The front part of the green was a problem area, causing the green to be off many times due to holding onto moisture. The plan was to install over 50m of pipe, a drain running around the front then off down the hill to be collected in a carry away drain beside the 4th green, a lateral from on the green would also run into the system.

The way we complete the task is a little different than you would in your back garden due to the quality of the materials we use. We use a 2 tier system, where we have 6mm stone placed over the pipe with rootzone then placed directly onto the drainage stone. The way you would carry out the task in your garden would be to use 10-20mm limestone, then place a membrane to stop the soil migrating into the stone.

The drains are 600mm deep (all hand dug!), the pipe is 100mm.

The pipe is installed then the 6mm drainage stone is placed up to 300mm from the surface. Rootzone is then placed on top of the drainage stone to within mm’s of the surface, this allows up to place turf taken from the 7th nursery green on to the new trenches.

We did exactly the same on the 1st & 13th. We are hoping to complete small tasks on the 4th & 10th green to improve the putting surfaces.

Greens update December- January

Greens update December- January

 

Having given you an email to outline my intentions for the greens this winter I will go through what we have been able to complete.

 

Aeration is the biggest task we have over winter, to keep the surface open to allow water to get through the soil profile as quickly as possible. We completed 5 aeration procedures during November. In December and January we’ve only been able to aerate 3 times due to weather being too wet (Dec 106.5mm, Jan 87+).

 

We decided to try put small amounts of dressing on the greens in both months, this hasn’t been possible due to the weather, although we may have thought of a way to get round this by applying it with the walk behind spreader.

 

The greens had a feed put on mid Dec, a 3-0-14 was applied. This got the greens looking really good, and there are still in decent shape. Another feed will be applied next week. We was hoping to apply some liquid iron mid Jan, this was not possible due to frost.

 

Unfortunately due to the mainly mild winter we have had, fusarium has been present on quite a few of the putting surfaces. We have spot treated twice, due to not being able to get out with the big sprayer. We spotted new signs last Friday after the greens had thawed out, it was decided by Graham and I that we would come in and spray on the Sunday morning as the only window we had was then. We will be monitoring this throughout the rest of the winter. Liquid iron will now be applied mid Feb, this will help harden up the plant whilst also giving us good colour to the sward.

 

Two application of a penetrant wetting agent have also been applied, we were of hoping to have applied one more by now but this hasn’t been possible. This will happen next week if the wind isn’t too strong.

 

Rolling the greens stopped at the beginning of December due to the moisture levels becoming too high. We will start rolling the surface when conditions allow. 

 

 

As we speak we have dug and back filled two drainage areas on the 1^st & 13^th greens. These were always problem areas so we have installed 100mm pipe at depths of 750-600mm. We have started to install a similar system to the 3^rd green. We are also going to hopefully look into the problems on the 4^th & 10^th.

 

Proposed plan of works up to may 2015

 

Feb,

 

·         Aerate (when possible)

·         Cut (weekly)

·         Apply feed (early feb)

·         Apply liquid iron (mid-late feb)

·         Apply penetrant wetting agent (early feb)

 

March,

 

·         Aerate (when possible)

·         Cut (weekly)

·         Apply 8-0-16 +2%Mg + 4%Fe (mid march)

·         Start verti- drain 23^rd & 30^th followed by top dressing

 

April,

 

·         Last verti- drain 7^th followed by dressing. We may also micro core some wetter areas of the greens when we carry out the verti drain, areas like front 1^st, front 3^rd, left 4^th, front 5^th, front 6^th, 10^th etc.

·         Start summer wetting agent programme.

·         Start aeration programme of every other week followed by light dressing (start 13^th)

·         Apply feed (last week)

 

All of the above is affected by weather, hopefully we will be able to complete all of the above, if not we prioritise the ‘must do’ tasks.

 

Please follow us on twitter @ashtonleagreens , we give daily course reports and sometimes put pictures on of jobs we’ve completed.

 

If you have any queries of any of the above please email us on greens-ashtonlea@hotmail.com.

Small drainage work on the greens

Drainage work on the greens,

 

We have started on a drainage plan to improve certain greens this week.  The first job was to install a new drain to the front of the 1^st green,

This is a 100mm perforated pipe, installed to the depth of 600-750mm. It’s been covered with 6mm stone up to 300mm of the surface, rootzone will then be used with new greens turf being laid.

We feel this should solve the problem at the front of the green, we can always run more drains into this large drain in the future if needed.

Next week we are going to start the challenge which is the 13^th approach. This is the reason why the green has been off so often in the last few weeks

My plan is to install one main drain with 4 laterals running into it, this will hopefully catch the water before it gets onto the green, and also firm up the area.

We are also going to shape the ground so it helps us direct the water where we want it to go, the main issue we will have on this job is the amount of fall. Unfortunately the drains in the greens are not that deep.

We are going to install a similar system to the 1^st green on the 3^rd green

The two other greens I am going to focus on are the areas on the 4^th & 10^th. On the 4^th we will dig down on the problem area in the middle of the green exposing the drain that is there, replace the drainage stone, replace the rootzone and trim the turf of thatch.

On the 10^th the target areas will be the middle portions on either side. The plan is to bore down with a post borer as deep as it will go, backfill with stone then top up with rootzone, the turf will be re-laid with the majority of the thatch removed.

I have plans to do a short term and long term report on the greens in the near future that I will email out, it will explain what has been done so far, and what we haven’t been able to do and why.

If you have any feedback please e-mail us at greens-ashtonlea@hotmail.com
