Update

It's been busy I have verti drain greens 20mm diameter x 400mm long tines down to a depth of 275mm with heave on, once all greens were done the following week we hollow core greens 12mm x 125mm tines down to a depth of 85mm, we had a lot of cores to pick up which took longer than hollow coring greens & hard work. 

Once all that was done the following week I vertical cut greens followed up with top dressing greens at the same time applied seaweed meal, then brushed & drag mat in.

 It was hard going but we manage to get it done, due to the hard work I took time off to rest a week later coming back to work found greens have disease hit the greens due wet weather & volume of play.

 Now we are into winter grass has slowed down & we are left with scares from the disease, grass is growing back but very slowly will take time & when soil temputures are up I will overseed the greens to help the recovery of the greens in spring time. Now we are into winter I have started on drain jetting drains the machine is an absolute god send as it save time & clean the drains complety, making drains more efficiently. In return course will dry up that little bit quicker, the only problem with the drains are they are to small 2" pipe which means they silt up quickly, with any new drains I be putting in bigger size pipe 4" -12" pipe. 

 I'm been looking at the 14th why it has becoming wetter, done some investigation found that the water is not getting down to the drain, what's causing this is a build up of thatch & moss which holds onto the water the trees haven't help staving the grass from sunlight & air movement grass needs sunlight to help it grow (photosynthesis), but what I am doing is installing drains in at 14th which help with the wetnest but this is not a quick fix but a step in the right direction, over time with more drains install will benefit the course big time!
