As part of an ongoing process we promised to begin working hard on remedying this by putting in place a more aggressive aeration programme which would take away more thatch and introduce more sand into the surface to get them back to how they used to be. In Spring we cored with 10mm diameter tines instead of the 8mm tines we used previously (which also go about 30% deeper), and this has had a noticeable effect over the summer, with our greens being slightly firmer and better draining than last year. This is not an overnight remedy though, we will be coring again in a month's time to further progress the greens.
Another change we have made is the introduction of a Wetting Agent programme in 2018, to help the roots have access to water deeper into the profile of the rootzone, promoting healthier growth in drier times.
Over the course of 18 months to 2 years we should see a vast improvement to the firmness and drainage of the surface, aiding better gaseous exchange for the roots which will lengthen them, and the greens will then become more resistant to disease and be a much better, year-round putting surface.
As many will notice we are still suffering with disease on some of the greens (mainly 6, 8, 11), but we will be monitoring this in the coming days and spraying with fungicide if it worsens. As the greens get better due to our new aeration regime this should become less of a problem each year.
When we core the greens in September we will be hiring a Sweep & Fill machine, which will disperse the sand into the cores much more evenly then our previous methods, and get rid of any excess sand on the surface, meaning the recovery time from the aeration will be MUCH quicker and the greens will be back to normal a lot sooner.
