Course Management Terminology and Science

Message from your Head Greenkeeper – All procedures are carried out at certain times much dictated by weather conditions at a particular time of year. Many procedures in Autumn need to be well in advance of any frost risk. I hope you will understand that we do not do these things to the course to get in anyone’s way or to annoy anyone. We are simply trying to create a golf course that is playable all year round. Thank you, Ryan.

Dressing greens. Top dressing greens is done to help dilute thatch build up within the greens surface, it is also done to improve surface evenness which in turn will help with more consistent ball roll.

Sorrel rolling. Sorrel rolling is a way of aerating the top two and a half inches of the greens surface, this helps with microbial activity. Microbes help to breakdown thatch, they turn it into nutrients that the grass plant can use for growth. Sorrel rolling is also done to help with water infiltration through the soils surface.

Brushing greens. Brushing greens is done to move the sand top dressing into the holes that the sorrel rolling has left, it helps to improve the evenness of the turf surface.

Leather-jackets, Chafer grub & Worms Treatment – In September Leather-jackets and Chafer grubs start to become active, eating the roots of grass plants.They are laid into the soil by Crane flies and Chafer beetles. As the soil profile becomes wetter, typically in autumn, worms come to the surface causing worm casts.

Fusarium Treatment – Fusarium patch (Fuzz), a fungus, is very active in the autumn. It loves the warm wet conditions of heavy morning dew with the summer warmth still in the ground and can spread vigorously. The problem can be accentuated by the treatment for Leather-jackets, Chafer grubs and worms which tends to kill some of the biology of the soil profile making the grass more susceptible to diseases like Fusarium.

Verti-draining – A process much like a pitchfork but on a massive scale. It is designed to punch holes deep into the soil profile. At the bottom of the each hole it produces a flex which fractures the subsoil. which , in turn, creates air and water movement through to fractured ground. These spaces are then taken up by fresh root growth, giving a stronger grass sward and deeper roots to take nutrient and minerals from the soil profile.

Top Dressing – We use 100% sand top dressing because of the clay based soil. Sand helps water and air movement through the soil depth using the pore spaces in the sand particles. It also helps to create a level surface for more even ball roll – A mixture of Bent grass seed is used, being perfect for clay based greens. Tends to be done in autumn before any risk of frost which would damage the seed.
