Spring Greens

No, not the kind you have served with your evening meal, it’s a reference to the putting surfaces we are experiencing here at TLGC.

Some members maybe concerned that the greens are not being watered sufficiently and that this is why the surfaces are only slowly recovering from the essential early Spring scarification and sand injection which created the lines you see now.

The correlation of lack of rain fall, and the slow recovery from the maintenance work seems to make sense but this in fact is not the reason.

The soil moisture levels of the greens have been measured and in general are within the tolerance required. This doesn’t mean the greens have not been watered though. The irrigation system has been used as necessary and areas that are more susceptible to drying out such as the 9th green and the back of the 18th green have been receiving additional hand watering. This though is to simply keep the grass alive as unforatunately the temperature of the water that comes from the irrigation is extremely cold and further holds back the soil temperature. To try to reduce the effect of the cold water, any hand watering is done during the warmest part of the day.

For the grass to grow and the putting surfaces improve we have to be patient and wait for the soil temperatures to rise. The consistently cold nights in addition to the cold water being applied has meant that growth is very slow, for consistent growth the soil temperature needs to be at least 6-8 degrees Celsius 24 hours a day. The fact that we have experienced frosts nearly every morning shows this has not been close to being the case. Once the night time temperatures are consistently higher you will start to some significant growth and improvement. The rough will also get a bit thicker though, can’t have it all!

Finally, we continue to follow the guidance provided to us by STRI and this will mean in the next few weeks further spray applications with regards to moss. Followed by a verticut (light scarify) of the greens, over seeding and top dress. This is all necessary work to continue the long term improvement of the putting surfaces.
