Heavy rain

Early Saturday morning we received 27mm of rain in about 4 hours and caused quite a lot of surface flooding over the course. We haven't had a downpour like that for about 2 years and it resulted in the course being closed for the day. Fortunately we dry out quite quickly and were back open Sunday for the club championship finals. Below are some photos of the flooding.

One of the benefits of the rain was the excellent results we had with the application of Tea seed meal Friday afternoon. We applied it to all the green surrounds and quite a few bad areas on fairways that are shaded all afternoon this time of the year. The results were spectacular.

Course Update

Since the last post we have had unseasonably warm, dry weather which has been fantastic for the establishment of the newly over-seeded fairways. We had seed germination after 2 weeks and all of the thinner areas are coming away nicely and the grass cover throughout has been kicked along with weekly foliar applications of  Ammonium Sulphate.

One of the projects that we have managed to do was the removal of the remains of the old path between the 3rd green and the 4th tee. The old buried rubble was causing a lot of rutting from the cart traffic and was also very difficult to keep moisture in the profile because it was very shallow. Once this material was removed we filled it with fresh soil, added an extra sprinkler and control cable at the 4th tee end and seeded it with Fescue and Browntop. Hopefully we will get germination before winter really sets in.

For some time I have been researching methods to control earthworm castings on our fairways and tees. Since the removal of Thiodan for earthworm control, our fairways have worsened each year to the point they became very muddy in areas certain times of the year. We haven't had much success with the various methods we have tried and products like Earlybird were very expensive to apply to large areas. Recently I was told about a granular version that had just been released and was considerably better value for money. I was very quick to get some granules to try out before we got into the "muddy" season. I have trialled it in about 10 areas of the course that has historically been very bad for castings. Once applied it was heavily watered in and within  10-15 minutes hundreds of earthworms were at the surface. Since the application we have had over 50mm of rainfall over weekend and thousands of earthworms have surfaced. Very impressive! It will be interesting to see how long the earthworms will be suppressed for until another application is required.
