There 4 contributing factors that lead to the failure of the turf on those fairway’s -
1. There is little to NO topsoil on those fairways. They consist of all clay and rock with very little dirt on top. The root system is very shallow.
2. There is a layer of thatch that has developed on the top that does not allow water or the root system to penetrate.
3. The variety of grass on our fairways is predominately Kentucky Blue Grass that does not tolerate the heat and stress very well.
4. A very limited water system and no drainage help contribute to this problem.
These fairway’s are aerated every fall, fertilized the same as the rest, mowed at the same height and we have tried applying different amounts of water, all with no positive results. Every year if the weather gets hot and we receive heavy rainfall during the day and then sunshine, this turf goes dormant.
WHAT CAN BE DONE?
Other than a very costly renovation that would close these fairways for a long time we would like to -
I have lined up to try a machine from the TORO rep that is called the “SEEDARATOR”. This machine uses a solid 3 inch tine to punch holes and shatter the soil, breaks up the thatch, then puts seed into the soil, grooms and rolls the surface, all in one operation. I would like to try a different variety of grass on these holes, a straight “rye” grass that is much more heat tolerant and handles the stress better. We would be doing this right after the club championship weekend. Not knowing how this will work out or how long it will take, we will probably try this on #15 first and then possibly the other 2 if we have positive results. There is not much of a downside to trying this as I don’t think we can make it any more “unplayable” than it already is. The cost of the seed is not a major factor.
I have brought in many “experts” in the field to look at these holes and all have the same ideas as to why this happens but no easy solution to fix the ongoing problem. I am always open to everyone’s thoughts and appreciate your patience as we continue to try and improve your golf course.
