It was certainly a busy week on both courses. Many of you may have noticed the wet conditions yesterday. We watered both courses heavily Wednesday night in preparation for Thursday's cold front. The added moisture in the ground will provide a buffer to the lower temperatures and protect the grass from the high winds and low humidity which are expected to last through today. The course will certainly be more playable today and through the weekend.
Throughout October we have been preparing the greens on both courses for Winter. This week was no exception. We slightly raised the mowing heights, topdressed, fertilized, and sprayed both the North and the South. Putting speeds on both courses should pick up a bit with the cooler temperatures expected this weekend. All of the greens are healthy and are ready for winter. If you have not played recently then we encourage you to come out and play either course.
I have been getting a lot of questions regarding fertility and pre-emerge for the home lawn. Fertilizer decisions are best made after looking at a soil test. However there are few simple guidelines that will help you stay on track. For warm season grasses I like to apply phosphorus in the spring, nitrogen in the summer, and potassium in the fall. For example this week the the greens received a combination of soluble potassium nitrate (13.5-0-48) and granular sulfate of potash (KMAG) or 0-0-22. The fairways, tees, and roughs were also received applications of KMAG last week.
Now is the time to apply a pre-emergent herbicide. I suggest using a combination fertilizer and herbicide product. Look for a fertilizer high in potassium such as a 10-0-20, that contains a herbicide such as prodiamine. This particular product can be purchased at Winfield Solutions here in San Antonio. Always use caution when applying pesticides. Follow all label instructions and ensure that your application equipment is properly calibrated. DO NOT APPLY a pre-emergent herbicide if you your yard is severely stressed from the drought or if you are planning to overseed. In addition, use caution around flower beds if you are planning on planting any winter annuals.
