The rough is growing at a rate keeping both golfers and maintenance people unhappy. I'd like to provide a little information about this situation.
1. Rough turfgrass grows fastest in spring.
2. Since April 1st, 6.50" of rainfall has fallen on Potowomut. This factor is the most important one affecting unruly rough conditions today.
3. After a brutal 2010 summer, rough was fertilized to aid its recovery last fall. This also is affecting rough height and quality, especially when combined with both factors above.
The height of cut on Potowomut rough is 2.50". This height of cut is NOT changed during the year. Lowering the height to 2" would result in thin, less reliable rough during summer months because of the corresponding shrinkage of the turfgrass root system. Larger areas of rough would go dormant in summer months, or would die completely. During a past year, 2" rough was maintained as an experiment and was a rated a miserable failure because of poor rough condition during July, August and September. Remember, most rough turfgrass is NOT irrigated during summer because the sprinkler heads don't throw water far into the rough.
Normally, it takes us a full 40 hour week to mow the rough one time. The operator begins Monday morning at 6AM, and completes mowing eighteen holes by late Friday afternoon. For an example, rough on the 10th hole was mowed on Monday morning May 2nd, and will not be mowed again until Monday morning May 9th. Mowing rough twice a week would require investment in both new equipment and more manpower to complete.
For this month, we are working extra hours to try and stay ahead of the rough. We will mow holes with the thickest rough a second time during the week or during the weekend. We expect the rough to slow down during later May and June if normal weather patterns return.
On a positive note, we have begun mowing the "first cut" of rough this week, three weeks early.
