Annual Bluegrass removal on Zoysia fairways

In order to maintain a high level of playability on the Zoysia fairways, many cultural practices are employed such as; aerfication, adequate fertilization, proper watering practices and increasing light to the plant. These practices improve the health of the Zoysia grass, reducing unwanted weeds such as Annual Bluegrass (Poa annua). Each year the fairways are sprayed twice with a herbicide to eliminate any Annual Bluegrass, the encroachment of the Annual Bluegrass, if left untreated will reduce the health and playability of the Zoysia. The below photos were taken during the recent application to the fairways at Hyde Park.

Golf Course Closed

The golf course is closed today due to the frozen/thawing turf, we hope that the warm weather will allow for play on temporary greens later next week.  Attached is a further explanation from the USGA concerning the impact of freeze and thaw effects on the surfaces from foot traffic.

"Traffic damage on frozen turf areas usually occurs during periods of freezing or thawing. The most devastating situation occurs when the grass blades and the upper one-half to one inch of soil has thawed, but the ground beneath their level remains frozen. Traffic will create a shearing action of the roots, rhizomes, and crown tissues at this time. This is comparable to cutting the plant tissue from the underlying root system with a sod cutter. Complete kill of leaves, crowns, and rhizomes can occur if the temperatures soon drop below 20° F. Symptoms from this severe injury include whitish to dark brown leaves that may mat on the surface. Once temperatures allow thawing to a depth of three to four inches, the probability of turf damage declines since about 75 percent of the root system is in the upper four inches of soil. Frequently soil probing is the only positive way to effectively monitor the freezing level. Traffic should be adjusted accordingly (USGA, 1984)."
