|Annual Bluegrass has started to re-colonize the areas that were damaged last winter|
1. Collar Aeration - As the surface that immediately surrounds the greens surface, collars lead a comparatively hard life compared to greens surfaces. There is a significant amount of mechanical stress due to mowers turning or being turned on the surface as well as all the other mechanical stresses that the collars are exposed to in order to maintain them as a high-quality playing surfaces. To keep the condition of the collars at a high level, additional core aerations and topdressings are done to relieve compaction and keep the flow of water and oxygen to the rootzone. This aeration is done in advance of the drill and fill aeration scheduled to begin on November 3 after the golf course is closed for the season.
2. Short grass - The process of reviewing and expanding the short grass areas on the golf course is ongoing. The amount of short grass areas around greens have been increased in the past number of years based on the recommendation of the consulting golf course architect, Ian Andrew. The short grass areas can help speed up play while adding another level of complexity and decision making for the better players. Increased short grass areas can also help to improve the surface drainage patterns on some of the greens surfaces, which will help to reduce the potential for winter injury. In addition, the fairway areas that have been converted to rough will continue to be improved. Converting an area from fairway turf to rough turf requires fewer inputs of fertilizer, chemicals, water and fuel to maintain the area.
3. Tee/Fairway Aeration -
Tees and fairways will be topdressed with sand and
aerated during the next two weeks. Incorporating sand into these playing surfaces
improves the growing medium and creates a firmer hitting surface.
4. Drill and Fill Aeration - After the golf course is closed for the season, drill and fill aeration will take place on the greens followed by a conventional solid tyne aeration using 5/8” tynes. The drill and fill aeration improves the internal drainage properties of the greens which helps the surfaces remain firmer during periods of heavy or consistent rainfall. This is especially important when heavy rain is experienced during periods of extreme heat like this past summer. The improved drainage properties help the moisture to move through the profile away from the surface. This process also allows the greens to be flushed, which is the principal defense against the negative impacts of salts from the irrigation water accumulating in the rootzone.
5. Tree Management – The process of evaluating and improving growing environments will continue through the fall and winter. The damage and subsequent recovery process showed the importance of a healthy growing environment as the poorest growing environments (5,8,12,16,) sustained the worst damage and experienced a slower recovery compared to the superior growing environments (2,6,14,17,18)
|Shade contributes to weaker turf and increases Annual Bluegrass invasion|
The usual winter preparations of winterizing the irrigation system and making applications of winter chemical protection will also be done following the closing of the golf course for the season.
