In the Spring and Fall of each year, Torrey Pines will close briefly to conduct important maintenance to keep both North and South courses in world-class conditions. Maintenance includes:

Aerification

Each golf course must undergo a biannual aerification process in which small holes are inserted into each playing surface in order to maintain the continued health of the turfgrass.

Overseeding

To maintain world-class conditioning throughout the winter months at Torrey Pines, both golf courses undergo a wall-to-wall process of installing perennial ryegrass seed across all tee boxes, fairways, roughs and approaches. This process involves drying down the summer grasses for a period of two to three weeks prior to the overseeding date. 

Players can expect the surfaces to appear brown in color, yet play firm and fast during this period. Cart-path-only rules are in effect through the overseeding process until further notice.
