Aeration

In general, golf courses in Hawaii aerate their greens in April and September. Over time, the golf course’s grass and turf are compacted by golfers. Specialized machines called “aerators” puncture the soil and sprinkle new grass seeds and fertilizer, resulting in healthy new growth. During aeration, golf courses are closed for a day or more. However, it can take several weeks for aerated greens to return to perfect condition. If you are planning to play golf in Hawaii and are particular about the condition of the course, you may want to avoid traveling to Hawaii around April and September.

An aeration schedule for golf courses in Hawaii is provided below for your convenience.

 The Aeration Process:

Turf compaction happens when players walk on turf, compacting the grass and limiting oxygen supply to the roots. In order to reverse this natural consequence of golfing, aeration is conducted. Using spikes to remove turf with soil promotes healthy oxygenation of the turf.  Aeration is essential to maintaining a well conditioned turf.
