Reprogramming the irrigation system to provide better coverage.
Auditing the irrigation system and repairing malfunctioning stations and zones.
Micromanaging the worst areas with handwatering and supplemental fertility.
Incorporating soil amendments to the ‘dry’ areas to help retain moisture and nutrients.
Amending poor conditions on #7 fairway
Each of these actions will contribute to overcoming the problem. A realistic expectation is to manage the ‘peaks’ and ‘valleys’ until the inconsistencies dissipate and reliable turf is experienced.
