Golf course grass is always green.

Reasons for Keeping the Grass Green
The grass on a golf course is maintained at a consistently vibrant green to enhance the aesthetic appeal and playability of the course. Golf courses are often seen as symbols of prestige and exclusivity, so maintaining pristine conditions is crucial. The green color not only looks good but also plays a role in how well the ball can be seen by players.

Maintenance Practices
To keep the grass green, golf courses employ various maintenance practices. These include regular watering, fertilization, and mowing. Irrigation systems ensure that the turf receives adequate water, even during dry spells. Fertilizers provide essential nutrients, promoting healthy growth and a deep green color. Mowing is done frequently to maintain an even height, which is critical for the speed and roll of the ball on greens.
Additionally, some courses may use turf paints or dyes during winter months or drought periods to maintain appearance.

Environmental Considerations
Maintaining lush green grass requires significant resources and can have environmental impacts. Water usage, especially in arid regions, is a concern. To address this, many modern golf courses are designed with water conservation in mind and utilize native plants and drought-resistant grass varieties.
Moreover, sustainable practices such as integrated pest management (IPM) reduce the reliance on chemical pesticides. Organic fertilizers are also becoming more popular as they promote soil health and biodiversity.

Impact on the Game
The condition of the grass directly affects gameplay. Greenskeepers must balance the needs of aesthetics with playability. Faster greens, for example, require shorter grass and more precise mowing, while fairways need to be kept at a longer length to provide a challenge without being too punishing.
The overall health of the turf ensures consistent ball roll and reduces the likelihood of divots or uneven lies, enhancing the experience for golfers of all skill levels.
