Bermuda grass should generally be watered deeply but infrequently to promote deep root growth and drought tolerance. The typical watering frequency and amount depend on the season and climate conditions:
- During the growing season (spring and summer): Water about 1 inch per session, once or twice a week is common, or every 3 to 7 days depending on heat and rainfall. Some recommend watering 3 times a week for about 15 minutes each in hot, dry conditions, while others suggest once or twice weekly with about 1 inch of water per session
- In cooler months (fall and winter): Watering frequency decreases significantly. For example, in fall, watering 1 to 2 times per week with fewer cycles is sufficient, and in winter, watering may be needed only once a week or even less if there is adequate rainfall. In some cases, watering can be turned off during winter unless there are dry, cold spells
- Watering time: Early morning watering is best to reduce disease risk, allowing grass blades to dry during the day
- Adjust based on signs: Overwatering can lead to weeds, thatch, and fungus, while underwatering causes grass to turn bluish-gray and not spring back after stepping on it
In summary, water Bermuda grass deeply (about 1 inch) once or twice a week during active growth, reduce frequency in cooler months, and always adjust based on weather and lawn condition. Avoid daily watering unless the lawn is newly seeded or very young
