Sprinkler rotation times should ideally be...

1. Variable based on weather conditions

2. Determined by soil type

3. Relatively the same

4. Adjusted monthly

The correct answer is: Relatively the same

Sprinkler rotation times should ideally be relatively the same to ensure uniform application and efficiency in watering. Consistent rotation times allow for even distribution of water across the landscape, which is crucial for maintaining healthy plants and minimizing water runoff or pooling. This uniformity helps ensure that all areas receive adequate moisture and helps to prevent over- or under-watering in various sections of the landscape. While other factors like weather conditions, soil type, and monthly adjustments can influence watering schedules, having a consistent rotation reduces the complexity of scheduling irrigation events. Instead, these other factors can be monitored and factored in during seasonal adjustments, rather than being the primary basis for setting rotation times. The goal is to establish a reliable baseline that maintains efficiency while still being adaptable to current needs based on environmental variables.
