Many fruit crops must experience enough cool weather before they come out of winter dormancy. This internal “clock” ensures that they don’t begin to bud out and flower too early in the year when they run the risk of experiencing a cold snap that could damage tender leaves and new growth. With this tool, users can explore accumulated chill hours for the current season from several common fruit models. To use this tool, select a model or models from the menu below and then either type a location into the map search or click on the map to select a location. Then scroll down and click “Submit” to see model outputs for your selected location.
