Methodology

Where do these planting months come from?
Each range is a stored planting window for this crop and climate. A month that is not listed has no stored window. It is not a recommendation to skip planting.
Why can the same season appear more than once?
When two sources give different months for the same season, both ranges are listed. They are not averaged, and the gap between them is not filled in.
How are grower notes different from official windows?
Farmer field notes are labelled Farmer field experience, with the month they were noted. They are not official department windows, and they are not yet verified against official sources.
