How to Use This Chart
- The date of planting for each crop listed in the chart is given by the number of weeks before the beginning of the Persephone Period, ie, the last 10-hour day.
- Your planting dates need to be back-scheduled by that number of weeks from the last 10-hour day at your latitude. To identify this exact date for your location, use an app or website such as Sundial - Solar & Lunar Times or SunriseSunset.
- The crops are grouped, as outlined in the KEY, to reflect their reliability for winter-production success, from relatively easy to more challenging, as gauged by experienced high-latitude four-season growers.
- Click on the crop names to browse specific varieties we have trialed and selected for winter-harvest success.
