key Key Use our Overwintering Planting Chart to time your plantings for earliest spring harvest.  Keep in mind that the planting dates are back-scheduled from the last 10-hour day at your latitude.  The number of weeks before the Persephone Period is calculated for each listed crop.  The crops are grouped, as outlined here in the Key, to reflect their reliability for overwintering success.  Click on the crop names to view varieties selected for successful overwintering.
