Penn State Extension publishes Region III dates to the day, so the source windows below are day-exact. Penn State Extension’s York County Master Gardener seed planting guide is built on a May 1 last frost and an October 1 first frost. It publishes one direct-seed window per crop - column 8 "Earliest date to sow seeds" and column 9 "Last date to sow for full crop before first frost" - and no separate autumn window, so no row here is a fall window. Column 9 is derived from the October 1 first frost and is calculated to allow a more complete harvest, not a single picking. The latest closing date in the whole table is August 22 (radish).

Calculated for York (York County). This catalog carries 6 frost sites for York County, Pennsylvania; each one publishes its own measurement, and opening this page with JavaScript lets you pick another.
