Windows below are from Penn State Extension, Starting Your Summer Vegetable Garden—Seeds or Transplants?, retrieved 2026-10-10. The page gives dates for much of Pennsylvania, not for named regions. Spinach is the crop placed in a named month, April, and that month is read as April 1 through April 30. Phrases such as “early April,” “mid-April to late May,” and “late May to early June” stay phrases, because the page does not give them a day. Crops the page times only as “after the danger of frost has passed” or “early spring,” with no month, are left off these windows.
Date checks use your device’s calendar and appear after the page loads.
