When to plant early cabbage in Pennsylvania

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.
