What these dates mean in Pennsylvania

Planting usually runs about 57 days, from May 10 to Jul 5.

That start date is about 6 days later than the middle of the 31 places in this data set that report soybeans planting dates (May 4).

Harvest usually runs about 57 days, from Oct 5 to Nov 30.

From the start of the planting window to the start of the harvest window is about 148 days in Pennsylvania, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Pennsylvania. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual dates from 20-year progress data (Oct 2010 edition), begin ~5% and end ~95% complete. Check your last spring frost and soil temperature, and confirm with your county extension office.
