Planting calendar

Windows below are from Ohio State University Extension, Planning for the Garden, excerpted from OSU Extension Bulletin 287, Home Vegetable Gardening, retrieved 2026-10-10. The dates are for a normal season in central Ohio. The same page says spring planting runs about two weeks earlier in southern Ohio and about two weeks later in northern Ohio. Those shifts are a sentence, not a second column, so the dates below stay the central Ohio dates. The PDF says the tables are excerpted from Bulletin 287 by Utzinger, Brooks and Wittmeyer, 1991, now out of print.
