When to Plant Borage in Ohio

Growing Borage in Ohio: Complete Guide

Borage (Borago officinalis) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Ohio falls between April 17, 2027 (Zone 7a) and May 2, 2027 (Zone 5b), once soil temperatures are consistently warm enough for germination.

Because Ohio stretches across 4 USDA hardiness zones (5b, 6a, 6b, 7a), planting windows can shift by as much as two to four weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 60 days to maturity, Borage fits comfortably within Ohio's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Borage requires full sun to partial shade and moderate moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
