When to Plant Borage in Tennessee

Growing Borage in Tennessee: Complete Guide

Borage (Borago officinalis) is a crop that grows best when sown directly in the garden. In Tennessee, the right time to direct sow is around Sunday, April 12, 2026, once soil temperatures are consistently warm enough for germination.

Because Tennessee stretches across 4 USDA hardiness zones (6b, 7a, 7b, 8a), 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 Tennessee'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. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
