When to Plant Borage in Hawaii

Growing Borage in Hawaii: Complete Guide

Borage (Borago officinalis) is a crop that grows best when sown directly in the garden. In Hawaii, the right time to direct sow is around Friday, January 8, 2027, once soil temperatures are consistently warm enough for germination.

Because Hawaii stretches across 6 USDA hardiness zones (10b, 11a, 11b, 12a, 12b, 13a), planting windows can shift by as much as six to eight 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 Hawaii'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. Hawaii's year-round warmth allows continuous planting, though elevation and trade wind exposure create distinct growing pockets.
