When to Plant Sorrel in Unknown

Growing Sorrel in Unknown: Complete Guide

Sorrel (Rumex acetosa) is a crop that grows best when sown directly in the garden. In Unknown, the right time to direct sow is around Tuesday, January 13, 2026, once soil temperatures are consistently warm enough for germination.

Because Unknown stretches across 6 USDA hardiness zones (5a, 7a, 7b, 8b, 9a, 9b), 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, Sorrel fits comfortably within Unknown's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Sorrel requires partial to full sun (4-6 hours) and moderate (1 inch/week) moisture. Check your local forecast for humidity and heat advisories that may affect timing and pest pressure.
