When to Plant Endive in Oklahoma

Growing Endive in Oklahoma: Complete Guide

Endive (Cichorium endivia) is a crop that grows best when sown directly in the garden. In Oklahoma, the right time to direct sow is around Sunday, March 8, 2026, once soil temperatures are consistently warm enough for germination.

Because Oklahoma 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 85 days to maturity, Endive fits comfortably within Oklahoma's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Endive requires partial shade to full sun and regular (keep moist) moisture. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
