Flax is a frost-sensitive annual that prefers full sun and fertile, well-drained soil. Flax thrives in cool, moist growing conditions.
Flax can be direct seeded outdoors in spring as soon as the soil can be worked. Optimal soil temperatures for germination are 65-80°F. Sow seeds 1/8" deep. Seeds will germinate in 20-25 days. Thin seedlings so mature plants are 4-6" apart. Flax readily self-seeds year after year.
If growing for fiber, harvest flax stems before seeds fully mature (120-140 days). Allow some plants to set seed to ensure flax plants the following year.
