A one–half to one inch planting depth is suggested in clay soils. Flax seed is comparatively small and may fail to emerge from greater depths, especially if crusting occurs. Inexperienced growers often plant too deep, especially if the soil is loose. Flax is usually sown with a grain drill.

How deep should flax be planted?

Seeding Depth Ideally, flax should be sown into moist soil, 1.0 to 1.5 inches deep with row spacing 6 to 8 inches. Flax seedlings are weaker and shallow seeding depth is more critical for vigourous emergence, however, too shallow and seeds may be prone to drought.

What is the seeding rate for flax?

Plant Stand A seeding rate of 30 to 45 kg/ha (27 to 40 lb./ac.) results in approximately 500 to 800 seeds/m2 (50 to 80 seeds/ft. 2). A seedling emergence rate of 50 to 60% is usually attained under farm conditions.
