Flax: Sowing, planting and harvest calendar
When and how should you sow flax outdoors?
Before sowing flax, check the species and purpose: annual cultivated flax, Linum usitatissimum, is not always managed like an ornamental perennial flax. Spring generally suits annual flax once the soil is workable and retains moisture. Adapt the date to your climate and seed lot rather than to the air temperature on a single day.
Choose a sunny, freely draining area. Weed thoroughly, then prepare a fine, firm surface: small seedlings compete poorly with established weeds. Distribute seed evenly, in rows or broadcast according to use, at the density specified for the chosen type. Fibre production is normally denser than a spaced ornamental planting. Do not therefore give 20 to 30 cm between every seed as a universal rule.
Cover to a depth suited to the seed lot and soil texture without burying too deeply. Firm gently for good soil contact and water with a fine spray when necessary. Keep the seedbed moist during emergence, without a hard crust or standing water. Thin only if the purpose and stand require it. Avoid excessive feeding that can encourage stems to fall over. Follow the particular sowing and spacing requirements of perennial flax types.
