Direct sow after last frost date. Sow more seeds every two to three weeks for successive blooming. If you need to start seeds indoors, use peat pots and harden off seedlings carefully to avoid transplant shock.

Sow seeds by barely covering them to a depth of 5mm (1/8″). Seeds germinate in 20 to 25 days. Thin seedlings to 15cm (6″) apart.

Cut back about half of the flowering stems in early summer to extend the blooming period. Grow in any well-drained soil with a pH range of 5.0 to 7.0 and avoid fertilizer and manure. Rich soil reduces blooming. Linum dislikes root disturbance, so it is not suitable for transplanting – it’s better to simply sow more seeds.

Linum is harmful if eaten.
