Planting Instructions

Can I Start Prairie Flax from Seed?

Plants can be propagated by seeds, cuttings, or division.  Division is difficult.  Cuttings can be taken in the spring and potted until roots are well established. Can be transplanted in the summer.

Seeds can be direct broadcast into the garden in late fall or early spring.  Late fall is optimal.


When Do I Plant Prairie Flax?

Plant in the late fall to early spring.  Prairie flax seeds benefit from chilling so a late fall planting may help to pre-chill the seeds to reduce dormancy.


Where Do I Plant Prairie Flax?

Prairie Flax plants perform best in light, well-drained soil high in organic matter but will grow in nearly any good garden soil that receives full sun and is well-drained. Incorporating several inches of organic matter into the soil when preparing the bed will improve growth and development.

Prairie Flax Plant Care and Maintenance

Once established, most perennials require very little routine care and maintenance.

How Often Should I Water Prairie Flax?

For many perennials, average rainfall is sufficient to keep the plants healthy.  Supplementation may be necessary in droughty conditions. Do not overwater.


Should I Fertilize Prairie Flax?

Most perennials do not require a specific fertilization regiment.  Fertilizing decisions should be based on a soil test.  If a soil test cannot be obtained and you feel that your perennial bed would benefit from fertilization, keep it light.

Fertilize the soil around the plant at least 6” from the plant base. Irrigate into the soil.
