Persian cornflower: Sowing, planting and harvest calendar
How do you sow Persian cornflowers outdoors?
Sow your Persian cornflower, a flowering perennial, in a bright place with well-drained soil. Choose mild weather once the ground has warmed. Remove weeds and loosen the surface for a fine seedbed. You can also use a pot with drainage holes outdoors and seed compost to monitor moisture and distinguish seedlings more easily.
Moisten soil before sowing thinly. Cover seeds with a fine layer of crumbly soil or vermiculite and press gently. Water with a light spray without moving seeds. Keep steady moisture without standing water until germination. Around 20 °C encourages emergence, but its speed outdoors varies with weather. Watch for drying and slug damage to young shoots.
After emergence, let the first true leaves develop and thin crowded plants. For their final position, reserve roughly 50 to 80 cm between clumps according to the form and packet instructions. If sown in pots, separate seedlings into individual pots once developed enough to handle, holding a leaf rather than the stem. Keep roots moist during this operation and continue measured watering through establishment.
