Planting Outdoors

From Early Spring TO Late Spring

Plant container grown plants into site having dug compost into the soil first.

 

Propagation by seed Spring

From Early Spring TO Mid Spring

Sow cornflower seeds outdoors where they are to grow from early spring. Choose a position in full sun on well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 3mm (1/8") in drills spaced 30cm (12") apart. Water the ground regularly, especially during dry periods. Germination usually takes 14-21days. When cornflower seedlings are large enough to handle, thin them out to 15cm (6") apart. Alternatively, grow cornflowers indoors in early spring for early summer flowering next year. Sow cornflowers on the surface of a good quality seed compost at a temperature of 18-23C (65-73F) and cover with a very fine sprinkling of compost or vermiculite. Do not exclude light as this helps germination. When seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to move outdoors.
