When to Sow Blue Cornflowers
Let me tell you about when to sow blue cornflowers and the planting methods and timing for green plants and flowers. If there are any mistakes, please feel free to correct them!
Cornflowers are best sown in autumn. The blooming period of cornflowers is from February to August, and they can bloom the following spring. Spring is also suitable for sowing, and flowers can be seen in the same year. Cornflowers are herbaceous plants belonging to the Asteraceae family, with a variety of species that are very beautiful. The common flower colors are blue, pink, and purple, which can be used as cut flowers, and are more suitable for ornamental potted plants or garden plants. Below are the reasons and precautions for sowing cornflowers in both spring and autumn.
I. Spring
Generally, sowing from April to May can result in blooming from July to August in the summer. Early spring sowing in February in a greenhouse can lead to blooming in May.
II. Autumn
Autumn sowing allows for the fastest seed germination. Autumn sowing is better than spring sowing, as new plants grown from autumn sowing are stronger, bloom faster, and produce more flowers. An environment of 0 to 10°C can have a vernalizing effect on the seeds, promoting seed germination and flower bud growth. Moreover, as cornflowers are relatively cold-tolerant, they grow best in cool environments, and autumn sowing can result in blooming the following spring.
Sowing can start after the beginning of autumn, usually in August or September. The seeds can germinate the following early spring and bloom from April to August.
III. Sowing Precautions
Select plump seeds and use seed germination techniques before sowing to improve germination rates and accelerate germination time. The soil for sowing should be kept moist, and after sowing, ensure the environmental temperature is between 18 to 25°C. Generally, germination can occur within 10 to 13 days.
Cornflowers are annual or biennial plants that can survive outdoors in winter in our country, but the plants will not wither. Therefore, after autumn sowing, it is best to move the potted plants to a sunny indoor location for maintenance during the winter.
