How to Plant Cornflower Seeds
This article introduces how to plant cornflower seeds and the planting methods and precautions for cornflowers, a green plant and flower introduction. Let's dive into the details together.
Cornflowers are best sown in autumn. The blooming period of cornflowers is from February to August, and they can bloom in the spring of the following year. Spring is also suitable for sowing, and flowers can be seen in the same year. Cornflowers are herbaceous plants of the asteraceae family, with diverse varieties and beautiful appearances. Common flower colors include blue, pink, and purple. They can be used as cut flowers, and are more suitable for potting or as ornamental plants in gardens. Below is a detailed explanation of why spring and autumn are suitable for sowing cornflowers and the precautions for sowing.
I. Spring
Generally, sowing in April to May can lead to flowering from July to August. Early spring sowing in February in a greenhouse can result in flowering by May.
II. Autumn
Autumn sowing allows for the fastest germination of seeds. 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 promote vernalization of 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 lead to flowering the following spring.
Sowing can start after the beginning of autumn, usually in August or September. The seeds will germinate the following early spring and can bloom from April to August.
III. Sowing Precautions
Choose plump seeds and use seed germination techniques before sowing to improve germination rates and speed up germination time. The soil for sowing should be kept moist, and the ambient temperature should be maintained between 18 and 25°C after sowing. Germination usually occurs within 10 to 13 days.
Cornflowers are annual or biennial plants. They can survive the winter outdoors in our country, but the plants will not wither. Therefore, after autumn sowing, it is best to move the flower pots to a sunny indoor location for maintenance during the winter.
