How to Plant Cornflower
Today's mini experience sharing: how to plant cornflower and the content about cornflower planting methods and timing in the field of green plants and flowers. Next, the editor will provide you with detailed answers.
Cornflowers are best sown in autumn. The blooming period of cornflowers is from February to August. 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. Cornflower is a herbaceous plant of the asteraceae family, with a variety of species, very beautiful, and common flower colors include blue, pink, and purple. They can be used as cut flowers and are more suitable for potting or as garden plants for ornamental purposes. Below is a detailed explanation of the reasons why spring and autumn are suitable for sowing cornflowers and the precautions for sowing.
I. Spring
Spring is suitable for sowing cornflowers, and the sowing time should be in mid-spring. In the south, it is best to sow from mid-March to early April. In the north, sowing can be done from March to May. This is because early spring sowing requires keeping warm, and attention should be paid to moisturizing due to the high evaporation of water in early spring. Moreover, as cornflowers are not heat-tolerant, late spring sowing is not conducive to seed germination and seedling growth due to high temperatures.
Usually, sowing from April to May can result in flowering from July to August. Early spring sowing in February in a greenhouse can lead to flowering in May.
II. Autumn
Autumn sowing allows for the fastest seed germination. Autumn sowing is better than spring sowing, as new plants propagated in autumn grow stronger and flower faster and more than those in spring. 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. Autumn sowing can lead to flowering in the following spring.
Sowing can start after the beginning of autumn, usually in August or September. The seeds can germinate in the early spring of the following year, and flowering can occur from April to August.
III. Sowing Precautions
Select plump seeds, and pre-treatment for seed germination can be used before sowing to improve germination rate and accelerate germination time. The soil for sowing should be kept moist, and after sowing, ensure that the ambient temperature is between 18 to 25°C. Usually, germination can occur within 10 to 13 days.
Cornflower is an annual or biennial plant. In China, it can overwinter outdoors without withering. Therefore, after autumn sowing, it is best to move the flower pot to a sunny indoor location for maintenance during the winter.
