1. The flowering period of Corydalis

The flowering period of Corydalis is closely related to the sowing time. It can bloom two to three months after conventional sowing. Because the suitable temperature for germination of Corydalis seeds is 15℃-20℃, it is generally chosen to sow seeds in early spring, so that you can enjoy the beauty of Corydalis flowers in summer. In the middle and lower reaches of the Yangtze River in autumn, the temperature is just right. In these areas, sowing can be done in mid-to-late September, and the landscape can be formed by December. For planting in northern areas, it is generally chosen to sow and raise seedlings in the greenhouse from January to February, and they will bloom around March to April. In the hot summer, if you have equipment that can lower the temperature, it is also a good choice to raise seedlings in the summer for autumn flowering.

2. Maintenance of Viola during its flowering period

The growth period of pansy is generally 3-4 months. Compared with pansy, its development period is shorter, about 2 weeks. However, Corydalis is very heat-resistant. Generally, the flowering period of Corydalis will be extended when there is sufficient sunlight. During the flowering period of Corydalis, you can fertilize it appropriately. Coryola is relatively sensitive to the concentration of flower fertilizer, and the general concentration is not higher than 150ppm. In addition to N fertilizer, K fertilizer can also be added to the fertilizer. During the flowering period, the liquid fertilizer described above can generally be applied once a week. Topping before flowering and during the growth period can promote the growth of side branches, increase the number of flowers per plant, and extend the flowering period.

3. Prevention and control of pests and diseases

< p>Pests such as aphids, thrips, and red spider mites may be encountered during the general cultivation of pansy. During the cultivation process, attention should be paid to improving the cleanliness of the growing environment to avoid infection with the above-mentioned pests. Common diseases during cultivation generally include leaf rot, downy mildew, powdery mildew, black root rot, etc. Proper watering and fertilization management can promote the rapid growth of plants. Generally speaking, it is recommended to water in the morning to avoid excessive leaf humidity at night. If the pH value of the soil is not suitable, it will easily lead to black root rot, and a suitable soil pH value can greatly reduce the probability of infestation by the above diseases.
