In the process of cultivating pansy, it is best to choose the mixed soil of bone powder, humus soil, bark, fine sand and perlite as the culture soil. During the growth period, the illumination time should not be less than 6 hours every day. When the temperature is higher than 35℃ in summer, it is necessary to properly shade and ventilate, and keep the basin soil dry when watering.

First, the cultivation method of pansy 1, substrate requirements

Corydalis tricolor is a succulent root system plant, which is suitable for growing in a substrate rich in nutrients and with strong water permeability. When potted at home, some bone powder can be put at the bottom of the basin as a base fertilizer, and a proper amount of mixed soil of humus soil, bark, fine sand and perlite can be added to the basin, stirred evenly, and then a small amount of water can be poured in for normal maintenance.

2. Environmental management

Corydalis tricolor likes to grow in a warm and sunny environment, and its cold tolerance is very poor. During the growth period, it should be treated with at least 6 hours of light every day, otherwise its leaves will be dull and grow slowly. If the temperature is higher than 35℃ in summer, it should be properly shaded and ventilated, and it should be placed in an indoor environment with good light in winter.

3. Suitable moisture

Corydalis tricolor has a strong drought resistance. In the process of watering at ordinary times, it should be carried out on the principle of not watering, but pouring thoroughly. Under the condition of high temperature in summer, the plants are in a semi-dormant state, so watering should be reduced, water should be controlled in winter, and ventilation should be paid attention to frequently. Don't water in winter when it is lower than 5℃, and keep the pot soil dry.

4. Pruning treatment

Pruning is one of the cultivation methods and matters needing attention of pansy. Proper coring and thinning can be carried out in spring and summer, which is beneficial to the growth and development of the plant and enhances its ornamental value. Then, in winter, the stems, withered stems and leaves that affect the appearance are cut off to promote the optimal concentration of nutrients in the root system.

Second, matters needing attention

Due to the poor cold resistance of pansy, water should be moderate in winter, mainly by spraying water, which can be carried out in the form of spray. When the weather is dry, wet cloth can be used to wipe the leaves to ensure the cleanliness of the leaves, and watering should be carried out at noon to avoid damaging the adaptability of the roots.
