Lobelia chinensis likes humid environment, slightly resistant to light humidity and drought, and cold-resistant. It can overwinter naturally in the field, and is born in wet places such as ridges, grasslands, ditches and streams. Artificial planting is better in the wet place beside the ditch, and sandy soil is better. Lobelia chinensis likes warm and semi-shady growth environment, and the suitable growth temperature is between 25℃ and 30℃, so it is not cold-resistant.
The wintering temperature is high in winter, and it is best to keep it above 15℃. Below this value, the growth of Lobelia chinensis may stagnate. When the temperature is higher than 30℃ in summer, water it to avoid its death. Sufficient light is needed, and the longer the light time, the faster the flowers will bloom. When the sun is strong in summer, you need to pay attention to shading in time.
