1. Soil

The soil for pansy growth needs to be fertile, loose and well drained, with pH of 5.4-7.4

2. Illumination

It is very sensitive to light. When the light is sufficient, its stems and leaves are lush, its flowers are dense, its flowering time will be earlier and its flowering period will be longer; But the lack of light will lead to poor flowering. You have to accept more than 4 hours of light every day

3. Moisture

They like wet soil environment and are not drought resistant. When growing, they should pay attention to keep the soil moist, but do not accumulate water; The seedling stage should be slightly dry to prevent wetting from diseases and pests

4. Temperature

The optimum temperature for its growth is 15-25 ℃ and 3-5 ℃ at night. Do not place it in the environment above 25 ℃ for a long time, otherwise the plant will be difficult to blossom and cause overgrowth, and its seeds will be stunted and difficult to survive even if they bear fruit

5. Fertilization

When applying fertilizer, we should pay attention to thin fertilizer and frequent application. At the beginning, we can apply nitrogen fertilizer, such as urea; Phosphate fertilizer can be applied near the flowering stage, and 0.2% potassium dihydrogen phosphate aqueous solution can be applied at the bud pregnancy stage. After flowering, fertilization should be reduced and maintained in time
