If properly maintained and managed, jasmine can bloom three times a year, and the opening time of each flower is generally 1-2 days.
Jasmine likes warm and humid, and grows best in a well-ventilated semi-cloudy environment. The most suitable soil is slightly acidic sandy soil containing a lot of humus.
Most varieties are afraid of cold, drought, frost, wet waterlogging and alkaline earth. When the temperature is below 3℃ in winter, branches and leaves are vulnerable to freezing damage, and will die after a long time. Deciduous lianas are very cold-tolerant and drought-tolerant.
