How many days is the flowering period of Chinese rose?

There are two flowering periods of Chinese rose throughout the year, namely, June and 65438+ 10, with May as the initial flowering period and September -65438+ 10 as the final flowering period. However, each rose can only bloom for two or three days, the long one can bloom for five to seven days, and the long one lasts for two weeks.

The reason why the flowers of Chinese rose are getting smaller and smaller is 1, and the light is insufficient.

Chinese rose likes sunshine. If cultivated in a cool environment for a long time, the branches will be slender, the leaves will be thin and pale, the flowers will be few and small, the color will be dim, and even no flowers will bloom. Pay attention to increasing the light. Open-air cultivation is most beneficial to the growth of Chinese rose, and try to ensure the light.

2. The temperature is too high

When the temperature exceeds 30℃, the growth of Chinese rose is inhibited, the flower buds are no longer differentiated, the differentiated flower buds and the formed flowers develop slowly, the buds are few, the flowers are small, the color is dim and the flowering period is shortened. This situation mostly happens in buildings. Generally, flowerpots are cultivated on the cement balcony facing south. At noon in summer, the balcony temperature is high, and the soil in the basin dries easily and is exposed to the scorching sun. The rising temperature of the basin wall will burn the tender roots, lead to weak growth, not only fine flowers, but also lead to plant death. To prevent this from happening, some measures should be taken.
