Changing pots of soil for longevity flowers once a year can effectively solve this problem. Because the root system of longevity flower is underdeveloped, capillary roots account for the majority. If the soil remains unchanged for a long time, the nutrients in the basin soil are not enough for plants to grow. Moreover, watering the flowers with tap water for a long time will make the pot soil alkaline, which is not conducive to the growth of longevity flowers who like weak acid soil. These will hinder the absorption and utilization of nutrients by roots, and in the long run, it will also cause the phenomenon of stiff seedlings. Therefore, it is suggested to change the soil for longevity flowers every spring after flowering or when they wake up in late summer and early autumn.

Too much watering leads to too much water, which is also a reason for the stiffness of longevity flower seedlings. When the soil structure in the basin is too thick, the root system will suffocate or rot, and it will not be able to transport water and nutrients to the branches and leaves normally, which will hinder the normal growth of plants. Because the stem of longevity flower has a strong ability to store nutrients, even if the root system or stem is rotten, no obvious changes can be seen in a short time. If there are rotten roots or stems, you must cut off the rotten parts of the longevity flower in time and cut off the healthy branches and leaves again.

Hot summer is hard for longevity flowers. Because longevity flowers don't like high temperature, they usually let themselves spend the summer in a dormant way. There will also be some longevity flowers whose leaves become bigger and yellow and their seedlings become stiff due to poor management in summer. When you meet yellow leaves in summer, you must pick them in time, and there is not a leaf left. As long as the roots are still alive, new leaves will definitely grow in autumn, and the pregnant buds will bloom. Of course, we should also pay attention to whether plants have enough fertilizer.

In autumn, we will move the longevity flower to a place with strong light intensity. Supplementing fertilizer properly and giving sufficient light can promote the occurrence of photosynthesis and the accumulation of nutrients in leaves, and promote the formation of flower buds. When the branches produce small flower buds, it is still necessary to pay attention to not less than 4 hours of light every day, keep the pot soil slightly dry, and supplement potassium dihydrogen phosphate every 10 day, which can promote the flower buds to open.
