If it's the primrose planted at home, rather than the ready-made one, it needs good maintenance to keep it blooming. In its seedling stage, when there are about 2 to 3 leaves growing out, we should plant them in small pots in time.
About a month later, when its seedlings are tall enough, it's almost time to bloom. In order to make it develop better, we also transplant it into a large pot again, so as to facilitate the growth of its roots and provide favorable conditions for later flowering.
In the process of its growth, we must keep the basin soil moist all the time, but it can't be too wet. In addition, we need to keep up with the nutrition. Generally, we can add fertilizer to it every 10 days or so. The fertilizer is mainly liquid nitrogen fertilizer, and then when it starts to grow flower buds, we need to apply a little phosphorus fertilizer properly, so that we can increase its flowering, and then when the flowers are in full bloom, we need to reduce fertilizer properly, and when the flowers are out of bloom, we need to stop applying fertilizer.
In addition, before each fertilization, we can't water it, we should let the basin soil dry a little bit, so that it will be more conducive to the absorption of fertilizer, and when fertilization, we can't let fertilizer spread on the leaves, to prevent burning the leaves, so that we can wait for it to blossom next time.
It likes the warm environment very much, so in winter, we should pay attention to the temperature can not be too low. Generally, it should be kept at 10 degrees, so that it will bloom in the next spring. In addition, we should pay attention to ventilation when we raise it at ordinary times. In summer, we can't let the temperature exceed 30 degrees, let alone direct sunlight. We must properly shade it.
In order to keep it blooming, when it blooms, the temperature and light need to be adjusted well. In addition, it is necessary to cut off the residual flowers and pedicels in time and add some fertilizer, so as to keep it blooming.
