Its flowering time is generally uncertain, because different sowing time will also affect its flowering time. But under normal circumstances, it will not bloom until April to May. If you want it to open during the Spring Festival, you can plant it in August of the previous year. If you want it on labor day, plant it in October of the previous year. Generally, if you don't have much demand for its flowering period, it will bloom from April to May.
If you want to make it bloom longer, you need to adjust the temperature properly. Generally, the temperature is the best when it is between 10 and 15 degrees. If the temperature is too high, it may shorten its flowering time greatly.
When it blooms, we can't let it direct to the sun. It's better to put it in the indoor astigmatism place, and occasionally bask in the sun. If the light is too strong, the flowers will fall early.
It's important to water during flowering. If the permeability of the basin soil you choose is OK, just water it once a day. In addition, if the indoor air is too dry, you can spray some water properly to increase the air humidity.
When its flower bud begins to differentiate and gestate flower bud, pay attention to fertilizer selection at this time. It is usually based on phosphorus and potassium fertilizer. When the flower bud grows, it will stop fertilizing immediately.
