Applying bone meal or some bean cake water before flowering can make the flowers more colorful, the flowers will be larger, and the leaves will be thicker. If not, it will be difficult for the flowers to bloom.
Under strong light conditions, its flowering period will be very short, but the color of the flowers will be brighter. On the contrary, under low light conditions, its flowering period will be longer, but the color will be a bit ugly. Whether it is long-term strong light or long-term low light, it will lead to the accumulation of nutrients.

Temperature also has a relatively large impact on it. If the temperature is too high, the root hairs will exist for a shorter time and the absorption capacity will be weakened. Therefore, the temperature should be controlled between 15 and 20 during the flowering period. In this way, the root hairs will exist for a longer time and the absorption of water and fertilizer will be much better.
You need to water it more when it is blooming, because it has greater water requirements at this time, and the humidity needs to be above 60, but it cannot be too high, and it will not work if it exceeds 80. It is best to compact the soil tightly, and then keep the temperature above 20, and do not allow the soil to harden, and the light should be stronger in winter.
