Generally speaking, the flowering period of evening primrose is from May to October. The reason why the span is so large is that it is affected by the variety, temperature, humidity, soil and north-south climate, so it presents different seasons, but we can already see that evening primrose blooms in summer nights. In the north, the flowering season is in late June, while in the south, it is mostly in August-September. This is due to the high humidity caused by the summer heat in the south, which is suitable for the blooming of evening primrose.

1. There are two main reasons: night primrose is pollinated by ugly moths, unlike other flowers, which are bees and other small things, and moths only appear at night. Therefore, in order to attract moths to pollinate for him, night primrose chooses to smell at night. This is the self-adjustment ability of plants to the environment. However, do you hear whether there is still a habit of picking a flower on the tip of the nose in Nangang District?

2, there is another reason is that night primrose and stomata and many flowers are diametrically opposed, other flowers are air humidity, stomata approach some; air humidity is small, it expands, and night primrose is opposite. If the air humidity is very large, its pores are very open, and the aromatic substances inside can expand more rapidly, thus fragrant. At night, due to the absence of evaporation from the sun, the ground temperature suddenly drops, the cold air drops, and the humidity suddenly increases. This is the reason why it is easy to fog at night. Night primrose is of course easier to open in such a humid environment, and the opening is more intense.

Therefore, the soil we want to choose is generally made of peat soil or rotten leaf soil, and even a small amount of farm manure, that is, the feces of various animals. When potted, the bottom should be filled with granular broken bricks to facilitate basin drainage.

2, if in summer is the growth season, in addition to applying sufficient fertilizer pot soil must be kept wet, if necessary, irrigation twice a day. For seedlings, spray the foliage once or twice a day. After the arrival of winter, it should be moved indoors.

In this process, but also pay attention to, every two or three months the best fertilizer, but also pay attention to the prevention and control of pests and diseases.
