The time of flowering of evening primrose is introduced by the breeding method of evening primrose.

Each plant has its own characteristics, and evening primrose usually opens at 8-10:00 in the evening. The temperature is just right at this time. Next, let's learn more about the flowering knowledge of night incense.

When does evening primrose blossom

Generally speaking, the flowering period of nocturnal incense is from May to October, and the reason why it has such a large span is that it presents different seasons due to the influence of variety, temperature, humidity, soil and climate in the north and south. But we can already see that nocturnal incense blooms in summer night, which is what makes it hazy and blurred. In the north, the blooming season is in late June, while in the south, it is mostly from August to September. This is due to the high humidity caused by the summer heat in the south, which is suitable for night incense to bloom.

So why did evening primrose bloom in the dark night? There are two main reasons, that is, nocturnal incense, a plant that pollinates by ugly moths, is not small things such as bees like other flowers, and moths only appear at night, so in order to attract nocturnal moths to pollinate for him, nocturnal incense chooses to exert fragrance at night, which is the plant's ability to adjust itself to the environment. However, do you still have the habit of picking a flower on the tip of your nose and sniffing it in Nangang District?

Another reason is that nocturnal incense and stomata are diametrically opposed to many flowers. For other flowers, when the air humidity is high, the stomata approach; when the air humidity is low, it expands, while nocturnal incense does the opposite. If the air is very humid, its stomata will open wide, and the aromatic substances inside will expand more quickly, thus making it fragrant to the nostrils. At night, because there is no evaporation of the sun, the surface temperature drops suddenly, the cold air drops, and the humidity increases abruptly, which is why it is easy to get foggy at night. Of course, night incense is easier to open in such a humid environment, and it opens more and more intensely.

Night incense culture: night incense like loose, well-drained, organic acid soil. So the soil we want to choose is generally made of peat soil or rotten leaf soil, or even a small amount of farm manure, that is, the manure of all kinds of animals. When potted, the bottom should be filled with broken bricks in the shape of particles to facilitate drainage. But also choose a well-ventilated environment, from the beginning of May to the end of September, it is appropriate to put sufficient sunshine in the hospital or maintenance on the balcony. Although it likes adequate sunshine, it should avoid hot sun exposure at noon in summer.

If summer is the peak growing season, the basin soil must be kept moist and watered twice a day, except for adequate fertilizer. If it is a seedling, it should be sprayed to the leaves once or twice a day. After the arrival of winter, it should be moved indoors, such as the temperature is lower than 5 ℃, the leaves will wither and fall off until death, so friends in the north should think twice. In this process, it should also be noted that it is best to apply fertilizer every two or three months, and pay attention to the prevention and control of diseases and insect pests.
