In the middle and late ten days of October, we should move the night primrose into the shed. The temperature in the shed should be kept between 8-12 ℃. If it is lower than 5 ℃, the leaves of night primrose will wither and fall off, or even die.
Nocturnal fragrances like a sunny and well ventilated growth environment. From the beginning of May to the end of September, it is suitable to put nocturnal fragrances on sunny places or balconies for maintenance. It should be noted that the hot sun should be avoided at noon in summer.
Summer is the peak season for the growth of evening primrose. At this time, the basin soil must be kept moist, and the watering times can be increased appropriately according to the situation. If it is the seedling of nocturnal, spray water on the leaf 1-2 times a day.
In the growth process of nocturnal, liquid fertilizer should be applied every 10-15 days or so. After late April, thin liquid fertilizer should be applied every half month to ensure that nocturnal flowers continuously from mid May
It is suitable to choose the loose and fertile soil with good drainage. In general, you can choose peat soil or rotten leaf soil to thicken river mud in the proportion of 3:2 and a small amount of farmyard manure to mix and prepare, and fill about 1 /5 of the bottom of the potted plant with granular bricks, which is conducive to drainage.
It is suitable for basin changing at the beginning of April. When the basin is changed, some old soil and roots are removed, and new culture soil is replaced, and heavy cutting is carried out to promote the development of new branches. After changing the basin, keep the basin soil moist, but avoid ponding. If there is a slight droop of tender leaves after changing the basin, water it in time.
It should be noted that the strong fragrance of night primrose is not conducive to human health, and it is easy to cause dizziness, insomnia, cough and other symptoms when stored indoors for a long time, especially for patients with high blood pressure and heart disease. Therefore, it is not suitable to put nocturnal incense indoors, especially in the evening, it should be moved to the balcony or outdoors.
