Breeding method

temperature

In the middle and late October, the night primrose should be moved into the shed. The temperature of the shed should be kept between 8-12 ℃. If it is lower than 5 ℃, the leaves of night primrose will wither, fall off and even die.

illumination

Nocturnal incense likes a sunny and well ventilated growth environment. From early May to the end of September, it is suitable to put nocturnal incense in a sunny place or balcony for maintenance. It should be noted that it should avoid exposure to the hot sun at noon in summer.

watering

Summer is the peak season for the growth of evening primrose. At this time, the basin soil must be kept wet, and the watering times can be appropriately increased according to the situation. If it is a larch seedling, spray water on the leaf surface 1-2 times a day.

apply fertilizer

In the growth process of evening primrose, liquid fertilizer should be applied every 10-15 days. After late April, thin liquid fertilizer should be applied every half a month, which can ensure that evening primrose can bloom continuously from mid May.

soil

It is suitable to choose loose, fertile and acidic soil with good drainage. Generally, the potted soil can be made of peat soil or rotten leaf soil, thickened river mud, mixed with a small amount of farmyard fertilizer in the ratio of 3:2, and filled with granular broken bricks at the bottom of the pot about 1 / 5 deep, which is conducive to drainage.

Change Basin

It is suitable to change pots in early April. When changing pots, remove some old soil and old roots, replace them with new culture soil, and re cut them to promote the development of new branches. After changing the basin, keep the basin soil moist, but avoid ponding. If the tender leaves sag slightly after changing the basin, water it in time.

matters needing attention

It should be noted that the strong floral fragrance of nocturnal incense is not conducive to human health. It is easy to cause dizziness, insomnia, cough and other symptoms if placed indoors for a long time, especially for patients with hypertension and heart disease. Therefore, nocturnal incense should not be placed indoors, especially at night, it should be moved to the balcony or outdoors.
